He’s a 2 year old Australian cattle dog mix. He’s bitten 2 people. He’s always been reactive/fearful since I adopted him at 15 weeks. The first bite I didn’t think he would actually ever bite someone. The second one was a mistake on my boy friends moms part (she opened the door for a nieghbor - someone my dog didn’t know). She needed 7 stitches. He’s 30lbs. I’ve always avoided punishment/aversive training because I didn’t want to punish out his warning signals (growling and barking) but there was no warnings during his last bite. He just lunged and went for it. I’m willing to go to a new trainer in my area that uses a prong collar/e collar (upstate canine academy in NY). My question is, is it worth going to this trainer or should I just BE? I would love to rehome him but I think I get the impression I shouldn’t with a bite history. I’m down to spend the money to try to get him better or am I just wasting money? I love him so much he’s my first dog ever but I love to be outdoors, travel, hang out with family and friends and I can’t because of him (I’m 25F) I’m so scared next bite will be a child.
