When purchasing a dog house, your will need to consider your dog’s breed.  Think about the thickness of his coat, then consider the climate in which you live and find a selection of dog houses that will adequately protect him from the elements.  Next, think about your dog’s size. He’ll need enough space to move around, sit and stand but not so much space that he isn’t cozy and warm.  Remember, if the dog is still a puppy, you’ll want the house to work for him even after he’s full grown and you can always add extra blankets in the meantime.  Finally, make sure the house you choose is well constructed and has plenty of ventilation.  Add some chew toys and your dog will have a happy home.
