That's interesting... definitely good info for any future dog owners. I did indeed get her spayed at a later age, smhSorry too
Was actually thinking of getting one soon and was doing some reserch came by this info on female dog and cancer. The cancer numbers are ceazy high on non spayed dog. Might be useful to other future dog owners.
Mammary tumors are more common in female dogs that are either not spayed or were spayed after 2 years of age. The risk of a dog developing a mammary tumor is 0.5% if spayed before their first heat (approximately 6 months of age), 8% after their first heat, and 26% after their second heat. Cats spayed before 6 months of age have a 7-times reduced risk of developing mammary cancer and spaying at any age reduces the risk of mammary tumors by 40% to 60% in cats.
More than a quarter of unspayed female dogs will develop a mammary tumor during their lifetime. The risk is much lower for spayed female dogs, male dogs, and cats of either gender. In female dogs, 50% of mammary tumors are benign and 50% are malignant. However, few of the malignant mammary tumors are fatal. In contrast, over 85% of mammary tumors in cats are malignant and most of these have an aggressive biologic behavior (i.e., mammary tumors in cats tend to be locally invasive and spread elsewhere in the body).
Don't let it change your mind though or make you second guess getting one. I wouldn't trade the years I had with my dog for anything. It's a sad ending, but the journey was great. There's no one else in the world who will be happy and excited to see you EVERY TIME you come home but your dog
