a Blue Merle is a Border Collie that is a whiteish/gray color whit little black spots
Blue merle border collies are pretty common. It is a dominant gene. However, sometimes breeding two blue merles together can cause health complications.
Blue Merle. It's beautiful on Catahoula Leopard Dogs. :D

No (although rough collies don't come in "red merle;" they come in sable merle, though it can be difficult to tell an adult is a merle). In general, however, if you mate two merles, the litter will wind up including an average of 25% homozygous merles, which will usually be excessively white and have a high probability of being deaf and blind.

First of all you need to have an american pitbull terrier that carries the merle gene, and there is no way of knowing if a pitbull carries the gene unless the merle pattern is displayed on it's coat or you have the blood line record, the reason is because the merle gene is receive. If you don't have the blood line record then you absolutely need one of the parents to be merle and it doesn't matter if it's a red, chocolate, or blue merle and the other parent needs to be blue and you will produce blue merles. Of course if you have a blue merle and a blue you will produce more blue merles but if you have a red or chocolate merle and a blue you will not produce as many blue merles. Typically a breeding pair that has one of the parents being merle will produce an average of about three merles per litter, that is what my females have produced out of breeding with my red merle male three to four merles per litter. Remember you can not breed two merles together because you will produce dogs with defects.
There are six standard "show" colors in the U.S.; Fawn, brindle, black, blue, mantle, and harlequin.If you include non standard colors there are at least 29 total color/marking combinations I can recall; piebald/plattenhund, merle, blue merle, red merle, blue mantle, fawn mantle, brindle mantle, fawn harlequin, brindle harlequin,blue harlequin (or porcelain), merle harlequin, blue merle harlequin, red merle harlequin, chocolate, chocolate mantle, chocolate merle, chocolate harlequin, blue masked fawn, chocolate masked fawn, merle masked fawn, blue brindle, blue brindle harlequin, and white.I'm not sure on different colors of piebalds, haven't seen one, but I imagine each color category is possible.
