I am 62 years old and have had a life time of pet, dogs. From German Shepherds, dachshunds, pitbulls and a few mutts. I have never had issues with a dog completely chewing something and destroying it (except stuffed toys). I decided this time with a Staffordshire Terrier, that at 10 months chewed the door knob off the door, completely destroyed two KONG toys that a previous Staffordshire Terrier barely chewed to find the ultimate toy for him. I did a little research and found your website that listed a toy called GOUGHNUTS. Well, I am happy to say, the now 1 1/2 year old uses this toy to chew on and has literally only destroyed approximately one-eighth of it. Yes, it is a little pricier than most dog chew toys. One of the first times I got my monies worth. But, I will forever tell anyone that it is the best chew toy, training toy for a tough dog. I normally do not write reviews, but I have never knew anything in the world today, to be so good. Thank you for your website.
