I'm not quite that old but personally… and I have thought about this, I wouldn't necessarily let that my age restrict me from taking on another dog. Owen is just under a year old and God willing he lives a typical Heeler life span, I'll be in my mid-late 70's when he gives up the ghost. At that stage I probably wouldn't bring on another puppy but an adult rescue is something I hope I could seriously consider, health permitting. So far I've dodged significant health issues. "Inshallah" I'll still be in decent shape in my senior years, and that is NOT far off.
We were taking on senior rescue cats for a few years and I can assure anyone interested in going the senior rescue route that there is
NO shortage of those animal at shelters, be it dogs or cats. At the SPCA seniors are pretty much on death row, just waiting to be euthanized. They are old, abandoned, lonely and confused. The good folks at my local SPCA let seniors roam the shelter a bit more than the general population as their execution date looms closer. They get special privilege. SPCA employees have a strenght that is hard for me to even fathom.
So when I'm on short final to the Pearly Gates, and most of my kin make it to their late 80's/mid 90's, I intend to take on some old discarded mutt. Like I said, this is something I
have contemplated. Moreover I'm blessed with an amazing wife just over 10 years younger than me who can manage the flock for some years when I'm gone. Even without a presence like that in one's life a "pass the torch" plan can be implemented with trusted family and friends. IIRC correctly
@solomon you have kids or nieces/nephews so they can lead the charge. I have
not been that similarly blessed.
All that being said
@solomon, I advise taking on a senior rescue dog when the time comes to fill that void. Let's not kid ourselves here, your pup is
really getting up there. Reality is imminent. It seems like you're doing a stellar job keeping your old boy active and in the fight. That dynamic supports both your Lab and you yourself. Clearly you're a man of great love of pets. You'll need to continue that interactive dog presence when the void presents itself. Hit an SPCA shelter ASAP and go rescue another old boy/girl literally from the jaws of death. Give them another 2 or 3 years of well deserved retirement. You'll be their only way out.
