Hi Rolo and family, welcome. I'm in the Tripawds Chat for a bit if you want to talk.

It's so ironic you are dealing with this cancer after a human family member was diagnosed with it too. As you already know, amputation can give back quality of life. While it won't cure the disease in dogs, it takes away the terrible pain of a bone tumor. The majority of dogs will bounce back and get back to enjoying what they love.

At 90 pounds, Rolo isn't the biggest dog who's ever joined us. We've had Great Danes, Mastiffs, Saint Bernards, you name it. Some have been as large as 175 pounds, even up to 200. We've had many, many dogs much larger join us and go on to live happy lives on three. So while he's larger, there's no reason why he can't have a good quality of life. Does your vet think he is a good candidate? If it helps your husband to get another opinion, that's a good move. The oncologist will hopefully give him the information he needs to feel better about the decision. Also, having Rolo see a rehab therapist after surgery will give him a leg up (pun intended!) on recovery. And the Tripawds Foundation can pay for your first rehab visit so you've got nothing to lose. We are happy to help find a therapist if your vet doesn't have one to refer you to.

Also, encourage your hubby to check out our posts about giant breed dogs, watch our giant breed videos, and come here to ask any questions. 

I hope this helps! Stay tuned for feedback from others.
