My wee Corky (Yorkie X) has her daddy's Yorkie coat...cottony

and when I put her in her harness...or any of her cute little outfits, she gets mats under her front legs (which I affectionately call her arms...much to my hubby's chagrin)...does anyone know of a harness that won't cause that? I usually just comb her out every time she wears anything ... is that just the norm for everyone?
