Introducing a Foster Dog to Your Resident Dog: Setting Everyone Up for Success

The first introduction between your foster dog and your resident dog can help shape their relationship, so it’s worth taking things slowly. The goal isn’t to make them become best friends immediately—it’s simply to help both dogs feel safe, comfortable, and successful. 

Read on for some top tips from Underdog’s dog trainer, Jorge, on how to best ensure your resident dog and foster dog have a smooth introduction.

Introduce through Scent

One of the easiest ways to reduce excitement is to let the dogs get to know each other through scent before they ever meet face-to-face.

Try gently rubbing each dog with a clean towel or blanket, paying attention to areas like the shoulders and sides. Then swap the towels so each dog has a chance to investigate the other’s scent at their own pace. This allows them to gather information in a calm, low-pressure way.

Offer Independent Exploration

Another great scent introduction is to let your resident dog leave the house for a walk while the foster dog comes inside to quietly explore and sniff. After a few minutes, have the foster dog leave, then bring your resident dog back inside. 

Your resident dog can investigate all the new smells without the added pressure of another dog being present. This simple exercise can make the eventual meeting feel much less novel.

Be Strategic with Location

When it’s time for the first in-person introduction, choose a neutral location whenever possible, such as a quiet sidewalk or grassy area. Keep both dogs on loose leashes and reward calm behavior with praise and treats. 

Rather than asking the dogs to greet head-on, allow them to walk in the same direction with some space between them. Parallel walking helps dogs become comfortable with each other’s presence naturally and often leads to more relaxed interactions.

Use Body Language as Cues

Pay attention to each dog’s body language. Loose bodies, soft eyes, relaxed tails, and choosing to sniff the environment are all positive signs.

If either dog appears stiff, overly focused, or uncomfortable, simply create more distance and give them time to decompress. There is no prize for rushing an introduction.

Lead with Positive Reinforcement & Patience

Remember, every interaction should build confidence. By using positive reinforcement—rewarding calm choices, giving the dogs space, and allowing them to progress at their own pace—you’ll help create a positive association with one another. 

Patience in the beginning often leads to a smoother and more successful foster experience for everyone involved.
