Two dogs are sitting at the vets office. One has a dismal look about him. The other says, "Why the sad face?"

The other dog replies, "Well, my master beats the hell out of me all the time, and yesterday I had enough and I bit him. I'm next in line to be put to sleep."

After a couple of minutes, the second dog says, "What you here for?"

The first dog replies, "Well, my owner is this great looking gal you see. Yesterday she was putting my food out, and when she bent over, I could resist myself and started fucking her from behind."

The second dog says, "So you're next in line behind me?"

"No," said the other. "I'm here to have my nails done and see if they can do anything about my breath."
