More likely, your dog beat cancer with SRT, but I wholeheartedly agree with your strategy of throwing everything but the kitchen sink at it.  Cancer is by definition quickly reproducing cells and therefore quick to adapt to a threat, so a single therapy is unlikely to be successful.  I learned a bit about cancer and its treatment while my two legged friend of 40 years was dying of glioblastoma.  The human medical community is so conservative (and afraid of malpractice suits) that they do not deviate from "the protocol", even if it has been unsuccessful for thirty years.  Median survival on "the protocol" is 14 months, yet I found tons of blogs by individual survivors adding a multi pronged attack of diet and supplements, illicitly obtains HIV meds, or SRT and outliving the median by five years or more with a quality of life not enjoyed by those on the standard protocol even for 14 months.  My friend could only get into a clinical trial after failing on the standard protocol, and then the trial was about collecting data for one potential therapy (which Big Pharma could patent), not about the patient.  Oddly, even though SRT was invented to treat brain tumors, it is almost never used for that, was never offered or mentioned to my friend during the 14 months that they monitored his surgically removed tumor returning and eating his brain.
