Hi all I posted a question about buying a sheltie here about 2 months ago and you all were super helpful. We decided to go with him and he's been such a joy! Here are some pics of him from 12 weeks to now: http://s1383.photobucket.com/user/Tiffany_Engen/slideshow/ I was looking at some old posts on sizes and was wondering how big you all would estimate he'll get? He's currently 21 weeks and 13.5", 16.5 pounds so he's a heavy boned boy! At 4 months he was 12 pounds and ~11.75". His weight is going up ridiculously fast but he's just super long right now (I've had someone ask what kind of corgi mix he was). His legs have never seemed super long and coyote like (like in some of the pics that have been posted here) and his adult hair is growing in super slow and longish compared to others. He still has a bunch of puppy hair! Do you think he's just starting his growth or he's going to slow down soon?
