I recommend using the KONG Extreme Dog Toy
Style: Sport, Size: Large
Helpful for throwing as much as my dog wants to fetch. I actually had to get a cortisone injection in my shoulder a few months after getting my dog - never had a dog with this much energy before! The Chuckit really helps. Downside: The ball that comes with it is larger than a tennis ball, so may be too much for smaller doge. I can't imagine my sister-in-law's french bulldog carrying it! Also, in our house it gets destroyed within minutes, as my dog is a strong chewer. For this situation, I recommend using the KONG Extreme Dog Toy, Black, size Large. This is shaped sort of like a snowman, which means it bounces unpredictably at times. My dog eventually chews the "head" off of this toy, but the remaining 2/3 still fits in the Chuckit (and is actually easier to throw with the "head" missing!). One caveat: the KONG is significantly heavier than the ball included with the Chuckit, so be aware of that... Also, we ordered our first Chickit in October 2015, then needed to replace it in May of 2017, as it broke. I think the plastic became brittle over that time, as we left it out in the sun & rain in Florida. Since it is cheap to replace, that's not a big deal. (We ordered three Kong toys over that same period of time!) To summarize, it's a very helpful tool to get the ball further, faster, with less strain, than without it. Knowing there are alternatives to the included ball for heavy chewers makes it worthwhile.

Great Ball Launcher!
Style: Sport, Size: Large
Our dogs love this ball launcher! I can throw the ball long distances without any arm strain. The balls wear out, and as described by others, tennis balls don’t fit. Buy extra balls if this is of concern. We bought a few of the “Chuck It” rubber 3” balls and they have worked well for our dogs. It’s a great value and fun for the dogs.

Chuckit!! Just Chuck it!!
Style: Sport, Size: Large
Chuck it further than your skinny little arms can chuck it. Doggo loved this, I loved this and when we were done Doggo promptly hid it under the porch so I couldn’t take it from him. It’s not a squeaky toy, it’s for fetch. You wing it out toward the yard and it flies, bounces if it’s lucky then is attacked in an adoring manner. We like it!!
