Hit the butcher for a great chew toy for your dog
Go to a local butcher and ask for a femur bone from a cow or steer.
They last a very long time and your dog will love it.
This is a great tip. Natural bones, especially the really big ones, are pretty much indestructible.
Some tips for these bones though is to remove as much of the meat as you can, dogs who aren't used to raw food will get an upset tummy otherwise!
Also, they're not good as outside toys as dirt, flies and such can be a hazard, especially in hot weather.
Other than that, good reminder that not every toy comes from the petstore :)
