Rocket's uncovered veterinary expenses

My name is Kellie and my good friends Donna and Mark's pup Rocket has just been diagnosed with lymphoma. I am raising money to alleviate some of the cost of his uncovered expenses. They are good people who live within their means and are retired. Rocket is their baby and is one of Lady and Rollo's best friends. This is heartbreaking and I don't want them to have to bare the burden of the cost here. Dog lovers can understand how this must feel.

Any amount is appreciated. Thank you!
