Answer
Hi Lupe

Interbreeding should only be done with the best of the best.

What trait are you looking to hone in on? Are you aware of the lines of the dogs? Do you know of any health issues, however small that have been displayed in their gene pool? When you do a close breeding ALL the flaws that were hidden will come out.

It's important to be experienced and knowledgeable before considering doing a interbreeding.
