Hi I've got a spaniel cross he's 3 and we had him from a pup. He's become aggressive over the past year. It seems like for no reason he can just turn and be aggressive towards me and my son. My husband left for OW 6 months ago so I'm on my own and can't afford training. I'm just scared he's going to bite as it's just so unexpected When he starts to growl and snarl . I'm torn between getting rid of trying other things but at the min we are scared of our pet!
