Which method is appropriate when introducing a new puppy to other pets?

Gradually introducing a new puppy to other pets in a controlled environment with supervised interaction is the most effective method. This approach allows for careful observation of the pets' behaviors and reactions, ensuring that the introduction is as stress-free as possible for all involved. By monitoring their interactions, you can intervene if any aggressive or fearful behaviors arise, helping to set a positive tone for their relationship.

This method promotes a gradual acclimatization process, allowing the pets to familiarize themselves with each other’s scents and presence without overwhelming them. The controlled environment also ensures that the introduction happens in a safe space, minimizing the risk of injury or trauma.

Other methods, such as letting the animals play together immediately or isolating the puppy for weeks, can lead to negative experiences or delayed integration. Introducing them only through a barrier might limit their ability to form a genuine bond and can create an environment of fear or anxiety rather than fostering a friendly relationship.
