When I got Milly spayed, the vet recommended 6 months old, before the first heat, as a cancer preventative, but she did also warn me that spaying so young could also lead to incontinence.
I decided to go with before the first heat, but then at 6 months old, almost on the dot, Milly came into heat for the first time, so I had to put it back until after.
I think if you have her spayed at 6 months that's about the minimum age, but if you're unlucky, she might come into heat before the op. I don't think there's any way to tell for sure. |
