Most likely. Absolutely.
Most dog owners agree that one bed is not enough, especially if you have multiple dogs. At the very least, it's a good idea to keep one in the crate, and one outside of the crate to establish a sense of stability, but it goes even further than that.
Your dog should have a bed available in each location where they will spend longer periods of time. For example, if your family is prone to watch a few hours of television each night, then they should have a spot for themselves there. If you frequently visit your sister’s and bring the dog, they should have a “to go” bed. If you often bring your dog with you in the car, they should have their own “seat” which will keep them confined, and make them feel secure.
Don’t get too carried away, though. Only have dog beds in the important places where you know your pup will lay down, or where they need the structure to stay contained without being put in a crate. If you have dog beds in every room of the house, you might regret your decision as your dog might start to think they have free reign. But hey, if that’s your goal, go crazy.
