actually there are some chew toys you can make without buying anything.
1. Just take a long sock (a new one would be better because it wouldn't have your sent on it) and a tennis ball.
put your tennis ball inside the sock and tie up the sock. My dog really loves it! :) you can also cut a hole in the tennis ball and add one of those tiny bells that ring like crazy when you shake them and sow the whole up and tHeN put it in the sock.
2: take and old garden hose you don't need and a stick that fits perfectly in it. Cut about 1 foot of the hose and stick the stick in it and close it up (it makes a good frisbe)
3:Take some rope and large knot in the middle, then tie another one over it and another and another until there are only a couple lose strands hanging out from the side. then you have to choices.
A Soak the ball of rope in water and then freeze it. my dog loves to play with that :)
B You can also throw it in the washing machine with your clothes (it won't harm your clothes) after you wash it, let it completely dry. then give it to your dog (this makes the loose strands softer and thinner, and more attractive to your dog. :)
4. You can take a plastic container, an old yogurt box would work fine. Poke holes in it, and fill it with treats that can fall out the holes but not very easily. Or you could cover the inside with peanut butter and stick some treats on it. both ways work. my dog loves to try getting the treats out.
5. you can cut 2 holes in a tennis ball and stick a rope through the middle. You can play tug of war with your dog with this toy :)
