You got a dog. You wanted one, went to the Humane Society, and picked one up. Nice. But now you realize that you've made a huge mistake—it's way more responsibility than you ever realized. What do you do? You can't take it back; you'd feel way too guilty. (Plus, the 48-hour grace period is over, and you'd lose your $75.) Fear not, there is a solution. It's called iFetch, and it does exactly what it sounds like.
iFetch launches mini-tennis balls all over the yard; when your dog retrieves one and drops it back in the funnel, the process starts all over again. Fetch, drop, repeat. All the while, you can let out a sigh of relief, turn back to your Netflix or martini, and be satisfied with a job well done.
