Thanks alot BostonRot! I trust what my vet says but because I'd never heard about this I just wanted a 2nd opinion. DH and I discussed it again last night and have decided not to neuter Oscar. We may re-visit it when he's older (4-5 y/o) but only if we deem it necessary. My dh never had any behaviorial reprecussions from not fixing his last male Rotti.
Thanks again, appreciate your response/ insight.
