My condolences on your loss.
We use rescues to get dogs too.
Also have had 2 rescue horses.
The dog we have now is a rescue, a chocolate lab mix who is 2.
One of our dearest dogs was of unknown age but I knew he was at least 6 when we got him. He was wonderful.
Sorry for your loss.
I don’t usually post on this thread, but saw that sweet pic of your beloved pet and had to say am so sorry for your loss. Pets become family!
