our dog is getting very dominating he has already bitten myself and my partner drawing blood, I took some food off him the other day that he had got out of the bin and he went for me again snarling at me , but the worst is when my boyfriend kids come round cause the dog wont leave them alone the dog snarles at them and circles round them jumping at them and barking . Am i over reacting about this dog??, will he stop this behaviour??, im not keen on keeping him but my boyfriend wants to, although my boyfriend is at work alot and doesnt see how bad thye dog is. im at the end of my tether with the dog please help.
