Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
Would you say he is eating half what he usually would? More? Less?
Any vomiting, retching, gagging, hard swallowing, or lip licking?
Any drooling, grinding his teeth or pawing at his mouth?
Are his gums pink or pale/white? Moist or sticky?
If you press on his belly, does he have any discomfort, tenderness, or tensing?
Could he have eaten something he should not have (ie bones, string, plants, chemicals, etc)?
Has he had any diarrhea
