I'm so sorry for your loss
I know what's it's like, we adopted a Pit mix puppy from a shelter a few years ago and lost her a week later due to an illness.
Awww, my Beagle's name is Darla.
I agree that you may want to start your search on Petfinder.com. Local shelters and some rescues post adoptable dogs there, so you may be able to find a dog that needs a loving home as much as you need a great dog
. Good luck to you
