Bladder cancer in dogs is sneaky because its early signs, straining, blood in the urine, frequent urination, look exactly like a urinary infection. When 'UTIs' keep coming back or won't clear, that resemblance is the clue worth following.
Bladder cancer in dogs (most commonly transitional cell carcinoma) causes signs that mimic a urinary tract infection: straining, blood in the urine, frequent urination, and accidents. It's often suspected when a 'UTI' keeps recurring or won't respond to antibiotics. Diagnosis is directed by your veterinary team; catching it earlier keeps more options open. Treatment is directed by your vet and oncologist.

Why it masquerades as a UTI
The most common canine bladder cancer, transitional cell carcinoma, irritates the bladder lining and produces the exact signs of a urinary infection: straining, blood in the urine, going more often, and accidents. Many dogs are treated for repeated UTIs before cancer is suspected, which is why persistent or recurring urinary signs deserve a closer look. [1]
The signs and the pattern
Blood in the urine, straining to urinate, frequent small urinations, and house accidents, especially when these keep returning after antibiotics or never fully clear. That 'UTI that won't quit' pattern is the tell that separates it from a simple infection. [2]
Diagnosis and options
Because it mimics infection, diagnosis takes specific steps, urine tests, imaging, and sometimes specialized testing, directed by your vet. Treatment may combine medication and other approaches; because of tumor location, surgery isn't always straightforward. Your oncologist explains what fits your dog. We never diagnose or set doses.
Where a pharmacy fits
If your veterinary team prescribes a medication we carry as part of the plan, we can supply it in collaboration with them. Diagnosis and treatment stay with your clinicians.
