I am 25 year old female that has had onyx since he was a puppy. He has been treated as my child since.. due to homing circumstances we have been in an extremely high stressed home environment for the last going in year .. and I'm expecting a new baby.. onyx behavior has declined badly..he did have obidence training as a pup.. recently he has bitten a child he's been around his entire life.. shows aggressive to unknown dogs.. fine with the one he lives with. And is extremely timid and anxious due to living with my father .. who seems to be the only human he sincerely doesn't like.. he loves everyone else .. and is really a loving dog.. I had him evaluated by a professional behaviorlist and was told he is extremely stressed... due to always being confined to a room etc ( he barks at my dad so he's not allowed out ) .and not feeling included at home . he also mentioned that he will be ideal with a move to a non stressful environment.. due to the child biting and increased level of aggression I can't manage him anymore or risk him hurting my new baby .. I love him so much! He has celebrated every birthday he's ever had . Really praying someone can help rehilbiltate him and love him for ever. Please contact me !!!
