My puppy has soft, grey stool. Is it EPI, and when should I see a vet?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 2 months and 24 days old | 15 lbs

My 11 wo Border/Aussie has just started to have soft, grey stool. It isn't always grey, but last night and this morning it was. I did some googling and it said it may be EPI... I don't want to overreact and take him to see an ER vet right away if it's not serious, but how long should I wait to see if this is just him eating his food too fast, or if it is possible EPI?

EPI generally not an emergency at this stage and there are other causes of stool discoloration.
I recommend to have Myles seen by his normal veterinarian (as long as he seems normal/happy) and have the stool checked for parasites and bacterial over growth. The doctor may recommend treatment based upon the results and then you wait and see how things okay out.
I do recommend to feed pets a highly digestible diet such as Royal Canin. I have seen many puppies with bowel abnormalities that normalize eating this diet.
EPI does typically present as a greyish stool with a shiney coating (that’s the fat in the stool). The pets also usually are slow to grow and gain weight poorly. If this is suspected, your doctor will testing to diagnose the condition.
I hope this is helpful and please feel free to post any further questions.
