Let's face it: We would all love it if all dogs would cherish each others' company and embrace having a new friend join the family—no squabbles or major disagreements. Instead, many dog lovers who can't seem to be content with owning only one dog struggle when bringing home a new dog and introducing him or her to their current dog/dogs.
Why is that? Perhaps it stems from us rushing through the process and the preconceived notion that dogs are social beings, and as such, they should all get along as best buddies. After all, isn't that why there are dog parks scattered almost everywhere? Aren't Aunt Mary's five beagles the perfect example of the successful cohabitation of dogs? How can a dog walker walk so many dogs together if dogs don't have an innate predisposition to get along?
Well, this brings us to the very first tip in successfully introducing a new dog to a current dog. This one tip is often missed and may be a primary cause for things not working out as desired.
Tip 1: Lower Your Expectations
Among dogs, things are not always as rosy as it happens in Disneyland. Just ask any dog trainer or behavior consultant, and they will have their own stories of brutal dog-to-dog interactions gone wrong. Sorry to burst your bubble, but dogs aren't always that eager to share their living quarters with a stranger dog.
As a dog trainer and behavior consultant, I can attest that problematic relationships among dogs sharing the same household rank as one of the top three main reasons people seek assistance with their dogs. And the issues are not always easy to solve, especially if the problematic behaviors have been rehearsed for quite some time.
Some desperate cases even need a referral to experts in the field who have made dog behavior their primary area of specialty: veterinary behaviorists and certified applied animal behaviorists.
Many dog owners expect dogs to be social beings that look forward to having a new playmate to play tug on a rope and share their sleeping spots together for hours on end. It, therefore, comes as a shock when new dog-to-dog introductions go sour as the expectations at stake are high. Perhaps lowering them is, therefore, a very important step that plays a crucial role in successful introductions.
Look at the Situation From Your Dog's Perspective
After all, if we think about it, even us humans are far from being the perfect example of amicable interactions. For instance, let's take a look at divorce rates. With 40 to 50 percent of married couples in the United States divorcing, we are not a very good species at getting along. Things may be especially rocky in the beginning, and while some couples survive, others sink, never to resurface again.
So let's put ourselves in our dog's shoes. How would you feel if your landlord picked up a random stranger and brought him/her into your home to live with you and expected you to get along with him/her? You would likely see this as an invasion of privacy, and you would feel very uncomfortable: "Eek, what is this new person doing in my home? Is this move a long-term one for real? I don't want to share my living space with this person!"
Dogs, though, are much more direct than people. They do not secretly hide their thoughts or say "please" or "sorry"; they're rather more explicit as they do not adhere to social etiquette. Their barks, growls and snarls say it all clearly: "Get out of my house!"
So the very first step for successfully introducing a new dog to an existing dog is to realistically put ourselves in our dog's shoes before plunking down a new dog into our dog's existing household. Here are some additional tips to prevent upsetting the delicate state of balance our dogs have achieved in their lives up till today.
Tip 2: Introduce on Neutral Grounds
If it takes two or more dogs to make you happy, it is your responsibility to up the chances for a successful introduction. Tip number 2 is often overlooked due to all the excitement in bringing new Fido home and the preconceived notion that dogs love other dogs as much as you do.
"Neutral grounds," as the name implies, refers to areas where your existing dog has no strong emotional attachment. So, skip introducing the dogs inside the home, skip the yard, and even skip in front of the home or other nearby areas where your resident dog may have shown an inclination to bark at stranger dogs. Remember: A dog's territory often stretches far past the fence line.
Your home and surrounding areas are often perceived by your dog as a safe place that encloses all the many amenities that make his life so wonderful (feeding areas, sleeping areas, play areas). Many dogs have quite a large "mental map" of their perceived territory and may dislike other dogs in any nearby areas, and these may include nearby roads and back ways.
There are several neutral places dogs may meet and get acquainted without having to feel threatened about ownership. A dog park, a pet-friendly store or a distant road where both dogs can meet and greet and then walk home together may be good places for the introduction.
How to Conduct the Introduction
Both dogs should be individually on leash with one person, and the leash should be kept loose. Remember: Tension may travel through the leash, and a tight leash may interfere with a dog's proper body language display and calming signals.
Let the dogs sniff each other. This allows them to gain some information about each other. Impolite sniffing behaviors should be avoided. Frontal meetings can be perceived as confrontational. Sniffing each other's rear ends is preferable, and the greetings are best if kept short and sweet.
Should there be any growling or lunging, it is best to give more space and not correct the dogs. This is communication. Correcting the dogs for displaying such communication over time may lead to dogs suppressing their growling and going straight to a bite. You do not want that.
In an ideal setting, both dogs will be happy to meet, and they may even try to entice each other to play. If it's safe to do so, and the area allows it, it may be helpful to watch the two dogs interact off leash; however, caution is often needed as a fight may erupt any time two unknown dogs meet. A plan should be in place to safely separate fighting dogs (for example, having blankets handy to toss on the dogs or making an abrupt distracting sound).
How to Walk Home Together
Following a brief meet and greet, a nice long walk together home may be ideal. Parallel walking is particularly helpful. In parallel walks, both dogs are on leash side-by-side. To err on the side of caution, I prefer to have the dog owners in between both dogs so that both owners are next to each other. This provides a slight visual barrier that prevents direct eye contact between dogs.
By the time the dogs are closer to home, they have hopefully relaxed enough that one owner can move to the other side, and then finally, both dogs can walk closer together. Of course, avoid this if you notice any signs of tension, no matter how small.
Tip 3: Create Positive Associations
Dogs live in a world of associations and you can take advantage of associative learning to help your dogs like each other. Obviously, this works up to a certain point. Some dogs will never completely enjoy each other's company to the extent of being able to safely share the same home.
The goal is to make wonderful things happen to dog number one when dog number two is present. Throw a party and make a major fuss. Let your dog feel like he won the lottery every time dog number two makes his appearance and enters the room. If you celebrate every time that dog number two appears, you are celebrating togetherness rather than one dog dreading the other dog's presence. To make this extra clear, make sure that when dog number two leaves, all these great happenings abruptly stop. No more fun.
Swap Your Dogs' Scent
The process of creating positive associations may even take place prior to the new dog's arrival. You can bring home a few items that carry the new dog's scent, leaving them around and leaving treats right on them or nearby. Then, you can replace them with other items that carry a stronger and fresher scent.
Some dog owners go as far as purchasing stuffed animals that resemble the breed and size of the new dog and play recordings of the new dog's vocalizations starting at a low volume and then increase the volume gradually. Food and initiation of enjoyed activities take place during these low levels of exposure. Exposing the resident dog to these stimuli prepare the dog for the new dog's arrival, just like when introducing a new baby.
Tip 4: Prevent Hard Feelings
Many dog fights in multi-dog households take place in presence of the owner, why is that? A good reason may be the fact that dogs have a tendency to compete over the owner's attention. To prevent hard feelings, it's best that each dog is given separate but equal time, especially initially.
It is very tempting when getting a new dog to provide him/her with oodles of attention, yet, this will likely upset the resident dog. There's fortunately a way around this. The ideal method would entail giving the new dog attention, but never in front of the existing resident dog.
And please, when you do give attention, make it as discrete as possible: no loud smooching and cooing that can be easily overheard by the resident dog. Remember that dogs have very sensitive hearing.
Best to give attention in the farthest room of the house while the other dog is provided with extraordinary toys and treats, or even better, while Rover is in the yard exploring or playing fetch with another family member so to not upset anyone.
Playing some music or turning on the TV at a good volume may help filter all the cooing. Do the same for each dog ensuring quality one-on-one time for each.
A Dozen More Tips for Heightening Chances for Success
- Pick dogs of opposite sex. Aggression among female dogs is very common, and fights between competing males are common as well.
- Find a dog that matches your existing dog's energy levels.
- Ideally, pick a dog similar in size. A big gap in size may promote a phenomenon known as predatory drift.
- Consider that significant age gaps may lead to a younger dog continually pestering an older dog to play which may lead to squabbles. It's important that younger dogs are exercised enough so that they are not constantly trying to get older dogs to play.
- Spay and neuter both dogs.
- Exercise both dogs prior to the introduction.
- Maintain your existing dog's routine.
- Feed dogs food and valuable treats or bones in separate areas at first to prevent fights over food. After some time, it may be possible to feed them gradually closer under supervision. Use caution.
- Keep toys and other high value chewing items out of reach to prevent fights.
- Have a plan and ready access to tools to safely split up fights should they erupt.
- Invest in calming aids to lessen stress. Pheromones under the form of plugins or calming collars can help make the introduction go smoother.
- Consider that introducing a new puppy to an older dog may have more challenges. Here are 10 tips to introduce your puppy to an older dog.
- Avoid falling into the school of thought that both dogs should “work out” their relationship issues on their own. This theory has led to countless bloody fights.
When Things Don't Work Out
Unfortunately, things don't always work out. Some dogs may be best buddies, others may just tolerate each other and some may never get along. Generally, many dogs show signs of adjusting in two weeks, but in some cases, it may take longer. Enlisting the aid of a dog behavior professional may help.
Dogs should be carefully managed in the meantime by providing separate areas and never leaving them together. In some specific cases, re-homing the new dog may be the best thing to do to prevent stress in both dogs.
Introducing a new dog to an existing dog comes with risks. The utmost caution is needed. Dogs may get severely injured, and dog owners may become victims of a redirected bite while attempting to separate fighting dogs.

Congrats on getting a new dog! She sounds like a great match for him. It's so nice when things go smoothly as such.
Heidi Thorne from Chicago Area on November 11, 2018:
Update: We got a new friend for our boy. She's been amazing! We went with a dog that's the same age as our current dog which I think was a great choice. Plus, the male/female energy helps. We looked for one that was a good personality fit and let them meet on neutral territory.
Hope all is good with your pack! Have a great day!

Linda, so true that there are always a risk when introducing a new dog. Good to hear things always worked out fine in your family. You certainly must be doing everything right.
Adrienne Farricelli (author) on September 23, 2018:
Heidi, our boy has been coping fairly well, thanks. We are not yet considering adding another dog for now. I wrote this mostly for a client who was struggling and using it as a hand-out for other clients in a similar position.
Linda Crampton from British Columbia, Canada on September 14, 2018:
This is interesting and useful information. My family has been lucky because every time a second dog has been brought into the home there has never been aggression. I know there is a chance that problems will appear in this situation, though. Thanks for sharing the great advice.
Heidi Thorne from Chicago Area on September 14, 2018:
Well, with the title of this post, are you considering adding another 4-legged "kid" to your house? We're still going back and forth about a replacement companion for our guy.
When we have paired up our pets in the past, we found, too, that pairs of the opposite sex were great yin and yang energies. As well, we also did a lot of the things you suggest and have rarely had issues with competitiveness and fighting, except when one gets a little to much in the other one's space or face. But it never ending up in anything bloody or even long-lived. Just a little spat between friends.
Hope you and your pack are recovering from your recent loss. Thanks for sharing your expertise, as always. Have a great weekend!
Ethel Smith from Kingston-Upon-Hull on September 14, 2018:
Very useful advice. It is easy to convince yourself your dog needs and wants a little friend when it may love being yours alone. I have been considering another dog for a while but ours may be better on his own
Adding Another Dog to Your Home
Dos and Don'ts for Bringing Another Dog Into Your Home
Considering adding another dog to your home? First, consider the dogs you already have.
“In my opinion, when you are looking to add a second dog to your home, first and foremost, you’ve got to look at your dog’s personality,” says Brad Phifer, CPDT-KA, director of pet behavior services for Broad Ripple Animal Clinic and Wellness Center in Indianapolis. This includes knowing your dog’s play style, energy and socialization level, and playmate preferences.
Before you decide to add a second (or third, or more) dog, here’s what you need to know to make all your dogs feel comfortable.
For starters, Phifer tells WebMD that there are no set rules about good dog matches because all dogs - even within the same breed - are individuals. So it's not necessarily true that female dogs match well with male dogs, younger dogs or older dogs make better second dogs, or that two puppies always do well together.
Introducing Your Dog to a Strange Dog:
It is almost guaranteed that when you and your canine buddy are out on a walk, you will come into contact with another dog.
Always ask the other owner if an interaction with their dog is okay. Some dogs may be timid or reactive, and interactions with them may not be ideal for either dog. If a meeting has been approved by both you and the other owner, you can proceed to let the dogs meet. Some dogs may act differently on a leash than they do when off-leash. This can be due to feeling trapped and that they cannot get away if an altercation occurs.
Once they come in contact, normal dog behavior will likely occur, and the dogs will sniff each other in greeting. Signs that the meeting is going well include relaxed facial expressions, play bows, tails wagging fast, and wiggling their hind ends.
Signs that the meeting is too much for either dog may include yawning, turning their heads away from the other dog, tense jaws, tails held low, shaking, and the hair standing up along their backs. These behaviors indicate the dog is nervous about the meeting, and it is best to separate the dogs and continue on your walk before the situation has a chance to escalate.
Don’t let your dog meet every dog they see on a walk switch it up and ask for periods of focus on you when passing another dog. This helps prevent Rover from lunging at every dog he passes, including those dogs that are uncomfortable with other dogs.
Dog-to-dog interactions are an important part of dog ownership. When performed correctly, they can be enjoyable for everyone. Remember to always take meetings slow, and if any dog appears to be nervous or anxious about the situation, increasing the distance is best. With well-trained greetings, your dog will happily anticipate the fun that they can have with other four-legged friends.
How to Successfully Introduce a New Dog to Your Current Dog - pets
Introducing a new pet into the home may end up being very easy, or it may be a delicate process that takes some time. How quickly your pets adjust to one another depends on their personalities. Some pets end up being the best of friends others merely tolerate each other. The goal is to make sure they can live harmoniously and happily together, even if they don't become best friends. Here are a few tips for making introductions.
- Allow your new pet to familiarize itself with its new home. Temporarily confine existing pets to a room to give your new pet a chance to feel more comfortable with its surroundings.
Introduce your pets indoors in controlled situations. Keep dogs on a leash and immediately put a stop to any aggressive behaviour. If you are introducing a cat to a dog, do not allow the dog to chase or corner the cat - even if it's out of playfulness or curiosity.
Give them time - don't force them together. Some pets are naturally more timid or unsure around other animals. Let pets adjust at their own pace. Pushing pets together before they're ready can make it a negative experience, which will take longer to overcome. If all they want to do is sniff each other through a gate at first, then let them be. Give them time to gain confidence and decide when to face his or her new housemates.
Praise, praise, praise - and give lots of rewards. Every time your new and old pet do something good with each other - even if it's something as simple as a bit of a wiggle or a wag - praise and reward. The idea is to associate each other with good things.
When introducing a cat to a dog, do NOT hold the cat in your arms. A frightened or nervous cat may scratch. Put the dog in a kennel or behind a secure gate and allow the cat to approach the dog.
Give your pets separate food and water bowls, in separate spaces. If you are introducing cats, also provide separate litter boxes. Feed your new and existing pets in different locations to prevent any conflict over food.
Be especially careful when introducing dogs or cats to caged animals. Dogs and cats can live in harmony with rabbies, guinea pigs, birds, etc. but should be introduced under strictly controlled supervision. Remember that cats are very agile, so placing a cage high up on a shelf doesn't necessarily protect the caged pet. Don't take any chances - one mistake could be fatal to your caged pet.
Always supervise your pets until you are absolutely sure they get along. Until then, separate your pets by confining at least one of them to its own room. Only allow them to interact with each other with your supervision.
Introducing a new pet into the home may take hours, days, weeks, or even months for your pets to completely adjust to one another. Patience and a positive attitude will help your new pet become a fully integrated member of the family as fast and as easily as possible!

Once you decide that you are ready to adopt a new pet into your home, there are some things you can do before it even arrives. If you have a blanket or toy with the new pet’s scent on it, allow your cat or dog to smell this item and get used to the new scent. Allow the new pet to do the same with your current pet’s personal items. Purchase a food bowl specifically for your new pet, and plan on feeding all pets separately to avoid any food aggression issues.
For cats, a good rule of thumb is to have one litter box per cat plus one extra and place them in different areas of the house. Lastly, make sure all pets are up to date on their vaccinations and parasite prevention. If you have any medical concerns about either pet, have them examined by your veterinarian prior to the introduction.
Keep in mind that you need secure housing for pocket pets like guinea pigs or hamsters. A scheming cat can remove a screen lid off of an aquarium or wrestle loose an opening from an unsecured cage.
Also, keep in mind the costs that are associated with a new pet, like for food, housing/bedding and veterinary care. Be sure to set aside a little financial cushion for unexpected emergencies and veterinary care.
