I bought this for my senior dog - a 9 y.o. 10 lb. female Pekingese - who doesn't play so often. Her name is Twinkie, and I call her my "old lady baby". But IF she is going to play with toys, they MUST have the crinkle or crunchy sound to them! I am lucky that she has never destroyed a dog (or cat) toy in her life, so I can't say how durable this is. She may have broken or worn out one squeaker in the 7 years I've had her? But never shredded or bit through or defluffed a thing. :)What I love about my dog, is she KNOWS if a package arrives or we come home with shopping bags and something is for her. When we order from Amazon or Chewy, she jumps on the box and wags her tail with her ears perked, waiting to see what she got! Well, with the Pizza Mutt toy, she INSTANTLY grabbed the "box", took out all the pizza slices one by one, squeaked them, shook them, and then brought them over to my slippers (where she likes to hoard her toys). When she was done with the pizzas, she grabbed the "box" and shook it and threw it around!!! She has a lot of "hide and seek" toys, and I've never seen her play with the empty hiding container before!!! Maybe because this one is made out of corduroy, she liked the texture? But it doesn't make noise at all, so it was weird... in a good way. :) Out of her many, many toys (a standard storage tote full), this is her favorite. She gets angry when my adult child's much younger dog - Maple, the 1 year old, 8 lb. Pomsky (think tiny Husky) - grabs a slice of HER pizza!Now Maple, who LOVES all toys, seems to have a preference for Twinkie's toys. All of Twinkie's toys are plush with squeakers and crinkle. Maple has all sorts of toys, and despite her miniscule size, is what I would call a 'super chewer', as she destroys things very quickly! So we try our best to not let her have Twinkie's toys unless being supervised the entire time, and we still have to take them away eventually. Maple has ruined all of her plush toys. Dog toys are expensive, or at least high quality ones are, and I cannot afford to replace things as another dog ruins them. When Twinkie got the Pizza Mutt toy, Maple got a hide and seek toy of her own - a log with black bears inside. Exact same time. Maple ruined one bear within 10 minutes. The next day, a second bear. The third bear was given to Twinkie, who wasn't interested, because it didn't crinkle. As for the log, no dog ever played with it. So far, when Maple has stolen Twinkie's beloved pizzas 🍕, she has not harmed them in any way! Yay! So that is a win. Not even a pinhole. So maybe they are tougher than others, but I still wouldn't leave her with it unsupervised.In a perfect world, there would be 'refill' packs, and I would have ordered at least one at the same time as the whole toy. Then if one got shredded, we'd toss it and have a backup, and wouldn't feel so bad playing "keep away" (or take away) with Maple. Twinkie seems to lose toys easily, so finding the favorite is impossible sometimes! She once had a UFO hide & seek toy with aliens that she would just haul around and sleep with (we called them her "babies"), and we haven't seen a single baby in over a year, but the UFO is laying in the middle of the floor! So, extras would be wonderful!I hope this company keeps making toys like this, and that they make refills packs, because for my old lady baby, it's more about the crinkle than the squeak. The pizza slices are the perfect size for our little dogs, and I think they would be great for dogs up to 20 lbs or so.*NOTE: Each pizza slice has a different facial expression, so they're very unique. Bonus!!! :)Uploaded photos of our furbabies, but don't have any of them with the toys. Oh, well, good for size reference! X)
