ok, maybe this a wierd question, and it's (hopefully) months early, but i'm a little bit worried about winter. Heidi and I take A LOT of walks, and winter in Iowa lasts about half the year, during which they put salt and what have you all over the place. I know it's bad for their paws, but i'm not sure how bad or what to do about it. I have heard of doggie booties, are those a good idea? or should you just try to wash their paws off really well when they come back in? i realize this sounds like a pointless question given that most of the country is either flooded or in a drought right now, but where darling poochie's exercise is concerned I like to have all my bases covered! any advice would be appreciated. thanks!
