I am after some advice re neutering. Leo who is 6 years next month has never been neutered. I have never felt the need. He is not a dominant dog, doesnt mark his teritory, does "hump" and has NO agression issues until now.
When we were on holiday last month we met a family with three cavaliers whilst out. Leo was all waggy tails when he greeted the two females but growled and barked at the male in quite an agressive way. I put it down to a clash of personalities as he's never done it before.
Then today we were at my brothers, his neighbour has a lovely cavalier boy, when she introduced him Leo went for him!!!! He was growling and snapping, ive never seen him like it before.
So my question is would having him neutered calm him dow. he's usually so dog friendly but I dont want him going for every male dog we meet. I know he's only done it twice but thats twice too many.
Any advice would be great.
