Scooting, licking and a fishy smell usually point to the anal glands. This article explains what these glands do, why they get blocked, what you can safely do at home, and the warning signs of impaction, infection or an abscess that need a vet rather than a home fix.
Scooting, excessive licking under the tail and a fishy odour usually mean the anal glands are full, irritated or infected. Many cases ease with a higher-fibre diet and a vet check, but a swollen, red or leaking bottom needs veterinary care. Don't attempt to squeeze the glands yourself unless your vet has shown you how.
Scooting, licking and a fishy smell usually point to the anal glands.
Dogs have two small scent sacs just inside the anus, at roughly the four and eight o'clock positions. Each firm bowel movement presses on them and releases a few drops of strong-smelling fluid, which is why dogs sniff each other's rear ends. When stools are soft, or the ducts are narrow, the glands don't empty and fluid builds up.
The classic sign is scooting, dragging the bottom along the floor or grass. You may also see persistent licking or biting under the tail, a sudden fishy smell, a reluctance to sit, or a tender, swollen area beside the anus.
Scooting is the classic sign of full or irritated anal glands.
The safest home step is dietary. Firmer, bulkier stools help the glands empty on their own. Ask your vet about adding fibre, whether through a prescription diet or a supplement, and keep your dog at a healthy weight, since excess fat around the area worsens the problem.
Firm, bulky stools help the glands empty naturally; fibre often helps.
Many owners are tempted to squeeze the glands at home, but done wrongly this can bruise the delicate tissue and make things worse. Routine expression is best left to a vet or trained groomer, and healthy dogs shouldn't need it at all. If your dog needs frequent expression, ask your vet to look for the underlying reason rather than treating it as normal maintenance.
Does every dog need their glands expressed?
No. Most dogs empty their glands naturally with firm stools and never need manual expression. Routine squeezing of healthy glands can do more harm than good.
Can diet really fix scooting?
Often, yes. More fibre creates firmer stools that press on the glands and empty them naturally. It won't fix an infection or abscess, which still need a vet.
Is scooting an emergency?
Occasional scooting isn't, but a red, swollen, painful or leaking bottom is. If you see blood, pus or a lump, book a vet visit quickly.
Why does my dog's bottom smell fishy?
That distinctive smell is anal gland fluid. A sudden strong odour usually means the glands are overfull or leaking and should be checked.
