Yesterday Moss grabbed Eva by her throat and shook her, didnt mark her but her fur was wet, all she was doing was running next to him. Today Ollie was playing with his toy and Moss went to get it, Ollie curled his lip next minuete they were pulling fur out of each other. Moss isnt normal atall recently he was always a good boy, he has been chewing, he chewed the leather sofa!! he's scenting in the house. He's 14 months old and Ollies top dog i am keeping them seperate as i know Ollie doesnt take much crap from other dogs. Would neutering Moss help?? Im stuck at what the hell to do this is all in the last week.

Hi it might be a good idea to take him along to the vet and get him checked out, he maybe in some discomfort so thats why there's a personality change.  In the long run if he isn't getting any better it might be a good idea to get him castrated but it doesn't always stop them from being aggressive.

Warm regards Susan
