Using this dog toy is easy. Just give it to your dog, and they'll start enjoying the chewing fun right away. It's great for training - you can use it as a reward when your dog behaves well. When it comes to size, remember this is a large/giant toy meant for dogs up to 50 pounds. If your dog is much smaller or larger, it might not be the best fit. For maintenance, you can wash the toy with mild soap and water from time to time to keep it clean. Keep an eye on the toy during use. If it starts to show signs of excessive wear or breakage, take it away to prevent your dog from swallowing any small parts. Enjoy watching your dog have a blast with this fun and functional toy!
