The risks of breast cancer aren't an issue till the dog is 2 or older except in very rare situations *sigh* and neither does it complety remove the chance of it, just signifigantly reduces it. I hate that vets use "cancer!!!" as a way to scare pet owners into spay/neuter. I can't figure out if its a deliberate step on their part or if they are honestly unaware of the real % of risk. To be fair they DO get to see those cancer patients, and what they suffer through, and those dogs probly stick on their minds better than the healthy dogs, but still.....(its a peeve, can you tell?)
