Two women, each with a huge rotweiller, meet in the vet's waiting room. 

"What's up with him?", asks the first woman. 

"Oh I'm having him done, randy little bugger", replies the second woman. 

"Can't take him anywhere without him hanging on to peoples legs, or chairs or going after bitches". 

"I know what you mean, this one's even worse. 

Every time I bend over to get something out of the cupboard or out of the fridge, he jumps on my back having a go". 

"Are you having him done to?" 

"No. He's having his nails clipped"
