Remus is our 9ish year old German Shepherd who rescued us five years ago when he just showed up out of the blue at the gate of the property we were living on in a rural area at the time. After attempting to find his people, we ended up adopting him and have loved him like family ever since. He came just in time to help us say goodbye to our 15 year old boxer when she sprouted her angel wings a few months later. It was very clear he had never had any training, been on a leash, or been socialized. We were able to solve some of his mysterious past later on and are so happy he found his way to us. He has come so far and is now the sweetest, lovable, goofball of a dog.

In the beginning of November he developed a limp pretty much over night at which point we discovered a small lump in his front left paw. After x-rays and a second opinion from an oncologist he has been diagnosed with "maybe" osteosarcoma. I say maybe because though it's likely that's what it is, they won't be sure until they biopsy the mass. They recommended waiting until amputation to biopsy as they advised the results can be inconclusive from just a small sample. I was told either way, whether its osteosarcoma, another type of tumor, or even a fungal infection the best recourse would be to amputate the full leg. 

The surgery is scheduled for tomorrow and as you would expect, we are both sick with worry for him, but reading everyone's stories has been such a comfort.

Any words of comfort and advice would be greatly appreciated!
