Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today.
Was the dose the correct one for Fred's size?
Any retching, gagging, lip licking, drooling, or vomiting?
Are his gums nice and pink (not white/pale)? Moist or sticky?
If you press on his belly, any tensing, tenderness, discomfort, or pain?
Could he have eaten anything he should not have (ie bones, toys, plants, chemicals, human meds, etc)?
