Two dogs were sitting in a vet's office. The bigger of the dogs gruffs, "Whatcha doing here?"
The little dog responds, "I'm getting 'fixed'. Whenever I see my mistress I get so horny I just jump on her leg and start humping."
The first dog says, "Yeah, I know what you mean. Once my mistress had just got out of the shower, and she bent down to pick up her clothes, and I couldn't resist it.. I jumped up and starting taking her from the rear!"
The second dog exclaimed, "Wow! So you're here to be fixed too?" "Hell no, I'm getting de-clawed."
