The poop scoop: Dog digestion myths debunked

As pup parents, we spend a lot of time handling dog poop, and as a key indicator of a dog’s health, it’s only fitting that we think and talk about it just as much. Unfortunately, what happens at the dog park doesn’t always stay there, and what you may think you know about your dog’s digestive health may actually be a load of…fiction. In this article, Ollie debunks the myths and common misconceptions.

MYTH: If my dog is pooping consistently, everything’s OK.

While regular pooping is a good sign, it’s not the only indicator of digestive health. You should also monitor:

Stool consistency, color, and volume
Presence of mucus, undigested food, or foreign materials
Frequency changes, straining, or signs of discomfort

These details can help detect issues like food intolerances, GI inflammation or nutrient malabsorption—well before other symptoms appear.

MYTH: Kibble is as easy to digest as fresh food

Kibble often contains processed ingredients, fillers, and low moisture, which can slow digestion. Fresh food tends to be more bioavailable—meaning nutrients are easier to absorb. However, digestibility also depends on the specific formulation and ingredient quality of either option.

MYTH: Finding vegetable pieces in stool is a sign of improper digestion

Not necessarily. Dogs lack certain enzymes to break down plant cell walls, especially insoluble fiber (like in carrots or corn kernels). Small visible bits in stool can be normal, particularly from raw or minimally processed veggies. However, excessive undigested matter could signal a need for:

Improved digestive enzyme support
Investigation into malabsorption

MYTH: Mucus in poop is always a bad sign

Not always. A small amount of mucus can be normal, as it helps lubricate the colon. However, persistent or excessive mucus, especially with diarrhea, blood, or straining, may indicate:

Inflammation (colitis)
Gut microbiome imbalance
Food allergies or parasites

Veterinary evaluation is warranted if mucus is frequent or accompanied by other symptoms.

MYTH: Small poops are a sign my dog isn’t eating enough

This is misleading. Smaller poops can actually be a sign of high nutrient absorption and food efficiency, which is common with fresh or raw diets. Larger poops, particularly if frequent and bulky, may indicate that the food has high filler content or low digestibility. It’s less about volume and more about quality, consistency and overall GI health.

MYTH: All food transitions cause diarrhea

Not true. Diarrhea is common during abrupt changes, but well-managed transitions (over seven to 10 days) often prevent issues. Signs of diarrhea during transition could also point to:
