Once you've gotten your dog to master basic commands like sit and stay, it can be fun to train them to perform more advanced tricks. Or maybe even train them to do household chores like fetching the mail and loading the dishwasher.
This woman, however, took a less useful but more entertaining route. She has trained her pup to meow like a cat. At first, when told to meow, he barks instead. Eventually, though, he masters the meow, and receives a treat for his efforts.
Once he really gets the meow down, this could become a great parlor trick.
