Breed that healer with a border collie or a mountain cur, love my border collie/healer cross.
Yep, the little mutt in my avatar is a mostly heeler/sheepdog mutt. When my aunt passed years ago her wishes were for her ashes to be scattered along with those of her beloved newfie/lab mix Bear. I'm thinking I'll request the same w/respect to the ashes of that little mutt.
My bigger heeler is actually a heeler/stumpy-tailed cattle dog mix, that latter breed being poorly known outside Australia, but since they are basically taller, leggier heelers born w/out tails I dunno that counts as a mix.
And I've posted this pic before of my sister's heeler/aussie mix, bred on purpose by my other sister. A great dog...
