Dog snout pain
(San Francisco, CA, USA)
Leia is a 5 year old, female blue-nose pit (not spayed). She hasn't eaten in two days (only nibbled yesterday morning) but is drinking water. She had a fever last night but it was gone by this morning and no diarrhea or vomiting at all. She yelps if I touch her snout. Her energy is very low, slowly moves when she goes outside to pee then comes right back inside. She hasn't consumed any house plants, though she tends to nibble on grass. What could be bothering her?
