We recently got a 9 month old, started GWP from the breeder/trainer. We have a 9 year old Lab who has never been a hunting dog. It took the dogs a few days to get used to each other, now it seems like all they do when together is fairly rough playing/fighting. It usually ends when the Lab gets mad and gets after the GWP and one of us breaks it up. The major problem is, the fighting is relentless and it is driving my wife crazy. Any suggestions on how to stop it? We separate the dogs when we are away. But usually they are ok together in the kennel when we are not present. most of the playing is when we are present. Any ideas? Thanks!
