We have two 35lb Mini Aussies and a 75lb GSD. One Aussie is a squeaker remover and the other is a stuffing puller. Our GSD is relatively gentle with toys but has one helluva strong "chew." This brand of toys holds up well and the dogs seem to prefer them. I like that the squeakers are difficult to remove, they don't have "hair", and they have limited stuffing, making them safer for the dogs.
