It is a tradition for Presidents to have a dog. Obama said "That's a big issue....obviously a lot of shelter dogs are mutts like me". The dog has to be hypo-allergic like poodles. It is speculated that Golden Doodle (Golden Retriever/Poodle mix) would be the pick.
Good news is that people will be encouraged to adopt dogs from shelters and rescues. It will help to kill off nasty puppy mills.
