We looked high and low to find some toys for our 7 month old Golden Retriever puppy that wouldn't end up in pieces within minutes. Believe me, she is quite the chewer and went through every Kong toy or other "indestructible" toys from the popular pet stores. When we found the Zogoflex toy, we were so impressed that she was able to chew it vigorously for hours and did not break through it. We love that these toys come with a guarantee and that they bounce and float too. She owns every single Zogoflex toy including the Hurly, Huck, Tux and Bumi. She chews them daily and hasn't torn any of them. She's had them for months and we are so incredibly impressed by these products. we wasted so much money on other products. Trust us...these are worth every penny!!!
