Why is my puppy sick, not eating or drinking after his shots?

I have this male puppy named Charlie. He hasn’t been feeling very well. He was throwing up Friday but I gave him his shots Saturday and wormed him and he hasn’t thrown up or nothing anymore the throw up was just like spit tho. He’s lost a lot of weight and is just laying around tho and won’t eat or drink since Saturday!?? What can I do or give him to help???

Poor guy. It sounds like he may be experiencing a severe vaccin reaction. We treat these with a steroid shot and antihistamine shot. You will need to take him to your vet for treatment for this. B/c of the severity of his condition it is unlikely anything over the counter will help him recover. He also should be tested for parvovirus since he is so young and this is likely his first vaccination. You can try force feeding him some boiled plain chicken and rice or cottage cheese and 1-2 tsp of honey or karo syrup to keep his blood sugar up, until you can get him seen. I hope that your pet Charlie is able to make a full and speedy recovery. Best of luck and take care.
