First, from the website centhound, http://centhound.com/sock-toy Their photo shows a dog making his own toy putting an empty water bottle into an athletic sock. Someone else will have to tie a knot in the sock! That's all it takes, along with supervision during playtime, especially for the 'heavy biters' among our dog friends....you know who you are!
Next, for dogs that like to chew, and especially for teething puppies, a frozen toy! Tie a knot in a washcloth or hand towel that has been soaked in water and squeezed mostly dry. Place the damp knotted cloth in the freezer for several hours. Give to your pup or dog and watch them enjoy it. (Really watch them....you DON'T want them to eat the towel!)
Finally, a toy for dogs that like to tear up cardboard--I call this one a "Doggie Fortune Cookie." Take a paper towel roll--just the cardboard tube in the center--and smash one end of the tube flat. Fold and roll the end until the tube is closed, then bend the end of the tube to seal it shut. Place a dog treat or two inside the tube and repeat the closing technique on the other end of the tube. Shake the 'Fortune Cookie' before giving it to your dog, and let him open it to get the treat. If you use two different diameter tubes this toy will last longer.
ENJOY, and share your favorite frugal dog toy, please!
