Basic Instruction

As soon as you can, teach your Rat Terrier Chihuahua Mix the fundamental instructions (such as “stay,” “sit,” “come,” etc.). These instructions, together with obedience training, make you the pack leader and safeguard your Rat-Cha in social circumstances. A well trained Rat-Chi will halt his activities and pay attention to his owner. They want to please others and are quick to pick up on simple command principles. You can use the following steps to assist in bettering your training of your Rat-Cha:

  • All the training, housebreaking is the most important. Make sure you take your leashed Rat-Cha dog for walks around the neighborhood. Your dog will become accustomed to your home as a result. Even though he’s a puppy, you should transport him throughout the entire house.
  • Having a leader is ingrained in a dog’s nature. You must therefore act as theRat Terrier Chihuahua Mix as you are its owner. Your Rat-ears Chi’s will perk up as you speak, as you will see. This shows your dog is paying attention to what you’re saying and will submit to your authority. Therefore, deliver the instructions with firmness, love, and praise. Despite its fury and stubbornness, the Rat-Cha will eventually carry out your instructions.
  • The simplest technique to teach a Rat Terrier Chihuahua Mix to sit when instructed is to touch its rump and press it down while using the word “Sit.” After some time, take your finger out to see if the Rat-Chi is still sitting. Repeat the steps if he begins to stand up. The little puppy will quickly pick up how to sit. When he learns to sit solely on command and without your help, praise him and give him a snack.

After the Rat-Chi has mastered the fundamental commands, you can advance to harder training.

Bathroom Training

The Rat Terrier Chihuahua Mix puppies learn how to control their bladder and bowels between the ages of 12 and 16 weeks. Because of this, this is the ideal moment to begin toilet training them. Take the puppy out to use the restroom if it is in a cage or box after meals, after naps, before going to bed at night, and just before you are about to leave it alone.

It will learn where to go potty and pee if you take your Rat-Chi there every day. Always give him praise and rewards for a job well done. Never chastise or penalize your pet for a small, unintentional error. Clap loudly to let it know that something unacceptable has happened if you can catch it in the middle of the task.

Leash Training

In order to avoid getting frustrated when the leash is on, leash training is also crucial. Never attempt to drag your dog by the leash. Use only a short leash and avoid tightening it up too much. Walk in front of him because dogs love to follow their owners [1].

The sole secret to successful training is reward and perseverance. This will make it simple and quick for the Rat-Chi dog to comprehend commands on the leash.


Despite their small size, Rat Terrier Chihuahua Mix have enormous spirits and aren’t shy about letting their presence be felt. Rat-Cha dogs might be prone to aggression and other behavioral issues, so owning one isn’t for everyone. However, their love for their cherished people makes them popular pets.

Since they don’t require a lot of space and prefer to spend the most of their time curled up on their special person’s lap, they are particularly well suited for single apartment residents. Rat-Chas are the best choice if you’re looking for a “The Bachelor” watchdog buddy, but they won’t make the best exercise partners.
