Vet Costs for Oz

I have very mixed feelings about doing something like this, but I don't feel like I have too many options.  Oz, my much loved Australian Shepherd, is in need of fairly urgent surgery, and it is beyond my means at this time, so I am reaching out to ask for help.  

I absolutely adore this guy.  I can't tell you how much it means to me to be able to try to save him.  I have come a long way from the little girl who was completely terrified of dogs.

He has a mass on his spleen, which needs to be removed as soon as possible, as it is causing harm to his other organs, and making it difficult for him to maintain proper blood flow, or digest food well.  Because of the ways that this has already affected his body, he also needs blood.

In the event that there are any funds remaining, they will be donated to an animal related cause.  My endless thanks to anyone who is able to help.
