Wish I could help you but I think that it depends on the yorkie. I have two boys, one month apart in age, got them within a week of each other and two more totally different pups you could not find. Gar is loving, affectionate, hyper, refuses to perform, etc. Benni lives to please, yet is independent, does not like to cuddle as much, no where near as affectionate, yet has a crazy personality. I think again that each one has such different characteristics that it is impossible to have a "development chart" on any of them. Not only do all yorkies look different (ears up/down, range in color from black and gold, to all gold, to platinum to silver, size anywhere from 1 pound to 20), but they all have different personalities. |
