Short answer: Most dogs scoot because their anal glands are full or impacted. Less common causes include tapeworm segments, allergies, perianal skin infection, and rectal masses (more likely in senior dogs). If scooting persists more than 2 days, see your vet.
What you should actually do
- About 4-12% of dogs have chronic anal gland problems – small breeds are over-represented.
- A high-fibre diet + a quality kibble can normalize stool firmness and reduce impactions.
- Allergic dogs scoot from itch, not anal glands – rule out food + environmental allergies.
- Look for rice-grain tapeworm segments before assuming it’s the glands.
- Persistent or bloody scooting in a senior dog: ask the vet to feel for a perianal mass.
The ‘bum scoot’ is one of the most universally Googled dog behaviours, and most of the time the answer really is anal glands – two small scent sacs at 4 and 8 o’clock around the anus that normally empty when the dog passes a firm stool. When stool is too soft, the glands don’t get squeezed and slowly fill, then become uncomfortable, then become impacted, and finally abscess. The fix at the early stage is firmer stool: a high-fibre supplement like psyllium or pumpkin, or an over-the-counter anal-gland supplement like Glandex. At the impacted stage, you need a vet or groomer to manually express the glands.
Don’t miss the alternatives. A dog who is scooting plus has tapeworm segments visible on the stool needs praziquantel (and flea control). A dog with seasonal itch + ear infections + scooting probably has atopic dermatitis and is itchy around the perineum, not full glands. And a senior dog with progressive scooting + visible mass + increased thirst could have an anal sac adenocarcinoma – rare but serious enough to always check.
