Were do seeds for a seedless watermelon come from?

I understand that dogs can't eat watermelon seeds, can they eat the white ones?

• I removed all the black seeds but it was really irritating to remove the white seeds. I was wondering if dogs can eat them. For the record, I only feed my dog (from the table) seedless watermelon, bananas, and apples without the seeds. Aside from that, she eats her dog food.

• Answer:

  i don't seed the watermellon instead I jsut by seedless and the white ones are not real seeds yet. apple seeds though have poison in them and are toxic so keep coring the apple. carrots and squash are also great snacks.
