Betty is my brothers second Boxer. So Murphy’s sister.
She is a little younger than Murphy. Being useless, I’m not sure exactly how much but around a year or less.
The two are completely inseparable. When Betty’s not sooking up to the nearest person she’s cuddling or alternatively attacking Murphy. When she’s not doing those things you need to worry because she’s likely thieving something edible from steaks to rubbish.
