About 10 days ago i lost my other dog Lucibelle to coyotes--Neeka was fighting them but came out unhurt, thankfully. Since then she has been very aggressive with my fathers 6 month old golden. She has also showed aggression towards me--i tried to reach into her crate to take a bone out that she had taken from jack and she growled and snapped at me. She also has been having aggressive nightmares--when she is sleeping if i move she will growl and snap until she realises its me. i have moved her crate into my room and she will sleep in it but is guarding it from everyone. Also, lucibelles crate is in the garage--if she gets into the garage she will guard lucys stuff or the dog food we keep in the garage. Now the problem is everything i have read has said not to disipline her because she is suffering from being tramatized. she also has been puking alot of clear liquid when she gets all worked up and aggressive...any suggestions on how to get her to stop while not disiplining her?
