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 had these signs?
Any retching, gagging, lip licking or vomiting?
Are his gums pink or pale/white? Moist or sticky?
Any changes in his mouth (ie ulcers, sores, wounds, inflammation)? Any sign of tarter, damage, or discomfort with his teeth?
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, toys, plants, chemicals, etc)?
