  About the Gold or  ' ee red masking gene '

The gold border collie is a beautiful sight to behold. Some gold border collies are the color of butterscotch candy or ginger, while others can be very light almost a cream color. An interesting fact is while always being some shade of dark gold to light cream, the gold color is correctly called in genetic lingo, ' ee red ', the masking gene. It masks all colors and patterns so it can be very difficult to know the true color or pattern of the individual dog.

Gold border collies can be any color, even though you can't tell except by the color of the nose or eye rims or by doing color DNA. Golds can actually be a black, brown ( aka red, which is incorrect ), solid blue or lilac. You can only tell by their nose or eye rims when they are under a year of age or younger for best results. The gold border collie will have color fade of their nose, not to be confused with a non pigmented nose of bright pink. This is normal and happens with age. The nose seems to just lose the dark color it was born with, as a result it makes it difficult to tell the actual color of the dog.

The gold border collie can be any pattern which includes merle, sable, saddle, brindle or tan point. It is very important in breeding the gold border collie that one is aware of the presence of the merle gene. You should never breed merle dogs together as this could result in ' homozygous merle ' or ' double merle ', puppies with abnormally small eyes, or born without eye balls at all! Pups out of two merle's can be deaf in one or both ears as well. Since there currently is no DNA test for the merle, its best not to take the chance and only breed to a known solid colored dog out of lineage without merle in it. If in doubt, always breed to a solid mate until you're certain about the presence or lack of merle.
