My large dog has bone cancer. Are there alternatives to euthanasia?

Updated on September 23rd, 2025

Pet's info: Dog | Newfoundland | Male | neutered | 4 years and 9 months old | 190 lbs

I've got a vet... whom believes I need to "put down" my 5 year old Landseer. He has bone cancer in the left/rear quarter. Sadly, at 190lbs, it is seemingly impossible to amputate. He's oversized and has been on thryoid meds for last 3 years. He is happy, alert- and aware of everything...but can barely get up, and walks have been discontinued. I cannot own up to this, without thinking there is something I can do to alleviate this mess.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry about Chunk's diagnosis! This is a terrible situation!

If Chunk is having such a hard time now, it will likely be the same if the rear leg was amputated. Amputation is just palliative unfortunately, meaning it buys you and the pet time. Most bone cancers have microscopically spread by the time they are diagnosed. If Chunk's tumor is a fibroscarcoma then it is slower to spread and he could get more good time if he loses weight and is able to learn how to get around with 3 legs.

So, if you are not ready to give up or give in to the situation, ask to have a biopsy done of the tumor so you know what cancer you are dealing with. If it is a fibroscarcoma then amputate and deal with losing the weight afterwards. If it is osteosarcoma then I think putting him down is fair.

I am again very sorry that this is happening to you and Chunk. He is too young!
