Summary When it comes to dogs described as man's best friend, no other breed quite fits the bill as well as the Labrador. This even tempered, family oriented, always ready to please dog is a staple in a many households all over the world. Labradors love the water. This is due to the fact that they were originally bred to haul next for fishermen in Newfoundland Canada! Its intelligence, gentle and retrieving nature has given many of its breed the proud name of 'working dogs'. In this episode, we visit a very special place at the foot of Mt. Fuji where some special Labradors have gone to retire. Then we get a little wet with Chel, a water rescue Labrador. Next, we meet Marine, who uses her optimized sense of smell as a cancer sniffing dog. She is helping develop a technology that detects cancer in patients non-evasively. Finally, our Dog Life Adviser Momo gives us in the ins and outs of taking care of your Labrador's physical, mental and emotional life, with some tips on how to have fun with them too! And for a little extra thrown in, we attend some dog obedience classes to get some basics on the importance of this first step to well mannered adult dogs. All this and more on Dog Castle!
