Why is my puppy's rear swollen, constipated, and painful when pooping?

Updated On September 23rd, 2025

Pet's info: Dog | Pomeranian | Female | spayed | 4 months old | 2.425 lbs

My puppy is still swollen on the butt and is constipated and will scream when going to the toilet. She is very vocal though and screams a lot even when she’s scared over something really silly( a certain object moving/making noise, vets touching her etc) she is very anxious and will just scream quite often which is the only reason I’m not overally concerned and assuming it’s just due to being a bit sore but just wanting confirmation. The vets know about it but I forgot to mention the screaming

Hi there and thanks for posting on Petco Pet Education Center, formerly Petcoach! She may be experiencing pain or discomfort while defecating and this can occur for a variety of reasons. Swelling around the anal region could be an indication of an impacted or infected anal gland. The constipation you describe could be due to lack of fiber in the diet, eating something out of the ordinary, or perhaps an infectious cause such as an intestinal worm infection. If Mila has not seen her veterinarian for this yet, I would recommend this happen soon. Her veterinarian may recommend an exam, anal gland expression, and fecal test to help determine a cause so she can be treated appropriately. I hope this helps!

    Is the stool soft, diarrhea or very hard? I would recommend getting Loli's anal glands expressed. If he is scooting that is most likely bothering him. Depending on what is going on with his stool would depend on what type of treatment your veterinarian would do. I would recommend a stool sample be performed to look for intestinal parasites. Thank you for using Petco Pet Education Center, formerly Petcoach.

    Without actually examining the puppy, it is difficult to know the cause and the best way to treat. If he is otherwise acting normal then you can monitor him and see if it resolves. Otherwise, he needs to be examined by a vet to determine the cause and treat. He could have a parasite, infection, or a congenital malformation.

    Hi there. Any time puppies exhibit this behavior I do a couple of things-first repeat the fecal and make sure there were no organisms missed on the first one. Secondly that their anal glands are not so full they are making going to the bathroom uncomfortable. If these two do not alleviate the cause I take x rays to rule out a foreign body, etc. your veterinarian can check all of these things in a pretty routine visit. I urge you to take Winston in for a check up especially if his pain persists-if it is his glands they can rupture which is much more painful. I hope this helps!
