My Chihuahua is rubbing his rearend across the carpet and is very "sensitive" about that half of his body. I was told there is a gland that fills and that is their way of releasing the fluid...I am taking him to the vet after the holiday...does anyone know about this subject?

Yes, it's true. Sort of. Dogs do have anal glands located just inside the anus. They secrete a very smelly liquid. Usually these glands (or more correctly sacs) express when the dog has a bowel movement, but not always, especially in small breeds. When they don't empty naturally they can cause a great deal of discomfort, and may get impacted/infected. The dog will "scoot" in an attempt to empty them. If they become really painful, the dog will get crabby about having the rear half of his body touched.

But anal sacs are not the only reason a dog may "scoot". Tapeworms can cause scooting. Allergies, particularly food allergies, can make the anus itchy, and cause scooting, too. But most of the time, it's the anal sacs.

sorry i can't help you any type of information but here has many friends they can do that.thanks.

First off, welcome to the forum. Glad to have you.
Secondly, what vetgroomer says is true. My dog also sometimes has problems emptying my sacs and he will often try scooting across the carpet, or even cement or gravel (OUCH!). So we have to take him to the vet every few months to have them empty them. We asked what we could do to help it. She told us that there was a surgery you could do to remove them, but we didn't really want to have to to that. She also said that feeding my dog foods that are high in fiber would firm up his stool and it would to help to empty the sacs when he poops. So whenever he is having problems with his anal sacs we feed him a cup of canned pumpkin with dinner and it does help a bit. Just thought I would put that out there for you to try. Sorry I was slightly rambling, I hate just stating things.

Thank you all for the replys...to the vet on Monday to have those glands checked!
