@officerripley I hate hearing this. I am so very sorry

I get what you are saying about no more dogs, if something were to happen. I have never been without a dog - big guard type dogs as I was raised on a farm and have always lived rural. It has always been a huge comfort to have the dogs greet me at the door.
When I lost my Rottweiler to bone cancer in 2022, I did not get a companion for my Catahoula/Pit Bull. He was happy as long as he could sit on Husband’s lap.
After husband passed, the dog went into a deep depression. I went to the Animal shelter. I did not come home with the senior dog I was interested in, as it was a male used to being alone - I came home with a dog they said was 4 or 5 years old - much younger than I wanted for all the reasons you say.
I have rescued horses, dogs, and cats my entire life. It didn’t take me long to figure out this dog was a long three year old, not a long four year old, but I wasn’t going to take her back. She is the most joyful-joyful dog and has got Sheldon out of his doldrums whether he likes it or not, lol. She is a purebred Blue Pitbull that was confiscated from a backyard breeding situation. She had been having pups since her first heat


. I can’t remember any of my dogs being as joyful as she is, nor did they have such a great sense of humor.
My last two horses are now 30 and 28-ish. If I go ahead of them, it’s in the Will they get PTS’d and so does the 12 year old Catahoula/Pitbull. I will give my brother the option to take the Pit Bull (he currently has Pitbull/mix he rescued) or have her PTS’d.
My point to all that is, maybe you could look for an older dog who lost its humans and needs a soft landing and make arrangements in your Will for the dog to be PTS’d if it would come to that?
