Please HELP Sgt Jammer

REACHING OUT! My MARINE nephew's dog, Sgt. Jammer, who is also a Marine, has a tumor in his stomach and surgery is going to be very expensive. This dog has served our country on many tours in Iraq/Afghanistan and brought my nephew (and many others) home safe and sound - A TRUE HERO! Jammer lost a leg as well, due to blood clots, and had to be retired. My sister and nephew adopted him to give him a wonderful home to live out his days. Jammer is only 9. I know many think a dog is just a dog, but this is not just a dog and he is a comfort and rock for my nephew. We would like to do what we can to save this hero and family member and I am reaching out and asking for help from anyone who is willing and can assist.
