Me and my boyfriend adopted a 5 year old Lurcher cross about 2 months ago. From the beginning he has been vicious, biting my friend and my partner on more than two occasions....although the first two times we believe were due to a lack of thought on the humans side the dog seems to have come between me and my partner. Where my partner seems to put up with all the dogs bad behaviour ie biting etc it really scares me to think how far he will let the dog go before getting rid. Don't get me wrong I absolutley adore dogs but this one is just a plain nasty animal and there would be no love lost if he were to walk out of the door. Just wondered if anyone had any experience with aggressive dogs.....all comments welcome
