My 6-weeks old puppy took meds for deworming 4 hours and he still hasn't pooped. I also already fed him. Should I be concerned? How long does it take for a puppy to poop after deworming?

Hello, sorry to hear about Max. It does appear like there are worms in his stools. Depending on which dewormer you administered it can cause a rapid kill of a high burden of worms which could cause pets to become constipated. As long as he does not have any vomiting, lethargy, abdominal pain, or loss of appetite then you can continue to walk him regularly and offer plenty of water. If you note any of these sings, then he should be evaluated sooner. Hope this helps and best of luck.

I am sorry to hear about Paige! If she is otherwise acting normally (normal energy level, eating and drinking normally, no vomiting) then I wouldn't worry just yet. I would try giving Paige some exercise by walking her, as exercise can often stimulate bowel movements. You can also add a teaspoon of canned pumpkin to her food to increase her fiber intake. You can attempt to take her temperature by inserting a thermometer rectally one to two inches after lubricating it with vaseline/ ky jelly/ or other lubricant. A normal temperature is 100 to 102.5. This way you can ensure there is no fever, and often the action will stimulate a puppy to have a bowel movement. If she still is not having a bowel movement tomorrow or she develops vomiting/lethargy/decreased appetite then a visit to the vet is recommended.

It could be that Max has a severe infestation with worms, and that is why you keep seeing worming in his feces. I would give him a third deworming treatment in 14 days after the second one. Should he still continue to have worms after this third treatment, then I would have him seen by a vet.

Because of the life cycle of worms, it takes at least two deworming treatments given two weeks apart to kill all of them. The first kills the adult present, while the second kills the worms that had not yet hatched from eggs at the time of the first treatment. You will need to give Marley another deworming treatment now, and another one in two weeks. After that, she should be given a deworming treatment once a month until she is six months of age. She should then be given a deworming treatment every three months thereafter. I hope this helps.
