When you bring your new puppy home, it's an exciting time! You will be keen to get to know each other and to start building a trusting bond between your puppy and you and your family. You may also have another dog at home and will need to consider how to introduce a new puppy to your existing dog.
Dogs are social animals, but they can be territorial and also quite protective of their owners, so you do need to be mindful when you bring a new puppy home. It can cause anxiety and conflict, so it should be handled with care, as you want your dogs' first interactions to be positive, so you can build on their relationship.
In this article, we go through the process of introducing a puppy to another dog in a relaxing and positive way. Being prepared, using positive reinforcement training, and supervising both puppy and dog are all important steps for working through this potential challenge with ease.
When introducing a new puppy to your dog, you mustn’t just put a puppy with your established pet dog and assume that they will get along or work it out. This approach is very risky and can lead to a variety of problems, such as anxiety, destructive behaviours, or even aggression, and can really set you back in training your puppy and dog. You must positively approach the meeting and prepare yourself.
Make sure your puppy and your established dog both have their own space. This might be a crate each or a space to hide. They should also have their own bedding, blankets, beds, and toys. They should also have their own water bowl and food bowl. You will need to use positive reinforcement training to ensure each dog knows which is their space and their items to avoid resource guarding. If you encourage the puppy not to go near the other dogs' space, then this will help prevent possessiveness.
Choose a neutral place for introducing a new puppy to your dog. Choose somewhere fun, like a neighbour's yard or a local park. Try to pick somewhere that isn’t seen as an established territory by your older dog. Try to also make sure that the location is not too distracting for your puppy, as they will still have a lot of socialising to do.
It’s a good idea to ask someone to help you walk one of the dogs as you introduce a new puppy to your dog. Keep them apart to begin with, and don’t allow them to interact straight away. Just let them sniff the air and become aware of each other. Try to keep relaxed and slowly decrease the distance between them. They should remain calm and curious, sniffing each other calmly. Keep the leashes relaxed and use a positive, encouraging tone. You can offer treats to encourage good behavior.
Keep a careful watch on the body language of the two dogs. Dogs communicate a lot through their body language, just like humans do. You will need to look for signs of stress or aggression, such as stiff bodies, growling, snarling, prolonged staring, snapping, and raised hackles. If you see these signs, you should separate the dogs and try again at another time with a greater distance and a slower approach. You might want to seek professional advice from a veterinarian or a certified dog behavioral specialist.
The positive signs you are looking for when introducing a puppy to another dog are loose wagging tails, interested and gentle sniffing, relaxed postures, and bowing at each other. You might find that your older dog responds to your puppy's enthusiastic, lively behaviour with a growl or a bark. This is ok, as it is your older dog establishing their authority and setting a boundary. If they then calm down and play, it is fine, but be wary that this does develop into aggression.
Establish a daily routine with your puppy and dog, encourage them to play together, but supervise them until they are happy together. Be cautious about leaving them on their own too soon. Keep the puppy and dog's food bowl, toys, and quiet spaces separate. Don’t leave toys out and offer plenty of cosy spaces as alternatives. Try to manage your puppy's exuberant energy with your other dog’s, especially if the other dog is senior. Try to match their playtimes so they can both enjoy their time together.
When you're introducing a puppy to another dog, you can introduce treats as positive reinforcement once the dogs have adjusted to each other. When the interactions go well, reinforce the good behaviour with praise, affection, and treats. Make every interaction a positive experience. Reward both dogs with treats, praise, and affection when they behave well around each other. This reinforces good behavior and helps them associate each other with happy outcomes.
Introducing a puppy to another dog is a really exciting and rewarding thing to do. You really want your puppy to be able to settle in with your family and your established dog so you can work on building bonds and trust. By using positive reinforcement training and a calm and planned approach, you will find that you can gently encourage your puppy and dog to enjoy spending time together.
Keep training them and make sure both your established dog and your new puppy have their own space and things, such as bowls, to continue with a harmonious home. It’s also important to make sure you treat them equally so as not to invoke jealousy. Be careful to observe body behaviour, you're looking for positive and relaxed actions, and you will be on your way to a happy pack and multi-dog household!
