There's been a fair bit of this happening recently...there seems to be a foster-failure epidemic! Having had Huskies before, Cathy and her family initially applied to adopt a female Husky, but fate had other plans. When the girl they were interested in found a home elsewhere, they volunteered to foster until the right dog for them came along. Turns out that their first foster dog WAS the right dog...and he happened to be a Malamute boy instead!
So congrats to Cath, Michael and their children (and Lolly the Labradoodle!) on officially welcoming Oso to their family.
