Does anyone else find it peculiar after a dog pees, the dog uses its hind legs to "cover" it?

Yes. same here, though I have cat. but my cat does similar. I hate it though. because he keeps trying to cover his pee from the wrong place. instead of covering using the sand. he pulls nothing from the floor, or wall. or anything near the litter box. so he scratch, scratch, from the floor, then he checks his pee, it is still there, so he repeats and repeats (annoying sound) . then later he turns and put real sand.

There are quite a few issues which could help alongside with actual therapy, commence rotating the leg and additionally employing small volume of tension to the backside of the foot. could additionally do hydro-therapy ( swimming ) do not do any of those issues merely before speaking on your veteriarian because of the fact it could do greater harm than good based on the surgical operation achieved and the dimensions of time because of the fact it became into achieved. wish this helps.

It's something to do with scent marking their territory.

I used to have a dog that would kick his hind legs like that when he saw another dog. He'd kick up a storm instead of barking. I wonder why.

My Big Woof never did it until he saw another dog do it. Now he is too old to care.

Better than using it's mouth...no doubt...
