Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
How long has he been doing so?
Any retching, gagging, coughing, or change in appetite?
Any nasal or eye discharge?
If you press on his belly, any tenderness, tensing, or pain?
Any chance he ate anything he should not have (ie plants, chemicals, medications, bones, toys, etc)?
