For those chicken-chasing dog owners, i need some help! We got a new dog saturday (tucker,in my avatar), and before we got him we did a meet n' greet with my chickens, to make sure it didn't turn into a meet 'n eat. He got along fine with them and barely glanced there way. But yesterday he had his heart set on chasing them. what would he look like if he meant to eat them? His ears are up, and he is panting. would he look different. He has gotten along with goats,rabbits,guinea pigs, cats, and other dogs in his past. ETA- he IS on a chain because we need to establish some boundries before he is loose, do you think he just has access energy and needs something to chase?
