We had a Golden when I was growing up, she was a great dog. She never had those issues but my parents were idiots and fed her stuff you shouldn't give to a dog, so she had kidney and bladder issues now and again.
I've tried to learn my dog's limits. When she overdoes it, it's obvious. She spends the rest of the day lying in a corner. If she has to get up for some reason, it's a real effort to drag her back end up.
