Should You Get Another Dog?
Some people decide to get a puppy as their dog ages. The idea is to help mitigate the pain of losing the beloved pet when the time finally arrives. This can be good or bad, depending on the circumstance. If your rottweiler is very old, he may look on this new puppy as an interloper. A puppy will take most of your time and energy, leaving little time for your old dog. Your rottweiler may feel neglected and may become aggressive or short-tempered with your new pup.
There are dogs that tolerate puppies well. Sometimes a puppy can spark new life into an old dog. Something new and exciting can shake an old dog from the routine enough to make him feel young again. Some older dogs are quick to become the puppy's aunt or uncle and are delighted to show the newcomer the ropes.
Whether another dog or puppy is accepted largely depends on you and your rottie. If your rottie gets along with other dogs and puppies, perhaps getting a puppy might be the right choice. At the same time, you must make the time to have your rottie feel extra special. Don't stop doing things with him now that you have the puppy; otherwise, he will associate the lack of attention with the appearance of the interloper.
Would your adult rottweiler be pleased with a new friend?
When you introduce the two, always choose a neutral area such as a park. Let your rottweiler greet the newcomer while on leash. Praise him for good behavior, and discourage bad behavior. It may a take a few sessions before you can let your rottweiler loose with the other dog or puppy.
