Hehehe 😂 they are so funny....they are like inquisitive children. Mine too love squeaky toys, but like yours soon kill it by removing the squeak.
Over here we have Mr Price shops, they sell all of their items much cheaper than elsewhere. I found a brilliant ball in the pet section with a squeaker inside, that when your dog retrieves the ball, it makes a strange squeak noise as it runs. It's the only squeaky that has lasted so long.....3 weeks and counting! I'm in bed now, but will post a pic tomorrow of the ball.
