Why Can’t Dogs Digest Fur?

1 Overview

Where does the fur come from? Why can cats vomit it but dogs can’t? Today we dig into the fur dogs swallow.

This common fur slips into the gut unnoticed – shed hairs and more. Let’s detail the usual routes.

Poor grooming

All dogs shed; long-haired ones accumulate more. Short-haired are better but still need regular brushing.

How does shed fur get in? It floats in air, lands in the bowl, or enters as the dog licks itself.

Too little exercise

Every dog needs daily exercise, not all-day confinement.

An under-exercised dog gets bored and licks itself, and fur goes in.

Too little sleep

Rare, but possible.

Without enough sleep the dog is restless and, like when bored, chews and licks itself – especially the paws – to release stress.

External parasites

Everyone knows fleas and lice harm.

Parasites make a dog want to nibble and itch; nibbling, fur slips in. So regular parasite control matters.

Over-licking

Occasional licking is fine.

But as a compulsion, fur enters by mouth. Many causes – winter dry skin itches, the dog licks madly; if missed, the habit lasts into summer.

These are just common cases; many are unforeseen, like swallowing another dog’s fur at play. So know this:

More fur means water is soaked up by it, leading to dehydration and lost appetite.

The dog also gets diarrhea, constipation, sleepiness, vomiting, and may cough like a cat with a hairball – but can’t bring anything up.

Now the key topic: another major route of fur intake.

Treats made of animal tissue, like rabbit ears.

Should you feed rabbit ears? Not that they’re unsafe, but the fur worries. Sellers say the fur aids digestion; others say it does nothing and can block the gut.

Rabbit ears are a great low-fat, mostly-cartilage treat, so no worry about intestinal blockage.

But judge the fur on rabbit ears from several angles, not one.

First, a little rabbit ear: its fur, hardly absorbed, sweeps the gut and stimulates movement – the aids digestion sellers cite.

But a small, low-exercise, weak-gut dog hardly gains that benefit.

And too many rabbit ears or furry foods will pile fur in the gut – no doubt.

Local sellers want to sell more, but foreign makers advise: 2-3 a week for medium-large dogs, 1 for small.

Why do some dogs get diarrhea and others constipation from fur?

It depends on digestive ability; each dog differs, so symptoms differ.
