All are sweet, playful and friendly. All like being held and will lay in your arms and let you rub their belly. When someone approaches their play yard, they all come running to greet you. I am no puppy expert, I really do not see a dominant puppy. Here are a few notes on each of them.
Pecan Sandy - very playful, never tires of play, play, play
Sugar - funny after she plays for a while with her siblings, she finds a blanket to curl up and chills just watching the rest
Oatmeal - really loves your attention, will look up at you and whimper, once you pick her up, she gives you a few licks and is quiet
Oreo - also loves your attention and sometimes will look at you and give a little whimper to be picked up
Snickers - the smallest, not quite as energetic as the others but still enjoys wrestling with his sisters, likes to curl up in you neck
Everyone who meets the puppies comment on how sweet they are. They are only 6 weeks old but at this time do not have the crazy energy that several other litters of pups I have see have. I have read that puppies should meet 100 new people by the time they are ?10weeks. Well, I live in a large neighborhood and they are on their way with all the visitors and kids stopping by to see them.
As they get older and I notice more individual characteristics, I will add more comments to these notes.
