I have a male jack russell, we’ve had him since a pup he’s now 10 years old. The problems we have is his aggression it used to be only towards my partner but now myself and daughter are at risk, it’s got to the stage I can’t even walk him as he will want to attack me if I go near him to attach lead, I can’t even get close enough to put muzzle on him he’s very stubborn, when he attacks most of the time there’s no warning it’s 0-10 straight away, it’s like he blacks out and savagely attacks bitting several times before snapping out of it, the reasons for attacking have been just because my partner picks up his phone he goes for him, or he will suddenly just start growling aggressively then the moment any one makes the slightest movement he attacks, I’ve got to the stage of being so fearful of him at the same time so stressed at the thought of how can I help him if he needs a vet if I can’t even muzzle or put a lead on. He’s not been himself last couple of days I think he might be in a bit of discomfort from his back legs as he’s not jumping on sofa so well, but I don’t know what to do or how to get him help with his behaviour his attacks are not little, we have a lot of scars on arms,hands and legs he leaves deep wounds and injuries I’m scared to put that on anyone else please help. I would like to add that I’ve tried training, he can be obedient when it comes to giving certain commands like to get down off sofa or bed he will do it or when I say stay or sit he will also do it he won’t try escape or run away, it’s the unpredictable aggression and the fact I can’t harness or leash or wouldn’t dare be able to pick him up anymore like I used too. He will need a vet if he gets any worse but how can I get him to a vet for help!!!
