I searched it on the internet that you give chihuahuas a bath once a month ...that's what I do with mine and she smells and looks just fine
How Many Times A Week Do You Bath A Chihuahua?
Hi, I have a male chihuahua and I love him dearly. He is just over a year old. Ever since he started lifting his leg, he slightly pees on himself bless his heart. I have to bathe my little chihuahua about ever 2 to 3 days. I do know that normally this breed can go a month, but not mine, lol!!!
