However gentle or used to other animals your existing cat or dog may be, it is important to remember that their reaction may not be all you hoped for when introducing a new pet. To ensure your new arrival is safe and protected, as well as providing a clear boundary for your older pet, keeping your puppy or kitten in a crate is a great way to introduce them slowly.
By using a crate that allows your puppy or kitten to clearly see out and your older dog or cat to see in, you’ll make them accessible to each other in order for them to get used to one another’s presence, without putting your younger pet at risk if you need to leave the room.
For a puppy or kitten, your home is new to them and will feel like a huge space – keeping them contained in a crate with access to food and water (as well as some cosy blankets!) will help them to settle without feeling too overwhelme
2) Try introducing on mutual ground
If your dog is particularly protective of your home, try introducing them to your new puppy on mutual ground, such as the local park. This will help the two to establish a bond and get to know each other’s scent, without your older dog feeling that their territory is being invaded.
