Japanese Spitz! Probably going to be around 20-25 lbs fully grown. He's a monster. Our other spitz maxed out at 16... Believe me, I'm going to wear this with everything. American Apparel summer crew over a Silent tank.
Haha, they have their crazy moments, but overall aren't especially active. One of our neighbors has a shiba and they can only keep up for like 20 mins before giving up an trying to escape.
When my wife and I take them jogging, after about 2-3 miles they just find the nearest tree and collapse, refusing to move.
