Dog diarrhea after lamb leftovers & diet change. Vet or home?

Updated On September 23rd, 2025

Pet's info: Dog | Doberman Pinscher | Male | unneutered | 3 years and 6 months old | 90 lbs

I roasted a lamb and had a lot of leftovers so I fed my dog only lamb for 3 days. He seemed more than happy but once I switched him back to his regular diet he has had diarrhea. He goes more frequently and his stool is very thin liquid. He's not lethargic and still has an appetite but its been 4 days and he still has diarrhea. Is there anything I can do or should he see a vet?

The abrupt back and forth change in his diet is likely what caused the diarrhea. I would fast him for 24 hours, making sure to provide plenty of fresh water. When you resume feeding him, offer small amounts of plain boiled chicken breast or hamburger, no seasoning whatsoever with plain boiled white rice. Offer him a small amount several times a day, then gradually transition him back onto his regular food, starting with 1/4 regular food to 3/4 rice mixture, then the next day 50//50, then 75/25, until you have him back on his own food again. In the future, I recommend not feeding him so many leftovers, instead, a small amount as an occasional treat would be better. If at any time he starts vomiting, the diarrhea does not resolve, if he becomes lethargic or suffers any other adverse symptoms, get him in to see your vet right away.
