Tips for Introducing a Companion Dog

Introducing a new companion dog to your Saint Bernard can be successful by focusing on the initial meeting, managing feeding times, and supervising interactions carefully.

Initial Meeting and Socialization

When introducing your new dog to Saint Bernard, we should choose a neutral location like a park. This prevents territorial behavior from either dog.

We should keep both dogs on a leash, allowing them to sniff and observe each other from a comfortable distance. Gradually bring them closer if they show calm behavior. It’s important to stay relaxed and avoid showing any anxiety, as dogs can sense our emotions. Reward both dogs with treats and praise for positive behaviors during this first meeting.

After the initial introduction, we should engage in short play sessions. Monitor them closely to ensure that interactions stay friendly and peaceful.

Managing Feeding Times

Feeding times can sometimes cause tension between dogs. We should feed our Saint Bernard and the new companion dog in separate areas to avoid any food aggression.

Establish a routine for feeding times, keeping them consistent each day. This routine helps both dogs know what to expect and reduces stress.

We should also use individual bowls for each dog and remove them immediately after eating. This practice prevents them from guarding or stealing each other’s food. If we notice any signs of aggression or anxiety around food, it’s best to consult a professional trainer for additional advice.

Supervising Interactions

Supervision is key when introducing a new companion dog. We should closely watch their interactions, particularly during the first few weeks.

If any play becomes too rough or one dog shows signs of stress, separate them calmly and allow a break. It helps to provide each dog with their own space, be it a crate or a separate room, where they can retreat and relax.

We should also give each dog individual attention and training. This ensures that both dogs feel valued and helps to reinforce their bond with us. Positive reinforcement is crucial, so we should reward good behavior with treats, toys, and praise. Regularly practicing commands with both dogs can also help maintain harmony in our home.
