Hemangiosarcoma is a devastatingly
common cancer.
Step by step, we are progressing toward a better tomorrow for this prognosis, but right now, the best source of support we have is each other.
By donating to our mission, you can help push forward the clinical trial that may unveil the next breakthrough or come to the aid of families who cannot afford the treatment that could give them some precious extra time to enjoy with their pups.
Give in Honor & Give in Memory
The love we share with our dogs is expansive.
Giving in honor to mark a special milestone or in memory of your wonderful pet is a beautiful way to celebrate them. Your tribute to your dog can make a significant difference in the life of another.
You can share more about your story in the donation form, and if you want to, we’d love a picture of your dear canine companion to feature on our memory wall.
Additional Ways to Give
We gladly accept donations through corporate sponsorships from committed organizations and matching employee gifts to amplify the impact of your support. If you’d like to donate in another way, please contact us.
Memory Wall
In Loving Memory of Bane Bane, my sweet, special boy, you were more than a dog — you were our everything, our comfort, and the truest friend we could have ever asked for. Losing you to hemangiosarcoma shattered our hearts, but even in your final/toughest days, you showed the same strength, loyalty, and gentle/ energetic spirit that made you so special. Thank you for every moment you gave us — the excited greetings, the warm endless snuggles, the way you seemed to understand us without a single word. You filled our life with a kind of love that can never be replaced. Your presence made even the hardest days easier, and your absence leaves a silence nothing else can fill. Your life may have been cut unfairly short, but your love will stay with us for the rest of ours. We carry you with us in every memory, every quiet moment, and every place where we shared our days together. You will always be our special boy, our heart, and our forever love. Mommy and daddy miss and love you so much. ❤️

Nimbus started as our family dog, but after my siblings moved out, he became my baby. From that moment on, I made it my mission to give him the happiest life possible. I kept up with his grooming appointments so his beautiful white fluffy coat could stay as bright as the clouds he was named after. As an American Eskimo, the name “Nimbus” fit him perfectly — soft, bright, and impossible not to love.
When I took on one of the biggest and scariest challenges of my life — travel nursing — I knew I couldn’t do it alone. So Nimbus came with me everywhere. I got him certified as my emotional support animal because with him by my side, I always felt safe, comforted, and never alone. No matter how hard the days were, coming home to him made every place feel like home.
On May 26, 2025, I knew something was wrong. He told me with his eyes before anything else. I took him outside to our backyard, and deep down I knew it would be our last time together there. He sat quietly, soaking in every smell, every bird chirping, the grass beneath him, and the beautiful mountain view in front of us. It felt like he was saying goodbye to the world he loved so much. I rushed him to the emergency room praying for anything else to be wrong, but I lost my baby to hemangiosarcoma — an aggressive cancer that caused a tumor to rupture. Like so many pet owners, I had never even heard of this cancer until it was too late. Hemangiosarcoma is often undetected until a tragic emergency happens, and that is why I want to help bring awareness to it. I encourage every pet parent to check on their fur babies, trust their instincts, and advocate for their health. In honor of Nimbus, I want to support veterinary research focused on earlier diagnosis, treatment, and awareness for hemangiosarcoma, so maybe one day other families won’t have to experience this kind of heartbreak.
Nimbus was the craziest little guy with the biggest heart and the tiniest attitude. Everywhere we went, people stopped to compliment how beautiful he was — and he truly was. I miss his eyes, his little freckled nose, his frito paws, and his soft white coat more than words can explain. I still catch myself wishing I could walk through my front door one more time and see his smile waiting for me. Nimbus will always remain in my heart. And one day, I know I’ll be greeted by him again — and that will be the best day of my life. If you would like to, please consider donating in honor of my sweet baby Nimbus to support hemangiosarcoma research and awareness. Thank you for loving him with me. ❤️

In loving memory of Nimbus Maximus Velez, a strong fighter. A handsome, tough boy with an attitude. Thank you for always protecting my sister when she moved away and for making her feel happy and safe. I felt safe knowing you were there for her. Nimbus, thank you for all the memories you gave us. I still cannot believe you’re gone. We miss you so much. I love you very much.

Thank you, Milton, for loving me and teaching me how to love myself like you do. In our robust eleven years together you brought me through the darkness of PTSD, alcoholism and isolation. In the year since you left your earthly dog body, you taught me that I can trust people again; by surrounding me with human angels like Jason and all the wonderful people who work for and donate to Hemangio.
Thank you for sending your love in various ways, I hear you in the whispers of wind and see you dancing in the embers of fire you loved to chase under the sparkling night sky. May the messages you’ve shared bless someone else in their suffering and remind them that they are not alone.
“You made my heart what it is.”
I’ll see you on the other side of the River.
