dogs in crates
Anyone who thinks it's okay to keep dogs in crates, EVER, has got shit for brains. Please don't get a dog, get a stuffed animal. The only time dogs belong in cages is when you're taking them to the vet. A dog is part of the family, not something you stuff in a crate so it doesn't get your furniture dirty.
This stuffing dogs in crates for hours is relatively new, no doubt started by people who sell crates. Dogs do not belong in cages, or chained up in the backyard. If a dog isn't part of your family, I repeat, get a stuffed fluffy plush animal. You don't deserve a dog.
