Short answer: the most common cause of scooting is a buildup of fluid in the anal glands, creating itching or discomfort — in this case, having the glands expressed is what's needed.
Why do dogs scoot their bottom?
When fluid builds up in the anal glands located on either side of the anus, it creates pressure and itchiness, and scooting the bottom along the ground is an attempt to relieve that.
How can I tell if it's an anal gland issue?
If there's a fishy smell around the rear end, or your dog reacts sensitively when the tail is touched, the anal glands are likely full.
Are there other causes besides the anal glands?
Parasitic infection or skin irritation around the anus can trigger similar behavior too. If you see parasites in the stool or the skin looks red and irritated, these possibilities should be checked as well.
Can I express the anal glands myself at home?
It's possible if you know the correct technique, but if it's your first time, it's safer to learn the method from a vet or groomer before attempting it yourself.
What signs mean I should see a vet?
If the area around the anus is significantly swollen or red, or if the discharge has blood mixed in, it may have progressed to anal gland inflammation and needs veterinary care.
