Annie, I am so sorry for your loss...I know what that sort of heartache is like and I am sincerely sad for you.
I hope that you will consider another puppy, if you are inclined to do so, because when we lost one of our puppies (I am a breeder) the only thing that helped to ease the pain was to sit on the ground and have the remaining 9 puppies climbing all over me!
There is no sorrow that a puppy can't ease...
None will replace your dear Hannah, of course, but human hearts are big...certainly big enough to put another dose of Doodle love in there!
I am originally from Utah...and I am now in northern CA...so I have a special affinity to you and certainly do welcome you to our forum!
Please contact me privately, if you'd like...I'd enjoy chatting with you.
