Hi, has anybody heard about the increased risk of a bone cancer called osteosarcoma, when neutering a standard/large male before one year? I have a standard goldendoodle, and read that osteosarcoma is the third most common cause of death in golden retrievers. If it's true that neutering before he is one increases the chance of him getting this disease, I don't want to risk it. Max is 5 months old and was scheduled for neutering yesterday, when a friend told me about the increased chance of bone cancer for him if I go ahead with it. So I held off with the procedure until I know more. I would be grateful if doodle owners could help me out here, especially since I am a first-time puppy owner.
After re-reading the linked discussion I just had an epiphany about my rescue Clancy. Clancy was neutered (we think) at either 6 months or 13 months depending upon which birth date you want to use. Clancy is not an aggressive dog but he is attracted to and attracted by unneutered males. They try to dominate him and he allows it but as soon as they let him up, he goes after them. He also goes over to the unneutered males, thus drawing attention to himself. This probably has something to do with his neutering age as well as his need to survive on the street. My DIL's male whippet was not neutered until age 5. She can not take him into dog parks without checking what dogs are there because he will pick fights. The neutering helped the marking, and some of the aggression, but not all. He and Clancy tolerate each other but are NOT BFFs and never will be.
This isn't about bone cancer but it factors into when to neuter for me.
Our lab mix just died from and aggressive bone cancer at age 12. He was neutered at 6 months.
