Puppy and Adult Dog Introduction

Bringing a new puppy into your home is an exciting time, but it’s important to ensure a smooth introduction with your adult dog. A careful, step-by-step process can help both dogs feel comfortable, safe, and ready to bond. The following short guide provides practical tips to manage their first meetings and build a positive relationship between your new puppy and your resident adult dog.

Pre-arrival

Ask the breeder to provide a blanket the puppy has slept with to bring home (if you can get this in advance even better) you can introduce this to your resident dog to let them sniff and reward them straight after, to start pairing it with something positive do this a number of times. Take something of your older dogs with you when you collect your puppy that your resident dog has laid on, when you go to pick puppy up so they can start getting used to one another scent, this is called scent swapping.

Puppy safe space

Ensure you have prepared a safe space for your puppy, a puppy-proofed area with baby gates or a pen. When you get home ensure the older dog is in a separate room at first with someone if possible. Place any familiar items from the breeder in the pen before your puppy explores it. Let the puppy investigate their safe area first with the adult dog in a different room, letting them process, this lets the puppy know where to find their bed, water, food (if they haven’t eaten yet, remove food before the introduction), and toilet mat first.

Have one person sit in the pen with the puppy, letting them climb on their lap if needed, but it’s important to remain relaxed and calm to avoid showing any concern, no over fussing puppy.

Take something an item that smells of the puppy into the older dog and let them sniff the item and then give them a tasty treat.

Bring the adult dogs in on a lead so they do not charge at the pen and frighten the puppy, let them investigate in their own time. If the puppy panics have the older dog at a slightly further distance.

This setup allows the dogs to see and sniff each other through the pen without direct contact first. Reward calm behavior with verbal praise.

This gradual introduction gives the adult dog space to retreat if needed, while also allowing the puppy to adjust if they feel unsure.

Watch Body Language

Look for signs of stress (e.g., lip licking, yawning, turning away, stiff body language, cowering, bowing and barking) or playfulness, loose body (e.g., wagging tails or play bows). End the interaction if either dog seems particularly stressed or uncomfortable (e.g teeth bearing going at one another in a threatening manner). Observe how they interact through the pen initially.

Out of pen introduction

Once you have observed behaviour and feel they are relaxed with one another.

Allow short periods of supervised interaction indoors, gradually increasing their time together as they become more comfortable.

Avoid Resource Guarding

Remove toys, food, and chews during initial interactions to prevent disputes. Feed the puppy and adult dog separately in completely different rooms.

Avoid over-fussing either dog—there’s no need to overcompensate by giving the adult dog extra attention.

Respect Both Dogs’ Needs

Do not force interaction. Allow the adult dog to set boundaries. It’s normal for an adult dog to correct the puppy with a growl or snap if the puppy becomes too boisterous.

Provide Escape Routes

Ensure the adult dog has access to a quiet space where they can retreat if they need a break. The puppy should also have a safe area to relax and decompress.

Play

Play should be balanced see the signs to watch out for

Be Patient

The relationship may take time to develop. Consistency and calm management are key to fostering a positive bond between the puppy and the adult dog.
