She 8 now and I could never bring myself to put her through the operation as it seemed from my perspective unnecessary and cruel. I feel very emotional about it as she can't tell me what she wants, I know probably weird. There is very little chance of pregnancy as no male dog has ever shown an interest, I'm guessing cos she was so small. Vets always advised to neuter to avoid womb cancer or initially lower the chance of breast cancer. Breast cancer not relevant anymoreas she's older. I have been advised pyometria is a high risk to older small dogs. AIBU not to get her neutered? I'm worried about risk of her having op and no one can provide me with statistics about incidence of Pyo in the general population, just anecdotal including vet. Thanks
