Puppy won't eat/drink after tapeworm meds. How to prevent dehydration?

Hello and welcome to Petco Pet Education Center, formerly Petcoach. If Peggy has a large worm burden (lots of worms) then she likely feels sick and doesn't want to eat, and likely won't want to eat until the worms are gone. If the medication that your vet gave is a dewormer (typically a liquid called Panacur/Fenbendazole), then you can give it without food. This might clear out the worms and get Peggy eating again. If the medication is an antibiotic (Metronidazole, Amoxyclav), then this needs to be given with food. You can also talk to your vet about trying an anti-nausea medication to see if this helps with the appetite. If Peggy has abdominal pain, or is vomiting, please have her seen right away as high worm burdens can lead to a very life-threatening condition called intussusception. Best of luck with Peggy, I hope she feels better soon!

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.

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

That sounds like the correct dose of pyrantel. I don't know if Billy is not eating because of taking the pyrantel or not. Some diarrhea while treating for worms is expected. Unless the diarrhea is extremely water I would not overly worried about dehydration especially since he is drinking water. I would, however, be worried about a puppy that doesn't eat for longer than 48 hours. I suggest you call your vet for more advice.

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!

Poor Kai! I'm sorry to hear that he isn't feeling well and I understand your concern! In some puppies with a significant burden of roundworms, vomiting and diarrhea can occur as a means of expelling the worms. This also can cause inappetence from nausea and mild lethargy as a result. Although rare, intussusception (essentially intestines that telescope into one another) can occur in cases of parasitism, which can cause vomiting, lethargy and inappetence. At this point, monitor Kai for changes tonight and try to tempt him to eat with boiled white meat chicken and white rice as a bland diet. If he is still lethargic and not eating by the morning, he should be examined by his vet. The greatest likelihood is simply that his body is working to expel the roundworms.

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.
