Getting ready for the introduction: Preparing your dog and puppy for their first encounter

Preparing for the first encounter is essential when learning how to introduce a new puppy to your dog. Both dogs need a safe environment and plenty of time to adjust to this change. Depending on your dog's breed and personality, the first encounter can be smoother than others. Each experience is different, and how your dogs react to each other will vary.

Successful introductions often begin with thorough pre-planning to avoid stress and ensure both dogs feel comfortable. Taking the time to familiarise your dog with the scent of the new puppy and providing a neutral meeting space can make all the difference.

In the following sections, we’ll discuss pre-introduction planning and gradual introduction—two vital components of introducing a puppy to an older dog. For a complete checklist and advice on preparing for the arrival of a new puppy, explore our guide to learn more.

Pre-introduction planning

Before the actual meeting, planning to introduce a puppy to an older dog involves a few crucial steps. Begin by assessing your current dog’s behaviour to understand its temperament and any potential triggers. Once your new pup is safely home and settled in, choose a neutral space for the initial meeting, like your garden or a place that feels neutral in your home. This will help minimise territorial instincts and provide a less stressful environment for both dogs.

If an outdoor meeting isn’t possible, at-home introductions are also appropriate. Using a crate door or baby gate is advisable to create a barrier that allows the two dogs to see and smell each other from a safe distance. This setup lets them become familiar with each other’s presence without direct contact, reducing anxiety and helping them feel more comfortable. Taking these steps ensures both dogs prepare for a positive first encounter.

Gradual introduction

How to introduce a puppy to a dog doesn’t always mean meeting face-to-face right away. An effective strategy involves familiarising your dog with the puppy’s scent before they meet. A week before the puppy’s arrival, offer your dog a blanket or toy with the puppy’s scent on it. This technique allows your dog to get used to the new scent gradually, which can make the first face-to-face meeting less overwhelming.

By implementing this scent introduction, you’ll set both pets up for a smoother transition as they get to know each other. Gradual introductions are vital to introducing a new puppy to your dog in a way that feels safe and controlled for both animals.

Initial meeting: First impressions

The first face-to-face meeting is a significant milestone in introducing a puppy to a dog. Choose a controlled environment where both dogs feel safe for the best results. Keep them on leads to maintain control and allow the dogs to approach each other at their own pace. Keeping this initial encounter short and positive is essential, helping both dogs ease into the situation.

During introductions, it’s crucial to focus on managing the adult dog’s reaction and rewarding good behaviour while prioritising the safety of your new puppy. Watch closely for changes in the adult dog’s behaviour or body language. If the adult dog shows signs of anxiety, distress, or aggression—such as stiffening, growling, or excessive barking—calmly separate them to protect the puppy and avoid a negative experience. Use treats to distract and reward calm behaviour in the adult dog before trying again later. Staying calm and relaxed will help both dogs feel more at ease, as they can sense your emotions and respond accordingly. Most 10-week-old puppies are naturally quiet, submissive to the adult dog, and accepting of new situations.

Let your dogs investigate each other naturally without forcing interaction. Remember, this is just the first step in introducing a puppy to an older dog. Gradual and positive experiences will set the foundation for a successful relationship.

Settling in: Managing the first few days with your new puppy and current dog

After the initial introduction, managing the first few days is essential to foster a positive relationship between your new puppy and your older dog. Begin with brief, supervised interactions that you can gradually increase over time. Keeping these interactions short initially allows both dogs to adjust at their own pace, which is essential for knowing how to introduce a puppy to an older dog. This gradual approach gives each dog time to become comfortable with the new dynamic without feeling overwhelmed, scared or stressed.

Establishing a consistent routine for both pets helps to reduce stress and promotes a sense of stability. Set up separate spaces where the dogs can have individual playtime, affection, and downtime. This dedicated attention ensures that both dogs feel secure and valued, helping to prevent jealousy or rivalry. Use treats and praise to reinforce positive behaviours during their shared moments. Providing each dog with attention, reassurance, and positive reinforcement helps them feel more at ease and builds trust.

Observing their interactions lets you learn when they’re ready for more frequent, extended contact. Taking things slowly and prioritising each dog's comfort will contribute to a harmonious adjustment period for both pets.

How to handle challenges when introducing your dog and puppy?

Introducing a new puppy to your dog is an exciting time. Most dogs will welcome a new member, but it can sometimes bring up challenges such as fear, anxiety, aggression, and resource guarding. Understanding these common issues and identifying uncomfortable emotions in your dogs will enable a smoother transition.

Here are some common challenges and ways to address them:

  • Fear and anxiety: if your dog appears fearful or anxious, gradual exposure to the puppy can help. Allow them to observe each other from a distance and offer comfort and reassurance. Use positive reinforcement, such as treats and praise, to encourage calm behaviour and build your dog’s confidence.
  • Aggression can arise when dogs feel threatened or uncomfortable. If your dog displays aggressive behaviour, separate them from the puppy and give them “time out” to calm down and learn boundaries. Reintroduce them gradually, and consider using treats to reward calm behaviour and encourage them when well-behaved.
  • Resource guarding: When dogs adjust to sharing their environment at home, guarding food, toys, or space is a common way to mark their territory. To prevent this clash, provide each dog with feeding and resting areas. Supervise interactions around prized resources and use distractions to manage guard behaviours.

Consider consulting a pet behavioural specialist for personalised guidance if these behaviours persist or escalate. Addressing these challenges early on can help create a positive environment and foster a harmonious relationship between your pets.

Building a strong bond between your puppy and dog

Once any initial challenges are managed, it’s time to focus on building a lasting bond between your puppy and dog. Consistent interactions are key to helping them feel comfortable around each other. Encourage shared activities, such as regular playtimes, walks, and training sessions, to foster positive experiences. Use positive reinforcement such as treats, praise, and affection during these interactions to create a positive association between the two. This approach helps build trust and strengthens their connection over time.

Providing opportunities for socialising your puppy with other dogs and people can further enhance their relationship. They will become more well-rounded and confident interacting with other pets and environments. Establishing shared spaces, like a common play area or resting spot, allows them to coexist comfortably and promotes an overall sense of integration. By supporting these ongoing interactions and experiences, you’re helping to create a harmonious and happy relationship that will last well beyond the initial introduction phase.

Key takeaways: Introducing your new puppy to your dog

Introducing a puppy to your existing dog takes patience, preparation, and a calm approach. Your pets may not always be best friends, but they should be able to coexist happily. If you experience any issues introducing your pets, you can ask a vet or pet behavioural specialist for advice. Start by familiarising your dog with the puppy’s scent and gradually work up to face-to-face meetings. When learning to introduce a puppy to a dog, managing early interactions carefully allows both dogs to adjust at their own pace, reducing stress and fostering positive experiences.

Veterinarians and pet behaviour specialists can provide guidance on issues like anxiety, aggression, or resource guarding. With consistent effort, you’ll see progress in introducing a new puppy to your dog and fostering a harmonious environment. Taking the time to ensure an excellent initial meeting will ultimately lead to a smoother transition.
