Why Does My Dog Drag His Butt?

Their are two most common reasons.

One, they glands back there they are rubbing.

Two, they have worms!
So look at there gums! Are they pink or pale?

If you saw pale I would weigh the dog, and then go to the Feed Store not the VET! ( You need that money more than him! ) And ask for TWO worm pills for a dog that weights X.

Go home and don't feed the dog anything especially MILK PRODUCTS!

Then open his mouth and put one dose down his throat and shut his mouth fast and hold it shut!

Then blow real hard in his nose until he swallows.

Then put him out side and don't feed him Diarrhea is around the corner, and lots of worms, too!

Wait 10 days and repeat it again.
