His coat looks like my Female Golden's coat. Her tail didn't really start to grow out until she was a year old. But Her uncle on the other hand, he had a full flag, fuzzy butt and fluffy chest by the time he was 5 months old. Good luck, they are a hand full but so worth it. BTW, I have found that weight control gets to be a bit of an issue even if they have rediculous amounts of excercize. The way I do it is by using Blue Buffalo Blue Wilderness. I buy both the regular Large Breed Adult Chicken formula and the Large Breed Adult Chicken weight control formula. If they start putting on a few pounds then I cut their food with the weight control food 50/50. Tastes the same to them and they still eat the same amount of food, but stop the weight gain. If only it was so easy for people huh? lol
