Jimmy Survived the Streets—Now He Needs a Chance to Survive This Tumor

For days, Jimmy wandered the streets carrying an enormous tumor on his neck.People spotted him but couldn't get close enough to help. Every day he remained out there, he was forced to live with the weight, discomfort, and uncertainty of a mass that continued to grow while he fought simply to survive.

When ThisIsHouston learned about Jimmy's heartbreaking condition, volunteers immediately began searching for him. After an entire weekend of efforts, and with the incredible assistance of the Houston Police Department Northeast Division, Jimmy was finally brought to safety and rushed straight to the emergency hospital.

For the first time in who knows how long, Jimmy no longer has to face this alone. Now the search for answers has begun. Veterinarians immediately performed an aspirate of the large mass on Jimmy's neck, which revealed round cells. While doctors suspect it could be a transmissible venereal tumor (TVT) or a plasmacytoma, it's too soon to know for certain. Jimmy still needs extensive diagnostics, including bloodwork, heartworm testing, fecal testing, a tear test, and skin cytology, so his veterinary team can determine exactly what they're dealing with and how best to help him.

Right now, even the first 48 hours of diagnostics carry an estimated cost of $915 to $1,657—and that's before any treatment, chemotherapy, surgery, or additional medical care he may need once a diagnosis is confirmed.

Despite everything he's endured, Jimmy is finally safe. He no longer has to search for food while carrying a massive tumor or wonder where he'll sleep each night. Instead, he has a team of people determined to fight for him and give him every opportunity to heal.

Dogs like Jimmy are so often overlooked because their medical needs are overwhelming. But at ThisIsHouston, we believe every life is worth fighting for, no matter how difficult the road ahead may be.

Your donation today will help provide Jimmy with the diagnostics, treatment, and lifesaving medical care he desperately needs. Every dollar brings him one step closer to answers, relief from pain, and the future he has always deserved. Please donate today and help us give Jimmy the second chance he's been waiting for.

7/16/26 Update

We have a major update on Jimmy, and thanks to your support, it's one we've been hoping to share. Jimmy has officially made it through surgery.

We received the call from his surgeon and while the procedure was long and far more complicated than anyone anticipated, Jimmy did incredibly well.

Once surgeons began operating, they discovered the massive tumor had an extensive blood supply and was tightly intertwined with the surrounding tissues. Removing it safely was an enormous challenge. Thankfully, the surgical team was able to preserve both Jimmy's jugular vein and another major vein that drains his shoulder. Because the tumor was so deeply attached, some surrounding muscle had to be removed to ensure the mass could be excised completely.

During surgery, Jimmy's red blood cell count dropped, requiring a blood transfusion. His heart rate also became a concern at one point, but thanks to the team's quick intervention, he remained stable. By the end of surgery, his red blood cell count had returned to where it was before the procedure.

The mass has now been sent to a laboratory for biopsy, and we expect results within the next 7–10 days. Incredibly, the tumor weighed 5.3 pounds. Just imagine carrying the weight of a bowling ball attached to your neck every single day. Because of your generosity, Jimmy never has to carry that burden again.

The team also placed a surgical drain to aid his recovery, and while he was already under anesthesia, Jimmy was neutered as well—one more important step toward a healthier future.

As Jimmy was waking up from anesthesia, he regurgitated and was placed on supplemental oxygen as a precaution. Thankfully, his oxygen levels have remained excellent at 99–100%, and his veterinary team is slowly weaning him off the oxygen while monitoring him closely over the next couple of days.

Jimmy still has a road ahead of him. He needs continued hospitalization, pain management, medications, careful monitoring, and we're all anxiously awaiting the biopsy results that will determine what comes next.

Thank you for standing beside Jimmy through every step of this journey. Your kindness made this lifesaving surgery possible, and because of you, he now has the chance to heal.

Please continue to keep Jimmy in your thoughts as he recovers, and if you're able, consider making a donation to help cover his ongoing medical care as we await the next chapter in his story.

7/26/26 Update

We finally received the biopsy results from the massive 5.3-pound tumor that was removed from Jimmy's neck. Unfortunately, instead of providing the clear answers we were hoping for, the results have left us with more questions. The biopsy confirmed the presence of mast cells, but the pathologist was unable to definitively identify the type of cancer Jimmy is battling. To get the answers he desperately needs, additional specialized stains have now been sent to a reference laboratory, with results expected to take another two to three weeks.

At this point, Jimmy's veterinary team is considering several possible diagnoses, including a plasma cell tumor, transmissible venereal tumor (TVT), mast cell tumor, or lymphoma. Each of these cancers carries a very different prognosis and requires a completely different treatment plan, making an accurate diagnosis absolutely critical before moving forward.

Rather than losing precious time while we wait, Jimmy's oncologist recommended beginning a treatment trial with L-asparaginase (L-spar), which Jimmy received today. If the medication reduces the amount of fluid draining from his surgical site and improves the condition of his skin, it could provide an important clue that lymphoma is the underlying cause.

Jimmy's medical team is also concerned that his surgical drain continues to produce more fluid than expected. To ensure nothing is being overlooked, they've submitted a sample for bacterial culture to rule out a possible infection.

We know this isn't the update everyone was hoping for. We wanted answers. We wanted certainty. Instead, we're facing another stretch of waiting while Jimmy continues to receive the specialized care he needs. But one thing hasn't changed: our commitment to this incredible dog.

Jimmy survived life on the streets carrying a tumor that weighed more than five pounds. He endured major surgery, a blood transfusion, and a difficult recovery. Now he's facing another hurdle, and we refuse to stop fighting for him.

Every new test, consultation, lab analysis, medication, and day of hospitalization brings additional medical costs, but we're determined to keep moving forward until Jimmy finally has the answers—and treatment—he deserves.

If you've been following Jimmy's journey, please consider making another donation today. Your support is what made his lifesaving surgery possible, and it's what will allow us to continue pursuing a diagnosis and providing the specialized care he urgently needs. No matter what the final diagnosis reveals, we want Jimmy to have every opportunity to fight for the future he's waited so long to have.

Please donate today and help us continue Jimmy's fight. Every gift, no matter the size, brings him one step closer to healing.

Jimmy has been doing so great! He had a recheck with both his oncologist and surgeon this week. His incision has healed well so his staples were removed. They were happy with how everything looked— there’s no redness, discharge, swelling or signs of infection. While his skin is still pretty flaky, he doesn’t appear to have an active infection so for now, we’ll continue using a medicated mousse until he’s able to have medicated baths.

His lymph nodes are still mildly enlarged but have gotten slightly smaller and his skin looks calmer than before.

Based on his improvement after the L-Spar treatment last week, his oncologist feels much more confident that Jimmy has cutaneous lymphoma but we’re still waiting on stain results from his biopsy to confirm a diagnosis.

Jimmy started treatment with CCNU, an oral chemo medication he’ll receive once every three weeks. Most dogs respond well to chemo, but prognosis is about 6 months.

Cutaneous lymphoma would be responsible for Jimmy’s widespread skin changes and flakiness. These issues may not completely resolve because they’re part of the cancer itself. but for now we’re hopeful Jimmy responds well to treatment and continues feeling better
