My 3-week-old puppy has a bloated belly but good energy. What's wrong?

Updated on September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Female | 22 days old | 1.1 lbs

I had a litter of six. They are 24 days old. There is one that is half the size of the others but good eating and good energy. I am concerned about her belly as it is always bloated. They were wormed at 2 weeks for three days. She has no blue ting to mouth or nose and does not seem to be struggling to breathe. It looks like ascites. Do you have any ideas? My vet is out of town for another week and it does concern me.

If her breathing is normal and gums are normal pink, then there is a good chance this is just a worm overload. Sometimes it takes 2 treatments done 2 weeks apart to get rid of worms in young puppies. Ascites would almost always cause a pet to be lethargic and act ill. As long as her energy is good and everything else is fine, it is ok to monitor her for now and have your vet check her for parasites when they get back out of town. If she seems ill at any point, then its best to take her to another local vet for a check up.

Best of luck with your young puppy Lady Jane moving forward. Take care. : )
