Get mats out before you bathe your dog, as the water can make it worse.
Also, pick up a bathing brush to gently massage the shampoo into your chihuahua’s coat. Opt for the smallest one you can find, as larger ones will be difficult to use on your diminutive dog. You can just use your hand, but a brush will help you work the shampoo deeper into your dog’s fur.
If you’re using a sink or bathtub, place a hair catcher in the drain to keep the dog hair from going down the drain.

Speak calmly to your pup the whole time, as it will likely not enjoy being in the tub. As you wash it, make sure to praise it the whole time.
You can also use a sprayer, but with a small dog like a chihuahua, the pressure may be a little overwhelming. If you do use a sprayer, set it on the gentlest setting and don’t turn the water on too strong.
Lather up the soap by rubbing it gently in circles as you move down your dog’s body. Don’t forget to massage some into your dog’s feet, too. Don’t put soap on your dog’s face.
Rinse your dog’s face with water but don’t get it in its eyes and ears.
If your chihuahua doesn’t startle at the noise, you can use a hair dryer, but set it on the lowest heat setting and hold it at least 6 inches (15 cm) away from your dog. Afterwards, you can let the dog shake off any extra water. Keep your dog in a warm area; chihuahuas are susceptible to cold until they are completely dry.
Brushing your chihuahua often will ensure it has a shiny, bright coat.
Be gentle, as chihuahuas have sensitive skin.
Your chihuahua will likely shake a lot of the cleaning solution out, and that’s okay. You can find a cleaning solution at your vet’s office or a pet store. Ask your vet how often you should clean your chihuahua’s ears.
