The humane society didn't/wouldn't tell us, the only thing they let us know was why she was turned in originally, which was behavior problems. Digging, chewing, trash picking.........the usual for an 8-9 month old puppy that isn't shown any better.
It would not surprise me at all to find out she had been returned, when I say chew & dig............I mean CHEW & DIG.
Edited to add I am talking of Phoebe (border mix)
