It was the other way round with me, Set. My dog helped ME out!
Long hospitalisation and recovery led to me getting into a semi vegetative state at home. My old dog had died about a year before, and my wife decided it was a good time for me to have another friend.
We went to a Rescue, and saw many dogs that were yapping or excitable.
Now, normally I would have taken such a dog, as I would have felt the urge to turn its life around and make it a happy secure member of the family, as I had with my previous two.
But this time, I was only about 50% recovered, and we looked for something a bit quieter.
This scrawny mutt of a greyhound came across to us, wagging its tail and licking my hand through the fence. It immediately leant against the fence, and enjoyed a quiet fuss from us for a few minutes.
SHE chose US !! I'm positive of that, and we have been inseperable for a few years now.
Speaking to other owners of "retired" Greyhounds, she is nothing out of the ordinary, and she certainly helped me through my recovery, by forcing me to get out of the house on gentle Country walks.
In return, we have "fed her up" (stick thin, when we got her, no muscle on the legs at all, and spine clearly showing) and spoilt her rotten.
