West Paw Designs (Bozeman, Montana) makes the most durable toys. They are guaranteed destruction-proof; will replace (or refund?) if your dog can chew them up. Made in USA, lots of different types and sizes, and NO hazardous materials. My mighty-chewing lab loves them. Their website is: https://www.westpawdesign.com/dogs/dog-toys (https://www.westpawdesign.com/dogs/do...). You can also get them at Amazon, Chewy, and a few other sites.
