Jrt x patt 14 wk old bitch.Quite bright learning but she eats everything apart from dog poo and quite aggresive when playing with humans.She know what leave it means but she pulls or runs away chewing whatever she has quickly grass, rabbit crap, sticks, slugs, snails, etc.
When i finally get a grip off her she fights with her paws wriggles struggles and clamps her jaws on object.I have to prise her jaw open to get said object one time it was the base of a broken glass bottle other stuff been ripped cans
Any ideas how to cure this or will she grow out of it
