A healthy dog can often go 24-48 hours without a bowel movement, but if it's been more than 48 to 72 hours (2-3 days), you should see a vet, especially if they're also straining, vomiting, lethargic, or not eating, as this can signal serious issues like blockage or dehydration, warns Dr. Buzby's ToeGrips for Dogs, PetMD, Woofz, GoodRx, Blue Cross, AKC Pet Insurance, and VEG ER for Pets.
