The best over all type Vaseline was the Carbolated formula. Vaseline no longer makes it. May can be bought in another brand name. Amazon.com advertises one on it's site.
I often wondered how well those dog boots worked that was used on the sled dogs. Later on I saw foot boots being advertised for use on the Fox and Coon hound dogs. Never found out how the booties panned out over all. Cheers
