Specialty dog beds are made for all kinds of dogs and they can solve a wide range of various problems.
Things to consider: Dogs who need heat, sleeping off of the floor, and flea & tick control.
Need Heat - Specialty heated dog beds are superb for small dogs, shorthaired dogs, and senior dogs who tend to be more susceptible to cold.
New Heights - If you cannot stand watching your dog sleeping so close to the cold, hard floor, consider getting him specialty dog beds that are raised off the ground. Make sure he is young and spry enough to get on and off the raised dog beds comfortably or one of two things could happen -- he will stop using it, or he will hurt himself. If it is too late, and you have an expensive raised dog bed that your dog just can't seem to comfortably get into and/or out of, buy some pet stairs or a ramp for him to better climb up and down with.
Smelly Solution - Cedar dog beds are a doubly beneficial treat in that they help reduce pet odors and they are a natural repellant to fleas. If your dog has a dog flea and tick problem or a problem with B.O. (body odor), make cedar dogs beds their specialty.
