dogs strange behaviour

is there any animal specialists out there ? since my ex left ive noticed a big change in my dogs behaviour, if i have friends family round she will not let me speak to them she ll look at me bark and growl over my talking, this afternoon i had 3 friends over, she done the same barked and growled every time i tried to speak it got to the point i had to put her in the garden, 2 of my friends left so me and the other friend sat on the sofa chatting, the dog stood in front of me barked, growled this time no tale wagging and barring her teeth at me, shes never done this before and ill be honest it actually scared me and my friend. after my friend left she returned to her normal happy dog behaviour, shes a 6 year old boxer, i dont wont to get rid of her ,and she was never like this before he left. any ideas ?

I''m convinced that dogs pick up on our anxieties so maybe she senses that you feel frightened and is trying to protect you. I''m no animal behaviour expert but would suggest keeping her to her normal routine as much as possible. My dog has benefitted from the marriage break down because I walk for miles and miles trying to clear my head. Would you say that the dog is your dog or the STBX''s dog? I suppose there might be an element of re-defining who''s ''top dog'' in the family pack. Might be worth a chat with your vet if it continues.

Did you discipline the dog if it was needed or was this left to your ex? Dog may now think it''s alpha - let it know its place

Whatever is causing the behaviour dogs need to know who is in charge. We had a red setter, well two actually, and one wouldn''t let my ex come to bed. I would go to bed and invariably just after I''d fallen sleep I was woken up by my ex jumping around and cursing at me because the dog wouldn''t let him past. The dog just needed to be firmly told to stop and he was fine.

thank you for that its all made sense to me, she was far more the exs dog she used to follow him every where, and yes he was the one to tell her off. retraining will start today. thank you xxx

Hope this goes well, my stbx is going for custody of the dog which isn''t even his it was bought for my daughter who is currently at university before i even met him, she is going mad and has said that if he tries to take her she will kill him! How can someone take a childs dog????

thats a wicked thing to do, theyve got no morals.
