My Dog Eats All His Toys. So why does your dog rip up and destroy his dog toys. The following are a few possibilities.

The esophagus of a dog is larger than the outlet of his stomach. It doesnt have to be anything specific that sets the dog to tear the toy to shreds besides simple boredom. If your dog is a puppy and likely to be teething try freezing some of his toys.
Your dog has learned not to rip up furniture rugs and shoes but every so often when hes had too much time on his own he needs to vent his pent-up energy on something.
Likewise some puppies and dogs like to raid the garbage and chew up discarded sanitary napkins and tampons. While most of the time when it is a puppy chewing on things there is no need for alarm if you have an older dog who has started to chew on inappropriate items you need to call the vet. If the dog is growling snapping or lunging when people or other pets get near his hoarded toys then lure the dog away with a treat put him in a crate or fenced area and then put the toys. This problem is most easily resolved by always putting dirty underwear in a closed hamper.
