Yep, Bella is!!!
We spayed blossom at 7 months, and before she went into heat, and we had Dozer neutered a week later. I wasn't breeding either one of them, and there are many health benefits to them being fixed, plus they are siblings and litter mates, so had to do it because I wouldn't be able to keep them separated when Blossom went into heat. We wouldn't want puppies with tails growing out of their foreheads. Lol
