Bunny is a rescue Lab currently being fostered by Tami Stanley of Eluess Texas. Bunny is a female Chocolate Labrador Retriever who is aproximately one year old. The description for this YouTube video says "Bunny the lab is making a splash on the Web. The rescue dog has been getting attention for a video that shows off her swimming skills fetching toys at the bottom of a 13-foot-deep pool".
According to Stanley, she "first discovered Bunny's skill when she was in the pool holding a toy underwater. Bunny held her breath, swam by and snagged the toy". The Petfinder page created for Bunny says she is "funny and sweet", "fabulous with other dogs", and "on the smaller size". I found a video on the USA Today website that says Bunny is described on her Petfinder page as "not the brightest dog". Apparently Texas Labrador Retriever Rescue Inc decided agaisnt denigrating poor Bunny's intelligence and changed the wording. The Petfinder ad now describes Bunny as "silly".
Regarding Chocolate Labs, Wikipedia says, "the origins of all Chocolate labradors listed on the LabradorNet database (some 34,000 Labrador dogs of all shades) to eight original bloodlines. These bloodlines each lead back to three black Labradors in 1880s Newfoundland. Labradors are relatively large, with males typically weighing 64-90lb and females 55-71lb. The life expectancy for Labs is generally 10 to 12 years".
Video Description: Bunny dives to the bottom of a 13 foot pool to retrieve a toy. It is quite rare for a dog to be able to hold it's breath for long periods of time underwater. Video posted to YouTube on 7/16/2013 (2:01).
