I"m having the same problem with my golden, except I think it may be a combo of ice and salt. I try to wash his paws everytime we come in, but that isn't always possible. His one back paw is a little red and sore so i've been putting a cream on it after I wipe them off. This seems to be helping some (can't remember the name right now). I was thinking of trying the doggy booties, but everyone laughed at me! lol I may try them anyways because he loves to run in the snow but has to stop when his paws start hurting.
