Mysti, who had a litter of puppies as a stray, looses every last marble in her head the minute she sees one. Screaming, moaning, howling, rearing up, just going NUTS the minute she sees one. No barking/growling or aggressive posture, just pure desperation to get to said puppy. Once she is allowed near it, she promptly begins to groom/lick and "chatter" to it.
