Shele,
I'll check the board regularly, it is really good to have others to talk to. What is it about "12"? We took Shelby to the first emergency vet center in May, on her 12th birthday (that stunk!). This has been really hard on me becuase Shelby is my first pet, my girl, my responsibility...we've been through a lot togther! My first family pet was a sheltie mix who was with us for 19 years. Yes, 19 years! So in my head a 12 year old dog is really very young, at 12 our sheltie was still a puppy!
I'm glad Ryle is doing well on his current treatment and that he has such good care. Let me know how you're all doing and if you find anything else in your online reasearch...I will as well.
