My puppy is weak with diarrhea after deworming. How to support?

Poor pups. While a heavy parasite load can cause severe GI upset, and anemia which can cause a pup to become extremely lethargic, have bloody diarrhea, etc, I would also want to rule out underlying illnesses as a possibility. It would be best to bring them to a vet ASAP especially if they are lethargic or unable to keep any food or water down as puppies can quickly become very dehydrated. They may also need supportive care such as an IV or injected medications if they are very ill from the parasites or other causes. You can try continuing to offer water, or rubbing a little honey on their gums for energy until you can get to the vet, however due to the severity of symptoms it would be best to seek emergency care.

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.

These signs could be compatible with a colitis, which is an inflammation of the last part of the colon possibly secondary to the parasite infection, usually related to dietary indiscretion. As a first approach, I would suggest to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice vomiting, lethargy or inappetence.

Apparently the earthworm protein is not compatible with your dog's digestion. I suggest you take him off all food for 12 hours and then feed him boiled white rice with boiled white boneless chicken in small quantities over several feeds a day. Do this for 2 days, then slowly transition back to his normal dog food over two or three days. By then the diarrhea should have stopped. Make sure he has plenty of water available at all times. Should he deteriorate or should the diarrhea get bloody, you will need to take your dog to a vet for an exam and treatment,

Oh no, poor Fat Boy! You are correct that worms could be causing the diarrhea, but if he was being starved, the sudden change in diet could also be causing the diarrhea. I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. With the deworming, he will need another deworming treatment two weeks after the first to kill all the worms. After that, he should be dewormed every three months.

Yes, deworming tablets can cause some diarrhea in puppies, but it could also be due to the dead worms moving through Hunter's intestines. Given that he has just recovered from diarrhea, I recommend waiting another week before giving him the next deworming tablet. It's fine to deworm him every two weeks until he is 12 weeks of age, then he should be dewormed monthly until six months of age. After that, he needs to be dewormed every three months. Good luck, I hope this helps!

I can’t think of a way that this would be related to the most common broad spectrum dewormers that we use but it would help to know what kind exactly. She may have low blood sugar or an infection. It sounds like she was moving better before today, but if not some puppies have abnormal leg muscle formation and it might be something like this (swimmer puppy). If she hasn’t been eating well, if you’ve seen vomiting or if she seems disoriented you should rub some honey on her gums and see if you can find an emergency vet somewhere. Otherwise head to a vet in the morning.
