Q. We got very spunky pup til this morning he vomited once then had major diarrhea when he went potty this evening he just lays there and won't eatdrink
A. It's hard to say for sure... Is he vaccinated? How old? Knowing these would help us but in the mean time withhold food for 12 hours , water only. Then start him on a bland diet of 1:1 boiled chicken to white rice. If he starts to eat and keeps it down continue this till he has regular stool then over the next two days transition with his regular food. If he seems worse or still won't eat it's time to have a vet check him. If he's really young then you mah opt for the vet sooner.
