Dont worry, I'd never let him go over the top, as much as he'd like to, I know what could happen if he does, he is being really good, the only time we have problems is when me or my OH come home cos he gets so excited but we are managing to keep him from going mad like usuall, we are very lucky that we never have to leave him on his own as he goes to my parents when we are out at work so he always has someone to watch over him to make sure he is takinh it easy, he just has soo much energy to burn, though he's getting slightly better now as the vet has allowed 3 x 25 minute walks a day now, he's still on a short lead, but it's a damn sight better that 3 x 10 minute walks a day!!
