Canadian horses are well known to be black, chestnut, brown or believe it or not, grey. Time has change as lately a few Canadian horses have been registered has been ash white or cream white or palomino. Nathalie Levesque had publish a very good article to demystify the genetic and color in horses to conclude that even if a horse is white to the eye it might be palomino. We just bought Theta, an ash white Canadian and we are going to have her tested for the cream dilution gene. I was told that if I breed her to a bay stallion, we might end up with an Isabelle horse. If Theta is sired by a cream diluted stallion, then we might have a cremello Canadian. The question is how many color is there in the Canadian horse breed and should we have Theta sired by one of the stallion bay or palomino to introduce a new color in the breed? The attached pictures does represent different colors and shade...chestnut with flaxen mane, bay with cream nose, black, burn chestnut and white. Any opinion on introducing new colors?
