Socialization is extremely important for you, your family and especially your puppy. This should not be a problem because puppy socialization classes are usually not hard to find. It’s very important for you to learn how to socialize your puppy so you will know what types of behavior you should correct. Any aggressive behavior toward people or other animals of any kind should be stopped very early in your pup’s life so he will know that aggressive behavior will not be tolerated. Some puppies have their own ideas of what is their territory and home and may not be very generous when it comes to sharing but would much rather chase the intruders away. We have to reprogram the puppy’s thinking to make him understand that chasing the cat or iguana or whatever other pet you may have, is not acceptable.
Ask Before You Get Another Dog to Be Sure the Dog is Fine With Other Dogs and Cats if you Have a Cat
When you do adopt a new dog or puppy into a home with other dogs, it is recommended to introduce the new puppy to your current dogs or puppies on neutral territory such as a park or taking both dogs for a walk together to gradually get them used to each other. Then, if they seem to be getting along, you could try encouraging them to play in your yard for a while. Hopefully, neither dog will be overly possessive and they will become friends quickly. Some obedience training would be a good idea for both pups.
If you do have any cats or other critters or if you have another dog, be sure to make it clear to the shelter or rescue group very early in the search process that you are looking for a dog or puppy that is good with other dogs and other animals. It’s best to find out before you bring a dog home and end up having to return him because he doesn’t get along with your current pets. That is a very difficult and sad situation and it’s best for everyone involved if it can be avoided.
Be Patient, Everything Will Get Better With Time
After the puppies have both calmed a bit give them each a small reward, such as a morsel of some favorite food. Be sure to give the puppy lots of verbal praise and affection when it is not barking or trying to get to the new animal as this will show the puppy that you are accepting of the new pet’s presence and you expect him to be also.
One last point to keep in mind is that just like humans, not everyone is going to get along. There will be days where the puppy and the cat are going to feud or the iguana will get cantankerous and slap the puppy with his tail for the fun of it. Some puppies were just never meant to live in harmony but with a lot of patience and a little direction you can make your household fairly peaceable most of the time.
