A Hamilton woman has been taken to Waikato Hospital in a serious condition after being attacked by her dog this afternoon.
The woman is in Waikato Hospital after being bitten on the face and neck by the bull mastiff-cross at a property in Avalon Drive just before 3pm.
A Hamilton City Council spokesperson said the dog was about six years old and the woman had owned it since it was a puppy.
It was known to authorities because of an earlier incident with another dog, which earned it a "menacing" classification.
However, there had been no other reports about the dog since then, the spokeswoman said.
