Miikkas Mom - thank you for that link. Very informative and I shared with my husband. Having lost a female mix to hemangiosarcoma which was so awful, seeing the stats for that increase for neuter/spayed dogs really concerns me. *IFI we neuter our Rolf, we'll be waiting, hopefully until he's 2. He's just 8 months now and at this point, we don't really see a reason to do it.
