My 4 year old lab male has raised our 18 month old chessie. They have been best friends and yes they do tussle and take turns trying "dominance" on each other, but always friendly. The chessie went on a dove hunt today, his first, and all he was asked to do was be steady and calm, my husband did not shoot. After the day was over, the chessie, who has always been friendly and outgoing with other dogs, went after his training pard, another chessie. When they got home my lab was ecstatic to see him. Scout went after Indy!!!!! We took them on a walk around the neighborhood, and Scout was amazingly attentive to Ralph, heeling perfectly, etc. But every time we let them "go play" he attacked Indy. What the heck is going on here? Did Scout decide he was the BMOC because of the field work???? Indy is distraught, his best buddy is being mean. What would you make of this?
