One of the words most famous dogs at the moment has to be Barak Obama’s Portuguese water dog which he bought for his 10 year old daughter Malia Obama, as she suffers from allergies. Obama’s daughter has chosen to call her dog Bo after her Grandfather’s nickname was Diddley, after Bo Diddley. Portuguese water dogs, which do not shed so much hair, are said to be hype allergenic, making them less aggravating to people with allergies. However there is little scientific evidence to support this claim, or to support the claim that any hyper allergenic dog breed even exists, but their non-hair shedding quality has made them popular amongst families. The Portuguese water dog is classified by the American Kennel club as a working dog, originating from the Algarve region of Portugal.
