I don’t do dog parks either. And I let my females go through one heat before spaying, if they are going to be spayed, which is by far the majority of females I have had. I have had a spayed female get bone cancer, but she was a rescue with a completely unknown past. We rescued her with a horrible compound comminuted fracture, and that alone might have increased her chances of developing bone cancer. I’ve never had an unsprayed female that had mammary tumors, cystic ovaries, pyometria, etc., though I’ve seen more than my share of all of those in other people’s dogs.
