I get his on Amazon! Sometimes I find them at TJ Max or Marshall’s...ZippyPaws - Woodland Friends Burrow, Interactive Squeaky Hide and Seek Plush Dog Toy - Hedgehog Miniz, 3 Pack [link]
The only plush toy my dog has not destroyed is this flea although I must say I don't know why. He usually likes to rip an arm or leg off a toy then pull the squeaker and stuffing out through the hole he creates.
As far as squeakiness without stuffing that last, he likes JW Pet Company Ruffians Octopus Dog Toy and the Kong Airsqueak tennis balls.
When I first got my 4 year old husky mix she showed very little interest in toys. How long have you had yours? Maybe it is still coming out of it's shell.
After a while it turned out the toy that really turned my husky on was duck.
