Try bathing your Chihuahua in oatmeal shampoo. You can also give them fish oil which is great for their skin and your coat. Another possible thing is the animal could be allergic to their dog food and most cases the protein is usually chicken.
Try animal medical center on Hillsdale near Big Lots. A great vet, who's kind and reasonable
No this facility is not a clinic or hospital. Meds available, over the counter. Visiting vet comes once a week for 2 hours
I'd call them before you go there.
