Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today.
How long has he been showing signs?
Does he circle in the same direction each time?
Any head tilting, tremors or pressing his head into walls/things?
Any retching, gagging, lip licking, drooling, or vomiting?
Are his gums pink or white/pale? Moist or sticky?
If you press on his belly, any tensing, tenderness, discomfort, or pain?
Could he have eaten anything harmful (ie bones, toys, plants, chemicals, human meds, etc)?
