Summary The Chihuahua may be small but these seven pound dogs have a lot of personality. One of the most popular breeds in the world, they have captured the hearts of many people, especially the ones who live in small spaces. They are comfortable being toted around by the fashionable set as well as just curling up on their owner's laps. Unlike the other dogs that were bred for a purpose, these dogs are made to just be the perfect devoted companion. In this episode, we meet Heart, a Chihuahua with a special coat that has made her into a celebrity in her own way. Then we travel to Okinawa to meet Conan who, being a temple dog, has picked up a special trick or two befitting his position as pet to the priests. Then we meet Love in Tokyo who uses more than her four legs to get around- she uses a skateboard! She may be small but she can still sashay her way all over town. Finally, our Dog Life Adviser Momo gives us in the ins and outs of taking care of your Chihuahua's physical, mental and emotional life, with some tips on how to have fun with them too! And for a little extra thrown in, Momo takes us on a shopping trip and gets some Chis going with a special menu of yummy and healthy dog treats. All this and more on Dog Castle!
