especially in the summer and its driving me mad, i was told he was lacking in salt, how can i add salt safley to his diet? he's a welsh / scotch sheepdog.
Dogs dont need additional salt in their diet, licking is natural behavior for dogs, and starts when they are puppies, when they groom one another. In the wild, puppies will also lick their mothers mouth to stimulate her to regurgitate food.
In adulthood, it can be a sign of dominance or submission and also a sign of affection.
