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 Kush could have tapeworms, which require praziquantel to treat. That is a prescription medication. Since he won't eat, I would take him into a vet first thing in the morning. Best of luck.

    It is normal to see some diarrhea with dead and alive worms after giving a deworming treatment, but anorexia isn't as common. It could be that his stomach is really upset from the deworming treatment and the movement of the dead and alive worms. I would try to tempt him to eat with some boiled white meat chicken (no bones) and white rice in small amounts several times a day. If he still refuses to eat tomorrow, then I would have him seen by a vet.

    Poor Link. It sounds like he likely had a very large burden of worms. I would try to get him to eat some plain chicken and rice. Sometimes they won’t eat their regular food when they don’t feel well but you can sometimes entice them to eat homemade meals. If he is still not eating then yes, I would have him rechecked. My biggest concern is that he will quickly get dehydrated or that something more serious is going on. Your vet will be able to determine his hydration status and give him fluids if needed. Your vet will also be able to look st him and do additional diagnostics if needed to determine if something more serious is going on. I hope this helps and he starts feeling better!
