For teething puppies mix chicken or beef broth (look for low fat, low sodium brands) with 1 ½ cup of water. Pour them into ice cube trays to made broth ice cubes. They are tasty treats on hot days. (be careful when doing this with very small dogs, as they may get a chill. I have heard of small dogs getting too cold too quickly when chewing on ice.)
Do not leave your pet in an area with dangling phone cords, drape cords or other items that they may strangle on. Be aware of electric cords that may be chewed by the pet.
