he has been tested for worms, and had his scent glands cleaned already.

[QTPTootie]

He does it to dry it after he pees or to scratch it.

MAybe after he goes to the bathroom it sticks to him so he wipes it off on the carpet. Thats what my puppy did! :

[angel mommy]

I would say that his butt itches. Sometimes mine do that when they have some poop left on their butt or when their butt glands need to be expressed. Many dogs express their glands on their own by dragging their butts.

He may have a rash, infection, etc. My cat did this, and it was an infection, so the vet prescribed medicine for it, and it stopped.

[advice girl]

he might just do it for fun. because my dog has been tested and she still does it. She only does it when shes bored so that's what i think

[saz]

my dog does that aswell her glands are ok and she is upto date with worming. i think she just does it to clean her bottom or maybe she sometimes has an itch.
its not very funny when she comes in and has a bit off mess on her bottom and decides to clean it on my carpet, although she thinks it is.
i think some dogs just like to make sure they are clean.
my male dog had an infection of the anal glands and never scooted his bottom on the floor.

He's leaving skid marks on your floor.

He might be allergic to something, I suggest you take him to the vet so they can give him something to stop it.

There is some build up that is anooying him. To make him stop place him in your bathtub. Look at his butthole and sqeeze the sides of the butthole. Some liquid shud shoot out. If it does then he will stop. hope this helps
