Already asked this in a few places, but I was wondering if anyone has any advice for me on my German shepherd collie cross, he has a bad case of separation anxiety. I've tried crate training, he just makes a mess of the cage and tries to knock it on its side to get out, kongs, which he chews through and desensitisation. Any other advice or if not does anyone know of any decent dog trainers for this issue? Thanks. :)
