Just found this forum! I'm another ex-pat now living in Australia, up the coast a bit from Sydney.
We have a beautiful White Boxer, Azura, as well as a Mastiff X, Athena, and a male Bull Arab type, Buster, who is deaf and partially blind.
Azura is 6 and was a rescue, had been abused and starved.
Athena we've had since she was about 6 weeks old, she's 3 now.
Buster is a recent addition, a foster failure, and another abuse victim, and he's approximately 10-12 months old.
