Below are links to other sites where you will find important information about Merle Chihuahuas. I will add more links as I find them. As with ALL breeding, education is KEY!
Chihuahuas of a Different Color Forum
Note: I have not been active in this forum for a number of years, and due to the facebook age there really isn't much activity on the forum any longer, but there remains a lot of good information and reading material on this forum for anyone considering a merle Chihuahua, including available/recommended testing, information on "hidden" merles, making educated breeding decisions, etc. I will be going through the forum as I have time and consolidating all the important reading information on the forum into one place and adding it to this website; in the meantime, the information is available on the forum if you dig around a bit for it.
