My puppy is 9wks old and has worms, I brought him to the vet today and they treated him with medicine. I am home with him now but he appears very very weak and its 12 hours later. He is not eating or drinking and is vomitting whatever he has in him, which is not much so a lot if just spitting up. I am so scared, is this normal after treatment? What should I do?

Hiya I no how you feel when my brothers pup was 9 weeks he was the same he wouldn't eat an when he did it went right through him, he should be OK in a few days because once they av been wormed he will get bk to normal, my brothers pup had round worm an he was OK after he had his tablets, some dogs will be sick when you give them the tablets but you can also buy a paste that's in a tube aswel its like a syringe which we use because the dog was sick with the tablets, anyway try not to worry he will be OK xx stacey
