Why is my puppy sick after eating a new treat with peanut butter?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 6 months and 29 days old | 50 lbs

My puppy woke me up at 7 this morning whining to be let out of the cage, but before I could get to her she had a diarrhea accident. She fell back asleep for a bit and when I woke her up to get some breakfast she didn’t want to eat and only had a little bit of water. She’s pretty lethargic as well. Yesterday I gave her a new treat with some peanut butter to keep her entertained for a bit while I was gone. She’s never had either before, could this be a bad reaction to the new treat?

It could be this new treat has upset Harley's stomach. I can give you a home remedy for him to see if that helps. Withhold food for 12 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. I hope this helps!
