i have a boxer named zeus which is 1 yr and a couple of months old and also a german shephard who is the same age. Zeus got attacked by a Husky when he was 8 months old at a dog park in the parking lot and ever since then he hasnt been the same. if he sees another dog other than Dante (german shephard) he goes ballistic. he will stare and growl because he still remembers that day. Today i took them to a park near my house and while i was walking them on by the pond Zeus had seen a duck and tried to go after it but i had him on a leash so he didnt get to far. since he couldnt get the duck he turned around and lunged at Dante. And they got into a scruffle. This is not the first time though. Neither one of them are neutered. And Zeus gets jealous if i pet Dante and starts to get upset. I was wondering if i got Zeus neutered would it calm down his testosterone enough to where he wont act like this. Please let me know. Thanks
