Really important advice... THE GOLDEN RULE...
You can teach a dog to treat his or her toys with greater respect. How you ask?
If your dog begins to treat the toy with damaging results, remove the toy immediately and place in a visible but inaccessible (to the dog) location for at least 24 hours. After that time has passed and preferably at a similar time of day (dogs love routine) return the toy to circulation, but this time keep a closer watch and, if your four legged friend begins to repeat the destructive behaviour, again remove the toy and place in the same visible but inaccessible location.
Repeat this process for at least seven days. If the behaviour does not improve during this time, I'm not certain what else to suggest, except maybe longer periods between the return of the toy to circulation.
Here is a photo of my fella's favourite and most robust toys...

If and when the link fails... In order of "robustness" and favour...
The green squeaky toys Ee-Ee (left in photo) and Aw-Aw (right in photo) are the oldest and by far the most robust. Ee-Ee the "squid" (it's a guess, we've never truly figured it out) is over ten years old and surprisingly maintained its squeak, after which it was named, until last year. I'm not certain about Ee-Ee but know for certain that Aw-Aw is manufactured by JW Pet Company Inc, based in Teterboro, NJ, USA. Aw-Aw is dated 2007. They are of very similar thick rubber-like material and have been treated brutally and extensively both inside and outside, Ee-Ee more so than Aw-Aw.
Red-Rope has been a long time favourite and despite suffering some significant unravelling has been and still is a favourite chewing toy and popular wrestling toy.
Yellow-Duckie taught us the golden rule detailed above. Yellow-Duckie was one of three, however one sibling was left behind at a holiday destination and the other lost a wing. Yellow-Duckie still squeaks although occasionally the squeaker needs to be reinserted. Yellow-Duckie was purchased in 2005 and is the currently preferred throw and catch toy.
Ruffous (the dog) is a recent purchase (two years ago) that was expected to last a week or two. Application of the golden rule detailed above has significantly prolonged Ruffous' life. Despite loss of coat, tail and minor limbs, Ruffous still squeaks and is popular but treated with a little more care by Bill the Brown Dog.
