My dog is quiet and won't eat after dewormer, what should I do?

It is quite possible that he is nauseous from the medicine or he had a lot of worms which are now dying and that is causing him a tummy ache. Don;t feed him for 12 to 24 hours and then offer him some bland food such as boiled white rice and boiled white boneless chicken. Feed him small portions often. When he has regained his appetite he should be fine. There is a possibility that he will get diarrhea as well for a day or two as the body is going to try to get rid of the worms as quickly as possible.

It sounds like Millie is in pain. Please have her seen by a veterinarian immediately so they can assess her. Your vet may want to run diagnostic testing such as blood work to look for signs of infection (such as pancreatitis, which can cause diarrhea) or imaging such as x-rays to look for signs of injury.

Some dewormers may cause some gastrointestinal upset. It is good that Frankie will drink water and keep it down. Consider mixing in some unflavored PediaLyte. Try a bland diet again but warm it slightly or mix in a teaspoon of baby food to stimulate his appetite. Once he is eating regularly, transition slowly to the regular diet. If he still refuses to eat in the next 24 hours, have him examined by your veterinarian

Lelia not eating is a sign that she feels very bad and it's possible that it is related to a reaction from that dewormer although other causes are possible. The big concern is that she is very young and not eating. Puppies do not have the physical reserves of an adult dog. If she has not been eating since Monday then you need to take her in for an exam and medications to soothe her stomach. You don't want her to end up with low blood sugar and need a visit to the emergency clinic! If she will not eat her own puppy food, try warmed white meat chicken and plain white rice. This is not balanced but it will be fine for a few days. If she will not eat that, she is pretty sick. With young puppies, it's best to be cautious as they are fragile. Have her checked out today if possible.

I am not sure the type of dewormer or the vaccines that you used but vomiting often, lethargy, and not eating are not typical 2-4 days after vaccination and deworming. It is very concerning that she is having these signs and she could have an infection or possibly have a parasite that was not susceptible to the dewormer that you used. She really should be seen by a vet to determine the cause and treat. She may need an anti-vomiting injection, antibiotic, antacid, gastrointestinal protectant, dewormer, and/or other medications to treat. You could try to find a clinic that would work out a payment plan or apply for care credit and have her seen. Hope she feels better soon!

I'm wondering if you mean you gave Buddy a dewormer. You can see some stomach upset from giving a deworming treatment, as it can be due to the dead worms moving through the GI system, but it shouldn't stop him from eating completely. I would be concerned that he could have a medical illness causing him to not eat and have deceased drinking. Because of this, I would have him checked out by a vet right away. Best of luck.

Poor Waffle, stomach worms can make her feel nauseous which may be why she doesn't want to eat. If you can pick up some Hills a/d diet, or Royal Canin recovery from larger pet stores they are canned diets that are a mousse texture and become a liquid when stirred. They are also very flavorful so she might like the taste. You can also cook up some ground beef, but drain off any liquid fat and discard it before you feed her the meat. I do strongly recommend returning to the vet tomorrow to make sure there's not another reason for her to be unwilling to eat.
