Quick answer: Most mild dog diarrhea resolves at home within a day or two. Rest the gut with a 12–24 hour fast (healthy adult dogs only, not puppies), then feed a bland diet of boiled chicken and plain white rice, keep fresh water available, and slowly return to normal food over 3–5 days. Call your vet if the diarrhea lasts more than 48 hours, contains blood, or comes with vomiting, lethargy, or a painful belly.
Hi, I'm Preston Smith, co-founder of Bully Sticks Central. Diarrhea is one of the most common reasons dog owners email us, usually asking whether a treat caused it or how to settle their dog's stomach. Here's the plain-English version of what actually helps.
Why does my dog have diarrhea?
Loose stool is a symptom, not a disease. The usual culprits are a sudden diet change, eating something they shouldn't have (garbage, table scraps, or a new treat introduced too fast), stress, parasites, or an underlying illness. According to the American Kennel Club, most short bouts are self-limiting and clear up on their own. The job at home is to support recovery and watch for the signs that mean it's time to see a vet.
How do you treat dog diarrhea at home?
1. Rest the gut with a short fast
For a healthy adult dog, withholding food for 12–24 hours gives the digestive system a chance to calm down. VCA Animal Hospitals notes this can help, but never fast puppies, seniors, or dogs with other health conditions — they need steady nutrition. When in doubt, skip the fast and call your vet.
2. Feed a bland diet
Once you reintroduce food, start bland: boiled, skinless chicken breast with plain white rice, in small, frequent portions. No butter, oil, or seasoning. A little plain canned pumpkin (not pie filling) can add gentle fiber. Feed this for two to three days until stools firm up.
3. Keep water flowing
Diarrhea drains fluids fast, and dehydration is the real danger. Keep fresh water available at all times. If your dog won't drink or you notice tacky gums, sunken eyes, or low energy, that's a vet call.
4. Transition back to normal food slowly
Reintroduce their regular food gradually over three to five days, mixing in a little more each day. Rushing back to full kibble is one of the most common ways owners end up back at square one.
When should diarrhea send you to the vet?
Home care is fine for a mild, one-off bout. Call your veterinarian if you see any of the following: diarrhea lasting more than 48 hours, blood or a black tarry appearance, repeated vomiting, obvious pain or a bloated belly, signs of dehydration, or any diarrhea in a young puppy, senior, or a dog with existing health problems. The ASPCA notes that persistent or bloody diarrhea can signal something more serious that needs testing.
Can the wrong treats cause diarrhea?
Yes — and this is where a lot of owners get tripped up. Treats loaded with additives, artificial ingredients, or fillers can upset a sensitive stomach, and rawhide is a frequent offender because it doesn't digest well. That's exactly why we built Bully Sticks Central around single-ingredient chews. Our bully sticks are 100% natural, 100% real meat, fully digestible, and contain no rawhide — ethically sourced from grass-fed American and Argentinean farms and 100% high-quality guaranteed.
Once your dog's stomach has settled and they're back on normal food, introduce any new chew slowly, one at a time, so you can spot what agrees with them. If you want a gentle, digestible option, our beef trachea chews are another single-ingredient choice that's easy on the gut.
The bottom line
Most dog diarrhea is short-lived and responds to rest, a bland diet, hydration, and a slow return to normal food. Keep an eye on the warning signs, don't hesitate to call your vet when something feels off, and once things are back to normal, stick with clean, single-ingredient treats your dog can actually digest.
