A real favourite for dogs is a throat. You can buy then dried, raw, or even wrapped in lung.
Mainly they are from a cow and as such sizeable feasts - especially for small dogs. I've heard of bully tubes being buried, saved for a later date, others left to go mouldy and then dragged out to be eaten in front of company.
Enter the goat throat. Smaller and more compact, this is a bully tube in small dog size.
Pro tip: I've heard that these can also be stuffed with pate, frozen and then eaten as some long lasting grisly ice pop during hot summer days. Hmm, gross. Your dog will love it.
