3 dogs, a Doberman, a Boxer and a German Shepard are sitting in a vets office and strike up a conversation.

The Doberman turns to the Boxer and asks, what are you here for?
"I'm a pisser", "I piss on everything", the sofa, the cat, the kid but the final straw was last night when I pissed in the middle of my owners bed.

So, what is the vet gonna do? the Doberman asks.
"Lethal injection" came the sad reply from the Boxer.

The Doberman turns to the Shepard and asked the same question.

"I'm a digger", I dig under fences, I dig up flowers and trees. I dig for the hell of it. When inside I even dig up the carpets, but I went over the limit when I dug a hole in the middle of the owner's couch.

So, what they gonna go to you? "Lethal injection," replied the dejected Shepard.

The Shepard asked the Doberman why he was there.

"I'm a humper. I'll hump anything, I'll hump the cat, pillows, the table, fire hydrants. Whatever. I want to hump everything I see. Yesterday, my owner had just got out of the bath and bent down to dry her toes and I couldn't help myself and hopped on her back and started humping away.

The Boxer and Sheppard exchanged a sad glance and said, "So, lethal injection for you too, huh?"

No, No, the Doberman said. "I'm here to get my nails clipped."
