Red handled millers forge on all dogs of all sizes of all breeds or all nail colors. I have bought over 10+ pairs ranging from small to large clippers. None work like the millers forge that I use. I tried to use the other ones and they don't feel the same, don't cut the same and does apply a significant amount of pressure causing the dog to freak and flinch.
I have small hands and these are perfect for me and I ended up throwing all the other ones away - orange millers forge included ( I had two the med and the large ones). These are very nice because they slice through the nail.
