(not puppies as a con as i am able to secure her during her seasons),
That's what you think but sometimes their desire for an evening of fun is stronger than your containment, I've heard so many stories of people that end up with a litter because their pet escaped. But PLEASE spay your dog, it's well worth it. By getting them spayed it eliminates the chance of ovarian cancer and decreases the chance of mammary cancer.. so in the long run saving your dog from lots of pain, and saving you money. Your dog will be so much healthier if you get her spayed. Pets don't actually get fatter if you spay them, the reason why people think this is because usually people who spay their pets have their pets living the indoor life of luxury so of course they are going to be heavier then the stray dog who has to fend for herself that is unspayed. But please please please for your dog (who sounds like a beauty, and I would love to see pics) get her spayed.
