Sapphire, the Beagle, came to stay with us when she was 2 years old. She had separation anxiety, thus resulting in destructive behaviour.
One and a half years later, with training, positive reinforcement and lots of love, I can say now we all live in peace (it was pretty much h*** earlier) together!
She's a true comedian, keeps you from being a couch potato- in my case, being glued to the computer; I hope in the near future I will be able to foster Beagles and other dogs who need temporary homes.
