I'm in regular contact with all the puppy owners and I think everything is going quite well with all of them. Facebook really is a wonderful for keeping in contact and getting puppy updates.
So at the 3 month mark Orin is 43cms at the wither and now weighs 13.1kg, which is exactly where I hoped he'd be. Actually it's amazing as Kyle was 12.9kg at the same age so Orin really has caught up well. When Kyle was a week old he was 2lb 13oz, when he was 4 weeks old he was 5lb 4 oz ... Orin was 2lb at a week old and 4lb 12oz at 4 weeks. Up until their time of leaving Orin was the largest of the K litter and some of the others like Basil/Loki and Beth/Fly were really much smaller in the early days. (Basil/Loki was only 1lb 8oz at 1 week but my god did he catch up being only an oz or so behind Orin at 8 weeks)
It is fascinating, the "J" litter were numerically small but HUGE puppies, the "K" litter were numerically large and small puppies, but by the time they were/are 3 months old it's all balanced out nicely.
I know I've published this before but just for easy of finding it later, the weights and measures I have at 3 month for Ross is 12.6kg and 43cms at the wither - Loki was heavier by then at 13.8kg, Orin is somewhere nicely in the middle.
