His body image looks perfect. Our vet would tell us not to worry about weight in numbers, rather more body composition. Ace was less than that at 12 weeks if I'm not mistaken. He is now 50lbs at 15 months and is very agile and a very fast runner!
He ended up being 19.1 pounds at the last check up 13 weeks. My vet keeps making comments about his health and how he must've come from good stock. He's not seeing any of the normal respiratory or breathing issues. Bite is good, eyes are clear and tail is good. I'm very happy.
