Hello! We have a 4 year old lab mix we adopted 2 years ago. He becomes destructive around our house when he's left alone for too long. We do mental stimulation, playing fetch, filled bones per our dog trainers recommendation, and even Trazodone prescribed by our vet. We purchased a Ruffland crate (he has escaped all of the other crates we've tried to use) and we are currently in the process of crate training him. He sleeps in there at night with no problem. He has been eating his meals in the crate with no issues. Our dog trainer recommended placing a kong or filled bone in his crate so he associates it with positive things. The issue is, I don't think he's that persuaded by those things in his crate. When we've placed these items in the crate with him while we're home- he ignores them and won't touch them. I'm wondering if anybody has any advice on what else we could place in there to let him know it's a comfortable place that can be enjoyable.
