You have all been very helpful. We do walk in the woods & fields here on the farm. Sometimes the snow is light & fluffy & other times it has an icy layer on it. The icy layer is what bothers old Bob. A waterproof boot would be the way to go if possible with some tread on it. One of you posted s site with a pattern to make your own. I have to do some thinking but I bet I could come up with something that would work. I wish we did live in an area where there were mushers & dog trails, here we make our own trails through the woods & fields. I may try clipping the hair that sticks out & gets ice stuck in Bob's paws too. Although that hair has to be there for a reason? I clip the hair along the back of his legs because they just get full of ice balls. He sure acts like a young pup when we go for our walkies. It is good to see him bouncing around & feeling good. I just love my old fellow.
