Snowmelt Garbage Dog Treats

Now that the snow is almost gone in Minnesota, I'm finding a lot of things as I walk my dog. The sidewalk salt is bad for their feet, but I can't give the dog a warm paw wash every time we come inside. There's a whole winter's worth of garbage, lost items, rabbit droppings, decomposing squirrels, cigarettes and poop which has all melted out of the snow pile, and is now littering the muddy, moldy grass.  I even found this 1/2 onion on the boulevard, which fell into the snow sometime during the winter.  Onions are toxic to dogs. My dog will grab anything in his mouth, so I have to watch the ground carefully. It's ugly out there.
