Louisa & Harley - welcome to COL.
I have a coat king that i don't use that often, so if you want to borrow it when her coat is a bit longer for a few weeks just to try it out i can bring it to agility one week.
Taz is neutered and i was told that keeping his coat long would be impossible, but with work he is starting to look really good - although his legs are a bit thicker than his back.
