Riley is an 8-year-old Texas Blue Lacy in Dallas, TX, who needs $1,900 for cancer treatment.

Sometimes you pick your dog -- and sometimes your dog picks you!

The latter is what happened to Brian H.

"Seven years ago, she walked through the front door of my house," Brian tells Waggle. "A sweet pup who was likely dumped. We instantly connected, and she has been by my side every day since."

Riley has been with Brian through some really tough times. He's fighting stage four cancer. She has given him great comfort and strength.

But Brian just got more devastating news, now Riley has cancer!

"I am fighting for her, just as she fought for me," Brian says.

Brian is struggling to afford the radiation treatments Riley needs to fight her mast cell tumor. He's been on disability since he was first diagnosed with renal cancer.

"I had surgery to remove my right kidney and received targeted radiation on both lungs," Brian says. "Disability doesn't pay much, and the medical bills piled up."

Please help Brian and Riley this holiday season fight their battles with cancer.
