I've had 2 very large Golden Retrievers. Both were house dogs, and my house has a lot of antique furniture, so space is at premium. Neither dog EVER knocked over anything. They were amazingly graceful while weaving between furniture legs, etc. The only thing I had to watch for was the tail An excited Golden can sweep your coffee right off the coffee table with their tail.
BIL had a pit-lab that was like that. It was like having someone taking a ball bat to your shins when he started wagging...
