Hi.
As all dog people know, our four legged friends like squeaky toys. The louder the "cry" the better the enjoyment.
Unfortunately that squeaking sound does irritate the proverbial dookie out of most of us in no time, leading to a very sad puppy/dog.
Now the squeaking doesn't bother me at the slightest for some reason, but the same can't be said about my cl wife.
And as a lab can look unbelievably sad when they're happy, just imagine their expression when they're sad because someone yells at 'em and takes their toy away

.
When the wife came home with this new plush blowfish squeaky toy the other day that squeaks with a frequency well above human hearing range, the engineer in me thought that she had been had. One squeeze proved me wrong as our lab came rushing to see what was that heavenly squeak.
Needless to say, the blowfish has been his new favourite toy for an entire week now, with no end in sight.
Now I don't know that much about its long term durability since we seem to have a lab that we were somehow able to rid of the "seek and destroy" behaviour he had as a pup, but the bulb seem to work as fine as it did the day one.
If a week sounds like a short time for any kind of evaluation, You probably haven't experienced the CP dog toy quality vs. an energetic dog.
IMHO/IMLE if it lasts a week, it'll last a year.
The only thing that does bother me a bit is WHY DIDN'T
I THINK OF THAT. It would've been easy to adapt a dog whistle onto any or all of his toys as a pup, and we would've had a lot less irritation in the house.
Regards
Sam
