I'm wondering if anyone here has been bitten by their dog, seemingly unprovoked. My 2 year old GSD has gone into a rage twice. The first time I was putting salve on his sore elbow. The last time was yesterday around 3 other dogs that he only sees ocassionally. It starts with a deep growl and then he lunges at my arms, biting me repeatedly. He acts like he's in a frenzy when it happens. Shortly afterward he is fine, like nothing happened. He only attacks me. The rest of the time he's a wonderful dog, very loving and obedient. I have pictures of my arms, showing the damage, but wasn't sure if I could post them here, since they're a bit graphic. Any help or suggestions are greatly appreciated. Also, he is getting neutered tomorrow. We're hoping that helps.
