What I meant was he would not have been actively subjected to physical negatives from the babies.
I can perfectly understand the upheaval and difficulties babies and puppies combined might create.
the owners would have known a baby was on the way, in fact probably known it was twins when he was born, let alone when they collected him.
I have puppy owners who have had a pup when the wife just discovered she was pregnant (it did worry me but they had been waiting for pup around a year so not a rush decision), and also one couple had twins when Inka's brother was only just over a year old (but very dog savvy family).
Both families have found the dogs (interestingly both males) marvellous around the children, but obviously babies are hard work, and a puppy may just be too much on top. I did spend some time expecting the 'I can't cope, can you have him back' phone call. In fac t the one family have just had their second child, with the dog only 2 1/2.
Breed does make a difference as well as individuals. I chose this breed (pretty bomb proof and adaptable) when I myself had very young children, rather than have another puppy of the more sensitive herding breed I started with.
What I am saying though is with this dog the OP mentions being really only a puppy at 12 months it is not too late to socialise it properly and safely to children, as it does appear to be fear. We all know that many dogs view children positively due to the association with dropped food ;) Some breeds like my own seem to have a natural affinity even without being around children at all.
OP mentions little dog, and of course the small breeds may have more issues generally with socialisation with kids, bigger dogs etc, as they are more vulnerable.
