Thanks so much for all the support.

We didn't get as many answers as we expected. His echocardiogram was clear, which was better than the alternative. But, the vet kept emphasizing that his bloodwork is quite indicative of hemangiosarcoma. So, they're doing one more test for a biomarker that would indicate that there's a heart tumor smaller than the resolution of an echocardiogram. If that comes back clean, we'll just sit and wait to see if Rono's red blood cells return to normal. We'll have to wait about 3 wks due to the relatively slow turnover rate of red blood cells. We might try a relatively benign treatment for hemangio in the meantime, like a mushroom extract that we just read about. It can't hurt and it might help.

For some reason, despite our recent loss of K to osteosarcoma, I feel optimistic about Rono. Something deep in my intuition keeps saying that this is not hemangio. Perhaps it's just my survival mechanism kicking in - I honestly don't know how we'd handle another loss now with our hearts still in pieces after losing K.

Soon, I'll write a post about the loss of an absolutely beloved dog (K) and adding a very needy rescue to the family about 6 wks later. The gist will be that I still cry for K almost every day but it is wonderful to be saving a new dog (and I know that K would approve). It has helped us to look toward the future rather than only cry for the past.
