Chihuahuas are often known for their stubborn personality. But when it comes to being with their owners, they are sweet and tender dogs. Many Chihuahuas don't often get along with other dogs. They would rather be the sole pet in the house and the only dog on the planet. If you have multiple dogs, you're going to need to teach your Chihuahua to know how to get along with them. You're going to want all of your dogs to be comfortable in your home. If you take your dog out to dog parks or to a pet store, or even to the veterinarian's office, your Chihuahua is going to need to know how to behave and not be overly aggressive. Even a small dog such as your Chihuahua can get into trouble if his attitude is not in check. You don't want to be responsible for your Chihuahua biting another dog because he doesn't know how to get along.
The key to teaching your dog to get along with other dogs is to ensure the Chihuahua is social. As early as you can, socialize your Chihuahua. If you get your Chihuahua as a puppy, start as soon as he has all of his shots. You can socialize your puppy Chihuahua with people before his shots are done, but wait until he's had all of his shots before you introduce him to dogs you do not know, such as dogs at the dog park or a pet store. If this is an older Chihuahua, you are rescuing and bringing into your home with other animals, introduce your dogs to your new Chihuahua slowly and methodically. Getting your Chihuahua to be social is key to having him understand how to get along with other dogs. Remember, the commonality between your Chihuahua and other dogs is they will both do just about anything for delicious food.
Bring your Chihuahua together with other dogs slowly. Be sure to have lots of tasty treats for both dogs. If there are multiple other dogs in your home, you may ask a friend or partner to help with introductions. If you plan to bring your Chihuahua around other dogs outside your home, start with dogs and owners you know. Chihuahuas tend to do best on a harness instead of a collar and leash. If your Chihuahua is aggressive or in danger or harming another dog, pulling him away with a harness is safer than tugging on a leash attached to a neck collar. These little guys can become injured easily with a leash and collar.
