My 6-week-old puppy's stomach is bloated. Should I deworm him again?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 1 month and 15 days old | 10 lbs

I bought my 6 weeks old puppy a few days ago. The previous owner said that they already dewormed him 2 times and his 3rd wil be on September 16th. But my puppy's stomach is a little big for his size (looks like he's bloated) so i'm a little worried that he needs deworming right away. Should I deworm him again or wait for the day he needs to actually get it?

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Dewormers will treat different types of worms depending on which dewormer is used. If you feel Percy's stomach is bloated, you can get a fecal sample checked for eggs and which type, to determine if he has worms and what type. If he is eating and pooping and playing normally, you are safe to just wait and deworm on the 16th, however if he is vomiting, having diarrhea, or seems weak and tired, then I would get him checked by a vet and try a different dewormer. Best of luck with Percy!

    Yes, I would definitely see the vet to get another dewormer for Prince. It often takes at least two or more treatments in order to kill all the worms. Please give his vet a call to make him an appointment. I hope this helps!

    Hello. To make sure Pac is as healthy as possible, I would have him examined by a veterinarian as soon as possible. Your vet will take a stool sample from your puppy & look under the microscope for the presence of parasites invisible to the naked eye. The quicker you address this the less likely he will lose condition because of his bloating & diarrhea. Thanks for using Petco Pet Education Center, formerly Petcoach.

    The worms in Roxy's feces means the deworming treatment is working, and she will need another treatment into two weeks to kill all the worms. The bloated stomach is concerning, but it can be related to a heavy worm burden. To be safe, I would have her checked out by a vet in the morning if her stomach is still bloated. Best of luck.
