My dog strains, soft poop and mucus come out. Is he constipated?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | unneutered | 5 months and 29 days old | 33 lbs

Hello! My dog is having poop problems. His poop is usually soft but in the past few weeks it has become extremely soft (like yogurt) and for the past few days he has been doing something weird. When I take him out he will scrunch up like he’s pooping but only a few drops of a mucus type substance and maybe one tiny sliver of soft poop will come out, then he just stands there scrunched up for like 3-5 min with no poop coming out. Also, he asks to go out to “poop” constantly now! What should I do?

It sounds like your dog may be seriously constipated and the only material that can get by is soft stool. I strongly recommend Finn be seen by your vet as soon as possible. Hard stool building up in the colon stretches it out of shape, and it also causes stretching of the muscles around the anus, causing perianal hernias that trap the collected feces, effectively making a plug. Your pet may need more than one enema and even manual extraction of the feces in order to relieve this episode. To help avoid this in the future, you can add Miralax to the food. Miralax is a very gentle, easy to give treatment for constipation, available over the counter at any pharmacy. The dose of Miralax is 1 tsp per 50 lbs mixed in with food once a day. You can also add a tablespoon of vegetable or olive oil to his food once daily, or add a couple of teaspoons of canned pumpkin (not pie filling) to his food daily.
