i think about it, but then i think how amazing it would be after i lose her to have one of her puppies.
i recently lost my sheltie,
she had given birth to a litter of 4 puppies (3 survived) about 5 months before her death.
i had given all her puppies away to good homes, like every other time.
When Grace died, i kicked myself for not keeping one of those puppies.
so you're right, it's a tough call.
i just can't wait forever, as i have an important spay or not spay decision in my head..
