Buddy is/was my brothers dog I think he is a Jack Russell x Red heeler but not 100% sure. He is currently living at my parents house where I also live with my 2 kids.
My brother wasn't the best owner and often hit Buddy to correct his behaviour.
He moved in with his gf who didnt want Buddy there at all and when my brother was out said the dog bit her son unprovoked. I know the kid and he is a little ****. I've seen him drag their the cats around by their paws/tails & really isnt animal friendly.
So Buddy was dumped on us. (If he bit the kid the responsible thing is obviously to give him to a home with 2 kids?)
He is a very loving and affectionate dog but as soon as voices are raised or the kids get really loud and run around he changes.. He becomes very scared/timid and goes and hides.
Things really took a turn for the worst about 2 months ago. The dogs go on the front verandah when everyone goes out (this is rare someone isn't home)
I was leaving and had the kids on the verandah & called out to the dogs. Kimba ran out no dramas but Buddy ran from the lounge to under the parents Bed. I went in and called him and put my hand under towards him to tap the ground near him (in hindsight a bad idea) and he lunged out and bit me. He drew blood on my hand. He knew straight away he had done the wrong thing and ran out into the kids play room and hid under the table.
I went out and as soon as I stepped in the room he growled. I went closer but he started snapping and was being incredibly aggressive so I left him.
My parents got home and he was a totally different dog.. really happy and as if nothing happened...
Since then he hasnt been allowed unsupervised near the kids and TBH I wanted him either gone or PTS. If he had bit the kids I would have taken him in without hesitation. My parents just blamed me for the whole thing.
Tonight Lily was at the table eating and he was underneath just lying down. She swung her legs out (she does on any chair when she can't touch the ground) and nearly kicked him & he started growling. She got up and kinda jumped along towards my dad to give him her bowl. Buddy came out from under and was trying to bite her.
I yelled out and he froze, stared at me then I yelled "out" and opened the door he cowered under my dad trying to hide. I called his name and he peed everywhere.
Dad just told me to shut the door and leave him alone. I've taken the kids downstairs with me and am packing our bags for the weekend to get away from it all.
I'm at my wits end with this dog and my parents. I don't want the dog to attack my kids for them to realise he is a threat. He bit me hard enough to draw blood, imagine what he could have done to a kids face...
I don't know what to do. Since he has been here we haven't hit him once. I have trained him and we've given him nothing but love and affection but he still has all these issues.
He also is getting increasingly aggressive to other dogs. My dad only walks him when other dogs are not out..
Any advice etc? Is there anything I can do to change his (or my) behaviour?
