I was looking at a dog breeder's ad for a pure breed pup they were trying to sell (hey, I was just looking! I am not getting another pup! :>> ) and the breeder is insisting the purchaser of the dog agree to a no breeding clause whereby the owner will have the dog sterilized and not use the dog to breed.

I sezs to Mr...'just how can the seller (breeder) insist the buyer adhere to this condition?'

Mr sezs the seller can not enforce this.

I agree.

But why would they insert that clause if they can not legally enforce it?

Bizarro world now isn't it?
