I lost Jasmine almost a year ago due to thyroid cancer and she was only 8 yrs old. Sara has been fighting mast cell tumors for over 2 years and thankfully she is happy and currently in remission. I am constantly trying to figure out what I did to have two dogs with cancer. They are two different types of cancer so the vets say it is a fluke but I still think there is something else. What I fed them, any household chemicals, environment, vaccinations, etc. There are too many young dogs with cancer. Does anyone else wonder this? I am new to the site and really do not know where to post this. I think it would be a good idea to have a cancer forum to try to dig into some common ground that might shed some light on this any ideas?
