He got the dog almost a year ago as a 5 month old. It had been thrown at a wall by it's owners partner. The owner had the sense to take it to a vet and the owners Mum then asked DB if he would have it.
She's a nice dog in many ways...half greyhound and half something else but she is very badly behaved when visitors come. Yesterday my Mum went to see my bro and the dog was well behaved for once until Mum was leaving....she went out the gate and Db and the dog were in the yard waving...the dog got all jumpy and then bit my brother on the arm...one puncture wound.
She's generally snappy and leaps up at people....he puts her out of the room when she does this jumping up and "play snapping" type thing. She does it more when children come...my DC are scared of the dog due to her leaping ON to them when they sit down.
Brother puts her in the vestibule with the door shut and tells her no when this happens...he always does it straight away. He has treats in his pocket to reinforce good behaviour like sitting and not running away....but she's a little rotter at times and he's upset she bit him and nervous incase she bites soemone else.
She is dominating a lot...when Mum arrives, the dog will try to leap into the passenger seat if Mum is giving my bro a lift somwhwere even tho the dog knows this is my brothers seat!
She is very attention seeking. She has three walks a day.
he REALLY loves her...she's been great company for him as he's had a hard divorce recently and has been lonely.
What can he do?
