Corgi owners, when did your dog reach full height?
 

I have a Corgi/Shepherd bitch almost 6 months old. She has way more Corgi than Shepherd in her. Kind of looks like a Corgi wearing a German Shepherd fur coat. She is close to 30lbs in weight. Assuming she follows Corgi growth patterns can I expect her to get any more leg length? Is a year old Corgi any longer than at 6 months?

Can't speak for Corgi's, but one of my mini Dachshunds was 6 months old when we adopted him. He had achieved his full length - further growth was limited to filling out of his body. Lady I met in line at store had her Corgi with her - was 1 year old - apparently same with him. But since your pup is a mix, perhaps there will be further growth. My just turned 2 Eskimo has a long back - and I would say had also just about reached full length by 7 months - age he was neutered. I remember because his little jacket made him look like a white wiener with a bouffant at both ends. Careful with your Corgi's back.
