PD suddenly VERY aggressive, help!!
Hello! I am completely new here and unfortunately entering on a negative point. But I need HELP asap!
I got my little PD in mid June when he was about 8 weeks old. He adapted quite quickly and never really displayed any sign of aggression other than some playful biting.
He even stopped that playful biting for quite awhile. For the most part, he spent all of August cuddling, sleeping and being a perfectly sweet little boy. The only time he'd get nippy is when he didn't get his way (ie- us handling him when he didn't want to be held, my dog stealing his carrot, etc.)
Today, he viciously attacked my brother. Eric has all of these cuts all over his arms from Goliath biting him and clawing him. These were DEFINITELY not playful bites. He would not let go. He chased Eric around the house, made this...rattlesnake noise. It sounded like a cat purring, only def. not the same connotations. He puffed up and just went at him. My brother even tried shaking him off and couldn't loosen his bite. His hand and arm were bloody and bitten and I feel so bad. Eric lives with me, so he is certainly no stranger to Goliath. We have no idea why Goliath lashed out on him like that. I suppose he could be intimidating- Eric is quite a big guy and has a loud voice- but then again, in the couple months weve had him, this has never bothered Goliath before.
Later on, I was petting Goliath on my bed and I called Eric in, hoping they could make some kind of amends. Stupid idea. Goliath was practically asleep until he saw Eric and IMMEDIATELY jumped up, puffed up and LUNGED toward Eric in complete attack mode. Eric jumped away from onto the bed and Goliath kept coming after him. We kept blocking him from climbing on the bed with a pillow and but he was RELENTLESS. He finally got Erics foot. Then he went after my sisters foot- and my sister is his primary owner, too. He sleeps in her or my bed with one of us at night. His cage is in her room. She feeds him, etc. And he would have kept attacking her had she not jumped on her desk! I'm not sure if he would have attacked me- I covered my feet with a pillow (and was wearing jeans). But, I was honestly afraid. The only one Goliath didn't go after was my pug!
After he calmed down, a little while later, I came back, gave him a Cheerio and pet him. He seemed ok. Then out of nowhere, he bit my hand. It wasn't as vicious as before but certainly not playful.
I have no idea whats happened. Has he lost his trust for us? Can we get it back? HOW can I have the little sweetheart back and rid the house of this little terror?
The only change thats happened is that up until about a week ago, he roamed the entire house for the better part of his day (with supervision). Now, hes been confined mostly to 1 bedroom (the one with his cage). And like its been from the beginning, hes out of his cage for like 80% of the time. Regardless, he can't go back to running around the entire house because we live with my dad who can't tolerate the turds (though we do let him run free whenever my dad isn't home).
Helppppp! and thank you in advance!!
