The oncologist at Angell Animal Medical Center said he may have only a few weeks / months without treatment. Thankfully, he's shown amazing progress with a combination of different chemotherapies and seems to be back to his old ways of clumsily launching up stairs, investigating new people and politely begging for food.
If treatment is completed, he's projected to be cancer free for a year or longer, but financing the next several months needed for remission is becoming very difficult. He's always been in great health, and I have no doubt he could have quite a few years left post-treatment.
Anything that you could provide would be appreciated and extremely helpful.
