My puppy has diarrhea with yellow mucus after eating peanut butter.

Pet's info: Dog | Goldendoodle | Female | unspayed | 5 months old | 27 lbs
My 5 m/o golden doodle puppy gets frequent bouts of diarrhea. Stool sample tests always come back negative. I've done some research online, and I think she may either have a food allergy or IBS. She didn't have diarrhea for the past couple of weeks because we put her on a bland diet and afterwards gave her only her regular kibble/treats. Now we tested to see if peanut butter would give a reaction and she ended up having diarrhea with yellow mucous. What might this be?

Some dogs are very sensitive to dietary changes without having true IBS or food allergies. If she does well on a bland kibble then I would recommend just being strict about no other treats. If she continues to have diarrhea the hypoallergenic diet trials would be something to consider. Also even considering biopsy of the intestinal tract at the time of spay may be something to consider in the future if this continues. I hope this is helpful!

It may be due to the peanut butter which should be stopped. withhold food for 8 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If the diarrhea does not resolve, take him to the vet to get treatment.
