I would agree STRONGLY with what has been said already about Peke overbreeding. Yes there are too many Pekes around but the real point about the overbreeding is that they have been, as a breed, bred too genetically similar to each other. Responsible breeding is the only way out for so many popular breeds. Kennel Club standards (worldwide) have encouraged breeding practices that shrink the genetic diversity in so many breeds ( a bit like cousins and siblings breeding in humans!). This leads to a less healthy gene pool and common defects that are usually killed off in a more natural setting become the normal, or at least greatly increased, in the decreased genetic material available.

Straight away, I urge you to get both dogs neutered. Do not breed from these dogs. Please.

I am not saying that you should never breed. Please, learn about the gentics, the pedigrees, the particular problems associated with Pekes - and there are many (would you really want to put your bitch through this process without knowing all you can know?) - and what you will do if your pups or bitch are at risk during whelping, what you will do if a pup is badly deformed at birth etc.

Before you even think of breeding, please, seperate these dogs until they are neutered.

The training/behavior problems are really secondary to the intention to breed these animals.
