I have a 7 week old chinese crested (hairless). She seems to have some swelling around her eyes, mouth, and ears. Also these areas are very pink. She does not have a fever, and is eating and drinking normally. About a week ago, the vet did a skin scraping to check to see if it was mange, and it was not. It is not scaly, or dry - just very pink. Her eyes are very watery as well. She also keeps chewing on her front paws - which seem as though they may be pink and swollen as well. Could it be allergies to something? She doesn't seem sick or too uncomfortable, but I am concerned. Any ideas on what could cause this?
