I hate to say it but I fear Pet Friend has ulterior motives here -- why such an open-ended question? "save" -- as in treat or prevent?
Honestly it's a rather insane type of question that can't have a dollar value attached to it. Because is it cut and dried to the point that you'd spend $0 - $99 but if it were $100.01 you wouldn't? What sort of guarantee do you need in advance?
No one knows where such costs may end up or how long it would take, and whether successful -- or maybe not well tolerated by the dog. And it might depend on the type of cancer, type of treatment, and the individual dog.
We treated Muffin the Intrepid for MANY reasons. He was a therapy dog and ALREADY was working with both deaf and handicapped children, ***including*** children being treated for cancer. He had a huge drive to survive and was just one of those dogs who was going to survive and that was IT. And ultimately when he left this earth, he did it on his own terms then too.
But for him where did we start counting cost? He was likely one of the most expensive dogs in history but THAT started when we rescued him and he had horrific demodex and I "learned how" to deal with demodex back before I could spell it.
Along the way were the horrific ear infections and then later the bi-lateral ear ablations because the infections weren't treatable any longer (thank you, Bad Vet who did everything wrong).
Soooooo we've already spend thousands in the years we've had this dog so when he gets a bump under the tip of his willie that needs to come off, am I gonna say no? Of course not.
We knew we didn't get clear margins -- and I'd already put my bonuses for the last two years in savings. So when we got the opportunity to combine TCVM with chemo (both up at the University of Florida) at incredibly reasonable rates we had the money so we did it.
Or ... would I rather explain to the kids at GKTW's local gathering that no, Muffin didn't GET chemo because we weren't going to spend the money on a dog? We just put off new cars another couple of years.
Ok -- let's go to Ms. Socks -- I knew she had cancer but she already battled SO hard with the enlarged heart and crappy lungs. She wasn't a surgical candidate, and it wasn't painful and she was 14 or 15. So I put her on a cancer diet to buy her time, and she was completely pain free. When she was 16 1/2 the nodules began to rupture and THEN she was in pain. THEN she indicated she was done.
Yes, she was another therapy dog, but a completely different temperament and even tho she, too, loved kids it was a different personality and drive. I respect each dog as an individual too much to not take that into account.
I just plain can NOT answer that question. Because it HAS no answer. It depends on the kind of cancer, the kinds of options, the individual dog and what we can and can't do.
It depends on my individual finances at the time -- and what can be done realistically.
I CAN *SAY* that I do spend a lot of money trying to minimize my dogs collective chances of GETTING cancer.
I home-cook for four dogs -- they don't eat kibble preserved with BHA< BHT or ethoxyquin. They don't get much grain so it keeps the body environment not conducive to the growth of cancer.
They don't get many vaccines, and I'm always vigilant about the immune system -- and 3 of my 4 have serious immune issues either because of past history (Billy), age (Kee) or genetic problems (Tinkerbell/demodex).
Can I 'win' - no but I can stack the odds a bit. But I wish I knew why "Pet Friend" was collecting information.
