oh licks herself sorry ignore my post then.

Do what?

Oh god, I may have read the OP's post wrong and my post should be ignored!

I saw licking and dog and hair removal in the same sentence and just assumed it was the same type of problem I had experience with. Lols.

some small dogs do this as a type of nervous habit, one of my dogs does the same. other than this nuisance, it is a healthy dog (no real pests-parasites in my area).

my dads dog had this kinda problem, he would constantly lick and chew his paws so bad they would be raw and bleed, for years we COULDNT GET HIM TO STOP. and then he started licking and chewing in the armpits of his back legs

then he started getting really dry skin around his legs and we found out its actually a skin disease of some kind ( i cant remember what its called ).

BE CAREFUL THIS ISNT HAPPENING TO YOU AS IT CAN BE FATAL FOR YOUR ANIMAL.

Dogs have two noses.

One external and one internal, which is located on the roof of their mouth.

When they lick they are depositing scent into that second nose.

IMHO, it's a pretty decent idea.

All of this information was brought to you by a guest that appeared on NPR.

that doesnt explain why the dog is ripping its own hair out

is she well exersised? alot of dogs will get obcessions due to not enough exersise as an outlet for pent up energy

a muzzle or a bucket on her head for a bit

ROFLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL
