Large dogs and extra large dogs require more thought and planning when owners purchase a permanent dog bed. Even though large dogs can be just as lovable as their smaller canine counterparts, they require a more complex sleeping situation than small dogs.

All puppies are small dogs - some, however, won't be small for very long. You have to know how big your dog is going to be when it is fully grown before you can buy it a bed of its own, unless, that is, you don't mind buying your beloved canine friend a new bed every six months or so for several years.

Some people are so attached to their pets that they wouldn't dream of asking them to simply curl up on the floor to go to sleep. Pet owners, especially dog owners, have created an industry for dog beds that rivals the bedding industry for humans in both creativity and profit margins.

Like us, birds need variety in life. To be happy and healthy, they need socialization and exercise. This cannot be accomplished if they are cooped up in a cage all day. Birds need time out of the cage to move freely.

As much as you love the sound of your new little bird, you probably don't want to hear it at the crack of dawn. If your feathered friend's morning song is interrupting your sleep, you might want to buy a bird cage cover. Though not an absolute necessity, covers have some definite advantages.
