Pumpkin acts as a loosening agent when stools are too hard, or if your animal seems constipated. You can add a little more pumpkin to the food, about 2-3 tablespoons per meal for the average medium sized dog. Salmon oil and other essential fatty acids like Royal Coat EFA Express work very well to help soften hard stool and help it move through the colon and bowel.
If you find your dog has soft or looser stools, try feeding him a teaspoon to a tablespoon of canned pumpkin with each meal. Pumpkin is a fabulous natural remedy for soft stools or diarrhea. Plain canned pumpkin (not pumpkin pie filling), or steamed fresh pumpkin will help harden the stools back up.
If pumpkin is not available, cooked squash is a good substitute and can also be a bit more palatable. If you're noticing a more runny diarrhea or lots of mucous, fast your dog for 12 to 24 hours. This will help your dog's gut heal and he'll often be fine after this.
Continue this for a few days, until the stools normalize, then gradually transition him back to his regular food. Small frequent meals will help the gut digest while not causing further trauma.
Dogs should be having at least one bowel movement daily. If they don’t, they could end up with chronic constipation problems. If your animal is constipated for more than 2-3 days, contact your veterinarian for advice. In cats especially, constipation can lead to mega-colon, a difficult and painful disorder.
