Last night my puppy stood up wobbly, then lay down, recovered in a minute and was lively, then vomited. This morning it was wobbly and could not stand, then recovered. What is wrong?

Occasional wobbly walking may come from nerve or intracranial issues, possibly poisoning. The best plan is a veterinary exam to confirm cause and severity for targeted medicine.

If a visit is hard, give pet broad-spectrum anti-inflammatories plus nerve nutrients like mecobalamin, B1 and B12, with small frequent meals. Observe 5-7 days; if improving, continue 2-3 weeks until recovery.
