This little puppy is super social and outgoing. he is approx 5-6 months now and weighs approx 20 ish lbs so we are thinking medium size at adulthood 40 ish lbs. The vet thinks he is border collie from his size, bone structure, coat, ear set, body type, muzzle length and he named several others but you get it, right. he cannot meet another dog without kissing it endlessly so if you have another dog they will need to be prepared for lots of kissing. he is so sweet with people and dogs, just super easy going and loving. Great little puppy.
