Maybe try a trainer. Riley was nuetered at 6 months and was reactive to other dogs. We were working on it before he passed at 9 months. Once he was around the same dogs for a while he was ok.
In Kaleb's contract it says not to neuter before 18 months. The breeder says they need their hormones to grow and mature.

He will always be in my heart.
