If you are wondering at what age your golden retriever will stop obsessively following you around, complete w sniffing under the bathroom door to make sure you're still alive, the answer is 14 years and two months. I just tried to talk to Tchoups while he was on his bed, and his response was very much "OMFG, seriously? You want to discuss this NOW? Because I'm IN BED. I do NOT want to go on the porch with you. I'M SLEEPING." Thanks, Tchoups.
