a quote from Tim a while back...
TO B HONEST ONE OF THE REASONS I BOUGHT HER IS BECAUSE I WORK 3rd SHIFT IN THE COAL MINES, AND FOR SOME REASON PEOPLE R SCARED TO DEATH OF BOXERS AROUND HERE ANYWAY.
I'd suggest rehoming her. Then instead of ever getting another dog, install an alarm system and buy a gun (careful with the kids) and your family will be safe when you are at work. You could have done that with the money you 'wasted' on Daisy. My heart goes out to Daisy.
