So my lil pup (mini schnauzer) has been licking his rear for the past few days, in the same spot (just on one side), A LOT these past few days, especially in the evening when I get home from work. His stools have been regular, he is acting normal, he doesn't appear to be sick in any way.....he just licks and licks and licks and it's kind of turning red by the time he stops. We're planning on taking him to the vet soon for a check up anyways, but anyone know why he may have started to do this all of a sudden? can it be worms of any sort? or bug bite? hmmm ... it's been a week almost and we can't get him into our vet until tuesday
