got my weim last december he was 12 weeks when i picked him up, had him for a week then we got hit with a blizzard lol, other than standing out in the freezing cold with a pup trying to get some training in,,, it didnt really bother me much plus by spring he was well ready to be worked on birds and so forth. he was well ready to hunt by september and i had a very good 1st season with him this year. he was 13 months old on the opener here in iowa and pointed well and held his birds nice and tight, i have bought pups at just about every time of the year and personaly i kinda like the winter pups, just cause i know they are gonna have a good head on their shoulders the 1st season and it helps if you get a pup that is alittle slow to develope it will give ya alittle extra time to work through issues, im picking up another weim at the end of febuary from a repeat breeding and he to will be about 12 weeks old, i will have to get on the stick quick with this one.
