Most dogs investigate new surroundings with their mouth. With a dog in the house, it is best to keep a home that is free of clutter that a dog can reach. When you are introducing a dog to a new home it is best to familiarize him to your home room by room.  You don’t have to show him the full house in one day. Let the exploring be a privilege that is done with you! As he is learning the rules of your home it is also best to keep him tied to a table or bed (solid piece of heavy furniture) when you can not watch him. Dogs like to be in human company so you could tie him near where the action is but away from foot traffic. You could also block off an inappropriate area for your dog with baby gates. Another way to make a dog comfortable in your home is to designate a safe spot for him where he can escape and feel comfortable. A crate can easily become your dog’s safe haven. When you can not watch him you may keep him in the crate so that he doesn’t get into trouble.  (See below for common household hazards and poisons. )
Garbage cans and hampers are places that dogs like to get into and steal items from. Make sure these are in closets or cupboards out of the dogs' reach. Dogs are also particularly fond of cat food and cat feces/litter.

Outside Your Home
                Just like in the home when your dog is outside you need to be concerned of what your dog is exploring with his mouth. Dogs will not know what is good or bad for them. There are some outdoor plants that are poisonous to dogs. Other yard hazards can be toxic chemicals, foxtails, dangerous debris like nails, broken glass, and barbed wire.
Do not assume that dogs are safe around pools. Dogs have been known to drown when they jump into a pool and can not find the stairs or get stuck under the pool cover.  Also dogs may try to drink the pool water. Chlorine can cause dogs to become very sick and dehydrated. Dogs should be supervised around pools or you may find it necessary to set up a fence around your pool.
