As an active dog sitter, here is a product I wouldn’t want to be without: The Chuckit Dog Ball Launcher. If you have a dog who can’t get enough of fetch, this tool is a must and will save your arm—trust me! There is a variety of Chuckit brand balls on the market, but tennis balls (which are far less expensive) fit the medium size launcher as well. Consider buying the 14” launcher for smaller breeds—both available on Amazon.
