Repairing dog toys-- great. Toys destroyed in a minute or two and I inserted a new squeaker and pet was happy again.I use these to make my own chewy toys for my puppy. There great, he LOVES them, and there so much cheaper.Dog loves themMine are crazy about squeeky toys. They can find the squeeker and chew a hole to get it out in seconds. Then they gut the stuffing out! They think this is fun fun fun. I refill it. Sew it up minus the squeeker. They still play with the toy, but not like they do when it squeeks. But now, problem solved!!I am always doing surgery on my dogs toys. Replacing squeakers all the time. These don't last too long, but the dogs love the noise!Great value for the price. I use them to train my dog! It’s amazing how it diverts her attention.I buy these to satisfy my dog's desire for the squeaker out of toys, but without all of the fuzz to pick up. My dog would rip a toy in about 1 min to get to the squeaker and play with the squeaker for quite a while. I decided to buy the squeakers and get rid of fuzzy toys! I throw it in the house for fetch and it works very well.Great value for the price. The inner part that makes the sound is a little loose on some of them, so I would be wary if you are using them in dog toys. I am actually using these inside of crocheted frogs (for people, not dogs), so that isn't an issue for me. I definitely would not give one to a dog to play with by itself! It also doesn't squeak super well when it is inside a toy along with stuffing, I think because the plastic is a little thicker.After ordering from another on line site and receiving rubbish squeakers I was sceptical but these are great and such good valueMillie our little Jack Russell is a squeaker expert so we need them to be chewfastic lasting and strong and these fit the bill Her toys are permanently in A&E due to her knack of squeak locating and also going for the jugular but she sits patiently waiting for squeak replacement emergency surgery and these seem to be top squeaks.I ordered these squeakers to give to my dog as she has literally eaten through at least 100 toys over this last year in the hope of receiving the annoying plastic squeaker so Although probably not the best use for these squeakers they have made me and my dog very happy. ?I bought these for dog training as the normal clickers did not get my dogs attention! They are the right size and are suitably loud enough!!Excellent thank you. Four of my dog loving friends are sharing with the squeakers and we are repairing doggie toys where the squeakers have been popped by sharp teeth. Some new toys only last about 10 minutes and the squeaker is popped, so these replacements are invaluable.I use these to put in toys I crochet. So not just for dogs.
