Hi, I have a St. Bernard/Great Pyrenees mix that is about 11 months old. He started chewing up the bathroom wall and cabinets as well as other household things when we're gone. He has toys and has our other dog to play with as well, but still chews. Any advice is welcome!

Oh no! If he will tolerate a crate, I would strongly consider this to help prevent him from swallowing something he shouldn’t and to prevent more damage to your house. I would also consider some calming chews like vetriscience composure and a calming collar like adaptil. If this doesn’t help, I would talk to your vet about starting him on an anti-anxiety Medicine. I hope this helps!

    It sounds like he may be having some separation anxiety. You could try a calming collar like sentry. You can also try some calming essential oils. DoTerra oils have oils that are safe for pets. Finally, if you aren't having any improvement, I would talk to your vet about starting him on an anti-anxiety medicine like fluoxetine. You can also talk to a trainer for ways to help improve the anxiety and prevent him from having to be on medicine long term. I hope this helps!
