well he is 2.6 years old around 80 but I haven't weighed him since he was 1.5. Believe it or not he was about the same size now when he was about one but he had parvo and almost died. Since then he had a real issue gaining weight dut to the fact that the linen of his stomach was never the same. But due to a good and exspensive dog food EVO he is on his way back. If you notice in the pics my dog has great definition that is due to the running that he does all on his own . one day I took him to a track and ran him around for a few minutes. took him home. And all of a sudden he started to run in the backyard all by himself to the point he developed his own dirt track. hours and hours he runs in circles. SO running your dog will give him the muscular look your looking for and a high quality dog food . Evo is very high in protein your dog may be to young for it. It is recomended that you dont feed your dog evo every day. BUT BUY THE LOOKS YOUR DOG LOOKS GREAT.
