This to me really is the only option. All of my dogs back in PA have always been crated their whole lives when we're not home. When Honey moved from PA to NC with me, I decided she won't be crated anymore. She scratches her eyes off of crates causing her eyebrows to bleed, hair gone, scabs, no whiskers kind of scratching off. Unfortunately, my parents didn't trust her enough to let her out of her crate when they were at work (8+ hours). They also thought she was the one peeing in the house everywhere.Put them in crates or in an ex-pen when you leave.
Since I brought Honey to NC she only touches a crate when maintenance people will need in my apartment. Her eyebrows have healed, still missing fur, but her whiskers came back. She has never once peed or chewed up anything. She actually just sleeps on the couch all day
.That being said, Ruutu will be one of those dogs that gets to live in a crate until he's much much older. He chews our baseboards all the time and that's with us watching him. They're actually pretty covered in hot sauce and I honestly think this dog loves hot sauce. We leave them out by themselves for maybe 5-20 minutes if we go over to my neighbor's apartment, but that's the longest I'll leave him out.
