I went to the pet store today to get some Musher's secret. The pet store didn't have it. I know I can order it online, but I also remember someone mentioning vaseline. Musher's secret is expensive and if vaseline works well, I'd rather use that. Is it safe for dogs to ingest a small amount of vaseline? Maya does lick her paws. Also, does the vaseline keep the snow and ice from balling up in the pads?
