I have been lurking in "bad dogs" for a few days now, trying to find a similar post and I just don't. Not sure what to say I am a big mess right now. On Saturday, I had to run out and get some things for my sisters Birthday dinner. Theo is not left alone because of his seizures and I usually crate him when I go out and my sister comes over to keep an eye on him. For some reason, I thought he'd be happy in his stroller this time, what a mistake that was. Theo is always vocal when I go out, he barks and barks and the minute I shut the door he stops and is always a sweetheart for my sister. I've never had issues with either of them, except for a bit of barking. Well on Saturday when I put Theo in his stroller, he barked at me, but then tried to lunge at me!! I was really like WTF is he doing! He didn't stop thought, he lunged and lunged and got so aggressive I rolled the stroller into my room and was thinking to shut the door and let him cool off. Well once in the room, he tried to lunge at me again, and was so aggressive towards me, I was scared. Really scared. This is not the dog I know. So he lunged again, and flipped the stroller, and came after me!! He has tried to grab onto my clothes before when leaving but this time he grabbed my arm and didn't let go. I was really freaked out and didn't know what to do. He kept grabbing and biting and I yelled at my sister to come and help me, she grabbed him and he let go and latched onto another part of my arm and started shaking my arm, my sister got him off, he grabbed and bit my leg, he was fine with my sister did not try to bite her at all. I even took my other hand and tried to pry his teeth off my arm, and so he bit my other hand. I am freaking out writing this here and actually telling someone other than my sister who was here. I feel sick and I haven't been "ok" since Saturday. My sister finally got him in the crate and I left the room and went to the bathroom to see what he had done. I can not believe the damage he did. My arm has deep bite marks all over it, and my leg was already purple. I sat on the damn floor and cried for a long time. My sister told me to go to the hospital and I didn't because I didn't know what they would do to Theo. He has never shown this aggression other than barking. So I wrapped my wounds and called my vet and brought him there. The only thing I could think of was that there was something medical going on. He was checked from a to z and vet found nothing wrong. He is still weak in his hind legs but that he normal as he just did 8 weeks crate rest because of his back. I don't know what to do. I brought Theo home and went right away to a professional animal behaviorist up the street. They are really good there and they told me to stop babying Theo and start showing him I am the boss. Well, yup he has been babied for a 8 weeks now cause of his crate rest maybe that had something to do with it, I don't know. I've gone through so much with this dog as you all know, all his medical issues, he always comes first, and now he has done this and I don't know what to do. I can get him 6 lessons with the specialist which they say will work, but it costs 500$ and really I just don't have that right now. I am struggling enough, with him going down and the vet bills and neurologists, it has eaten all my savings. I am at a loss here. I can't think and I don't know what to do. I though maybe my Doxie family could give me some advice on this one. Someone told me to put him down, and I was like WTF are you nuts??? Its not an option, he is not a bad dog. He did a really bad thing, but he is not a bad dog. I don't know what to do.
