Where I live their are two sisters in their late 60's.  One of them, with her husband own a male Shitzu named Rupert, which a biker friend of mine said was the biggest caterpillar he had ever seen!!!  Anyway the other sister and her husband were taking care of the dog while its owners were away on holiday.  The sister was grooming the dog and thought my goodness he has ticks and I better remove them.  She decided to email her sister about doing this and after explaining where the ticks were, got this response "Don't you dare, those are his nipples!"
