How about all the dogs that die of cancer that were never diagnosed?
Do you think everyone takes their pet to the vet for diagnosis and treatment?
Think again…
Consider “over diagnosis” many pets are diagnosed or misdiagnosed and sometimes there are no treatment options no matter how much you spend for the tests (100s, 1000s)

Something to think about and discuss with a veterinarian, someone that has actually examined your pets and knows their history.
Btw: I think you meant to say Chihuahua
