Experts get to the root of your dog's odd behaviour

Many dog owners have experienced that moment of embarrassment when, sitting in your living room with guests or your in-laws, your dog chooses that moment to 'scoot' across the floor, dragging his bum along the carpet.

Many people believe this behaviour is due to worms, but it is actually far more likely to be a different but entirely treatable problem.

A dog has two anal sacs positioned below their tail on either side of their bottom.

They release a smelly fluid when the dog goes to the toilet, acting as a scent marker.

This distinctive scent marks a dog's territory and identifies your pet to other dogs.

Healthy anal glands usually empty naturally when a dog poos.

However, problems can occur if the ducts, the narrow tubes leading from the sacs, become blocked.
