Does spaying increase cancer risk like hemangiosarcoma in large dogs?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 9 years and 2 months old | 4 lbs

Is the increased risk for hemangiosarcoma after spaying only for large breed dogs? I don’t want to risk precious getting it & it’s really scary

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Hemangiosarcoma is a cancer seen most often in large breed dogs like German Shepherds, Golden retrievers, labs and large mix breeds. I do not think all the evidence is there to say that spaying or neutering CAUSES cancer. I think spaying Precious is a personal decision for you. Everything in life comes with risk, you need to weigh which risks you are willing to take. Ultimately it is absolutely fine if you do not want to spay her as long as the risk of an infected uterus is a risk you can accept. However small it is. Have a great weekend!
