Digger, Pooper and Humper

Three dogs are sitting near each other at the veterinarian's office. The first dog looks at the second dog and asks "What are you here for?" The second dog replies "I'm a digger. I dig up flower beds, gardens and the lawn. The other day, I was napping in my master's leather recliner. Had a bad dream and I shredded his cushions. Now I'm here to get neutered. What are you here for?" The first dog answers "I'm a pooper. I poop everywhere. Can't help it. I was sleeping in my master's bed and had an accident. Ruined the satin sheets. So, I'm getting neutered too." They look over to the third dog and ask "What's your story?" The third dog answers "I'm a humper. I hump everything. You name it, I've humped it. The other day, I was passing by the bathroom as my master was getting out of the shower. When she bent over to towel her feet, I humped her. Couldn't control myself." The second dog asks "Are you getting neutered too?" The third dog answers "Nope, just getting my claws trimmed."
