So Riley is our 6 year old male (well 6 coming january 2011) and he's basically a jerk. He refuses to play with any other dogs unless its Zena and he gets pissy about everything. Well Shelby came in and he was perfectly fine. Shasta came in and he's a complete jerk. Shasta has been with us since she was 12 weeks old. She's now 5 months old so we've had her for two months now. Until tonight, Riley has been... well less than steller. Shasta doesnt even have to be in the room for him to be growling at her. He's a jerk. We know this. he's always been a jerk. He doesnt appreciate "young" in anything. He's very tolerant but would rather just ignore and be ignored by puppies. Shasta has been trying so so so so hard to be friends and Riley just growls and snaps and in turn gets yelled at by us for his rotten brat behavior. He knows better. Shasta isn't an overly pushy puppy and therefore his behavior is him just being the spoiled brat he wishes he was. Below is the video i got of them actually beginning to play. Before i could hit record, Riley actually play bowed at Shasta when she did it first.
