our dogs lick their paws after bath aswell, they also franaticly lick our legs after we have taken showers/baths, so i think that this is rather something not to worry about. but keep an eye on his paws just in case, as you say. our male has learned to stop licking his paws on command. i want to keep his paws as dry as possible since he easily gets fungus there even though he gets his special food.
