Roxie, our dog, is a Grey County mutt. Both her parents were mutts too, so I take that to mean she's a genuine mutt - but she seems to have come out of it all quite well!
She has the markings of an Australian Shepherd, with white nose and tail tips, white paws, and a white collar, but neither parent had any white at all. So who knows!?
At the moment, I'm not allowed to walk her on a leash, as we usually do (in case she pulled suddenly), so I'm just walking her off the leash, around our trails in the meadow. We live on 2 1/2 acres, but I refuse to mow anything more than a circle around the house; however, I do mow trails out back, which she seems to love. This is a week ago; it looks more white now!
This freedom seems to appeal to her. First, she has to roll in the snow several times. A lot easier than if she were on a leash.
She seems to tire of that after a bit and take a 1/2 second lying still to recover, then up and at it. Off the leash, she can stop and sniff as much as she likes, and then she has to romp to catch up to me. She doesn't get as long a walk usually, but it's a more natural dog-walk, a mixture of sniffing and running rather than just walking with me.
So is that good or bad? I'm thinking it's mostly good, and I may keep it up even after I've recovered. Perhaps fewer long on-the-leash walks, and more freedom on the meadow trails?
Of course Roxie's not the only critter on the trails. A small herd of deer seem to wander through regularly, overnight or very early in the morning, so we hardly ever see them. Of course they explore the garden among other things, hoping for tasty morsels!
