It comes in multiple flavors and varieties, which makes it easier to match your dog’s preferences. The wet versions are easier to digest thanks to the higher moisture content.

- L-carnitine helps maintain healthy weight
- EPA and DHA support healthy skin and coat
- Exclusive kibble shaped for small dogs
- Enhanced palatability for fussy eaters
- Meets high energy needs of small breeds
Cons
- Kibble may be too large for dogs under 9 pounds

- Contains corn and gluten meal, which some owners prefer to avoid
This is a dry food formulated for small breeds ten months and older. It contains 3,812 kilocalories of metabolizable energy per kilogram, or 343 kilocalories M.E. per cup on an as-fed basis.
The high dietary fiber content makes it well suited for dogs with abnormal stools or colitis. It can help reduce gas and stomach gurgling fairly quickly after the transition period.
Compared to most standard dog foods, it sits near average for protein, fat, and carbs, which suits dogs that don’t need an extreme formula. Animal protein is the main source, with a moderate amount of named by-product meal.
It supports nutrient absorption and gut flora, which is why it’s designed specifically for sensitive stomachs. Smaller dogs tend toward constipation while larger dogs lean toward loose stools, and this formula is sized and balanced to work with your dog’s digestion rather than against it.
Split meals into smaller, more frequent servings rather than one large feeding. Good stool quality is the clearest sign the food is working as it should.

If you’ve already tried several foods without success, this is one of the stronger options for GI issues. It’s built around healthy stool quality, using an optimal prebiotic blend to get there.
Dietary fibers, both soluble and insoluble, help soothe and cleanse the digestive tract. Proteins and prebiotics work together to maintain gut flora at a healthy level.
DHA, omega fatty acids, fish oils, and EPA support GI tract function. The ingredient combination is aimed at reducing diarrhea, vomiting, and lack of appetite.
The low-fat formula keeps nutrient absorption running efficiently, and antioxidants help the immune system stay strong. The diet contains 910 kcal M.E./kg, 350 kcal M.E./can on an as-fed basis.
It’s a decent choice for underweight dogs who need calories but can’t handle rich food. Mix it with dry food if needed, and always serve in small portions to support smooth digestion.

The formula includes Blue’s exclusive LifeSource Bits, a precise blend of antioxidants, vitamins, and minerals designed to support immune health and oxidative balance. Main ingredients are barley, pea fiber, chicken meal, brown rice, and deboned chicken.

Canine Caviar is a good option if you have a puppy with colitis. It’s formulated for all life stages, so you won’t need to switch foods as your dog grows.
It’s free from fillers and grains, and the alkaline-based recipe contains no gluten. The alkaline approach supports a proper pH balance, which helps oxygenate the blood and reduce cellular degeneration.
An alkaline diet is thought to support overall longevity and quality of life. It mirrors the kind of food a dog might naturally seek out, and the formula is said to reduce issues like tear stains, shedding, and scratching.

Final Thoughts
Colitis in dogs is stressful for both pet and owner, but the good news is that diet is one of the most powerful tools you have for managing and easing it. Pairing the right food with a thoughtful feeding schedule and adding a quality probiotic-rich dog food option can make a real difference in your dog’s gut health and recovery.
Nutrish Real Chicken and Veggies leads this list as a gentle, highly digestible option that delivers real protein without the heavy fillers that can aggravate a sensitive gut. If your dog needs something more clinically targeted, Royal Canin Gastrointestinal Low Fat is a veterinarian-trusted formula specifically developed for digestive conditions.
Smaller, more frequent meals tend to work better for dogs with colitis than one large daily feeding, and keeping your dog well hydrated supports the digestive system throughout recovery. Regular vet check-ups are equally important since colitis can sometimes have an underlying cause that needs professional attention.
With the right food and a little consistency, most dogs with colitis see meaningful improvement over time. Use this list to narrow down your options and work with your vet to find the formula that fits your dog best.
