Richard, I don't know what breed that pup is, would guess Samoyed like some other members have said, but whatever it is, that's a beautiful pup.
I've been learning something new about dogs the last day or so myself. My daughter has a pair of Maltese and she's been afraid that while she's at work, that little female Maltese would have her latest litter. Now I wouldn't have considered that anything to worry about, but my daughter's been telling me that it's not uncommon for a female Maltese to cut the umbilical cord too short and let a pup bleed to death or for the mother to accidentally pull the pup's innards out and kill it. So my daughter has been wanting me to keep an eye on the dog during the day. I told her I know nothing about midwifing for dogs; just a little experience with cows and goats.
Well, sure enough that little dog had her first pup of this litter just about the time my daughter walked in the door yesterday evening. First and second pups were taken care of just fine, but on the third one, the mother cut the cord too short and my daughter couldn't get the bleeding stopped, so I took a one hour old pup to the emergency animal clinic. The vet put in 3 tiny stitches and told me the mother would remove them in a few days. Well, she removed them overnight, but at least today all 4 pups and the mother are doing just fine.
I just went and checked the pups again. My wife loves those little dogs, but she's afraid to try to take one of the pups from the mother /forums/images/graemlins/laugh.gif, so she can't really check them. I've tried, unsuccessfully, to tell her that little dog is not going to bite; she'll try to push my hand away with her nose, but never growls, snarls, or makes any attempt to bite anyone. And the only time she barks is when she wants to get your attention to play.
