Halo
Dumped With a Tumor the Size of a Soda Can — Halo Is Fighting for More Good Days
Missoula, MT • WOOF TRIBE SANCTUARY & RESCUE INC
Halo was found abandoned in the fields of Modesto, alone and in terrible condition. Her body told the story of a life spent surviving, not living. The most shocking discovery was a mammary tumor the size of a Coca-Cola can — heavy, painful, and impossible to ignore. Woof Tribe Sanctuary & Rescue stepped in immediately. Halo underwent emergency surgery to remove the massive tumor, but that was only the beginning. She has since endured three major surgeries: tumor removal, repair of a hernia through her abdominal wall, and a spay with additional mass removal. Through it all, Halo has shown incredible strength. Sadly, the biopsy confirmed what we feared — Halo has been diagnosed with aggressive cancer. Despite everything she’s been through, Halo is a very special dog. She’s captured hearts and even developed a devoted following on Facebook. People who meet her fall in love with her resilient spirit and gentle soul. Halo’s past was not kind. We believe she was used as a breeder dog and dumped when she showed signs of mammary cancer, likely caused by never being spayed. She didn’t even know how to “dog” when we rescued her. She had learned to survive — hunting for food, fighting off coyotes and snakes, and seeing other dogs as competition instead of companions. She needed professional training just to safely live with other dogs. Slowly, she learned that dogs could be friends, not threats. That transformation alone was a huge victory. Now we are fighting to give Halo the best possible quality of life for the rest of her days. To do that, she urgently needs: • Genome testing on her tumor to create a custom chemo pill plan • Baseline staging care (bloodwork, X-rays, ultrasound, oncology consult, mistletoe therapy consult) • Remaining board-and-train costs Once stabilized, Halo will move to a loving fospice home where she will receive chemo pills, mistletoe therapy, and immune support — all focused on comfort, happiness, and making every day count. Halo survived abandonment. She survived cancer surgery. She survived a life where she had to fight just to exist. Now she deserves gentle days, soft beds, kindness, and love. Your support helps us give Halo not just more time — but better time. Time filled with comfort, care, and the peace she’s never known. Help us make Halo’s remaining days her very best. 4/22/26 Update Halo has already endured so much—abandonment, a massive tumor, three major surgeries, and a diagnosis of aggressive cancer. Now she faces her next critical step: cancer staging tomorrow. This testing will tell us how far the cancer has spread and guide how we keep her comfortable and give her the best quality of life possible. We urgently need to raise funds to cover her care. And we’re especially worried—a new abnormal nipple has appeared near her original tumor site, raising concern the cancer may be returning. Time matters. Halo has fought so hard to survive and is finally experiencing love and safety. Please help us give her the care—and the peace—she deserves. Every donation makes a difference. 4/29/26 Update We are beyond grateful to share that because of your generosity, Halo will now be able to receive the immediate chemotherapy she urgently needs. After Halo’s recent cancer staging appointment, we received devastating news: her aggressive cancer has spread. It was a heartbreaking blow after everything this sweet girl has already endured — abandonment, a massive mammary tumor, three major surgeries, painful recovery, and finally learning what it means to be safe and loved. But thanks to you, that devastating news did not become the end of her story. Because donors stepped forward, Halo now has the funding needed to begin urgent oncology treatment in an effort to slow this disease, push for remission, and give her the best possible quality of life moving forward. Your kindness has given us something priceless: options, hope, and time. Time for treatment. Time for comfort. Time for Halo to keep discovering the gentle life she was always meant to have. When Halo was found alone in that field, discarded when she needed help the most, no one could have imagined how many people would come together to fight for her. But you did. You saw her worth. You believed her life mattered. You chose compassion. Most importantly, because of you, Halo does not have to face this next chapter without help. She is finally surrounded by people who refuse to give up on her. From all of us at Woof Tribe Sanctuary & Rescue, and from sweet Halo herself, thank you for making this lifesaving care possible. We will carry your kindness with us into every treatment, every appointment, and every hopeful day ahead for this brave girl. Halo’s fight continues — but thanks to you, she gets to fight. Thank you for being part of her miracle.
Bubba
Bubba is a 4-year-old Mastiff in Thornton, CO, who needs $5,000 for Chemotherapy.
Thornton, CO
When a veterinarian says those dreaded words, "Your dog has cancer," time stops. Your head spins. You vow to do all you can to help your pet. Then you get hit with the bills. Danelle B. is trying to deal with that agonizing situation right now. Her beloved dog, Bubba, is battling cancer right now. His diagnosis was shocking, especially since he is so young. "Bubba had a baseball-size tumor along with a foot of his small intestine removed about a month ago, and we just got the results back that he has lymphoma, and it has spread throughout his lymph nodes," she tells Waggle. The unexpected expense has drained her bank account and racked up thousands of dollars in bills. Danelle says Bubba is such a gem, so friendly and welcoming to everyone. Chemotherapy is the only treatment that will save him. Danelle and Bubba are so thankful for any assistance. "Please help me save Bubba's Life," Danelle pleads. Danelle rescued the cute Mastiff when he was just nine weeks old. "He had the brightest green eyes and sweetest personality," she adds. "I went to an adoption event at a local PetSmart and fell in love immediately. Initially, when I first took him home, I wanted to give him a strong name like Thor or King, but I couldn't help it when Bubba would come so naturally. He is now Bubbies or Bubba Lou." "I was only able to afford the emergency surgery with credit cards, and help from my mom and dad. After already spending over $7,000, I am in a position where I can no longer afford further treatment without help," Danelle says. Bubba now needs eight rounds of chemotherapy and is being treated by Dr. Oberthaler at Treeline Veterinary Office in Boulder, CO.
