I have to say I am partial to the labs, my taylor being one. He doesn't leave my side and he always keeps an eye on me. He loves other dogs and children which is part of their personality traits. He's shedding right now but it only happens about twice a year, very smart, medium size dogs with a smile on their face all of the time. They seem to look like they're about to talk to you any minute. Either Golden retrievers or a labrador retriever. Good luck!!!
