Harnesses give you more direct control over your dog, which is especially important when training it. For dogs that fight any kind of restraint, a harness is key because it’s much harder to slip off than a collar is, so the dog won’t be able to wriggle out of it and run away or injure itself. 

There are plenty of benefits to having dog beds. They can be used for napping during the day and sleeping in at night. Unlike the floor, a bed will keep your dog warm, support arthritic joints, and prevent calluses. It's a place of security that belongs only to that one dog, and they should always feel safe in it.
