My heart absolutely sank to the pit of my stomach when I saw the title of this thread...so very sorry to read of this horrible news.
To me it seemed like he was
still a puppy
such a tough diagnosis to swallow at age 6 (although he could be 16, still would never be ready to say goodbye)
I know all too well the heartache you have right now, has only been just over 5 months since I lost Cosmo...still feels like it happened just yesterday...
Sending you, Mary, and Levi my very best thoughts and prayers...and please give Levi a great big hug for me.
