Jack Russell x Border Collie. Have had her since she was 3mths old, took her on temporary for a friend and ended up keeping her.
Brought up with my DD & DS (aged 2 & 3yo) and been fine with them, up until 2wks ago.
2wks ago, she bit DS just under his eye, breaking the skin and it bled, not loads but enough to make me panic. He wasn't doing anything to her, just sat by her (she was sat by the front door, and DS next to her) and she snapped and bit him.
This morning, she bit DD (3.7yo). DD was cuddling the dog, she does this all the time and the dog has never reacted like this (well until this morning) dog snapped and bit DD on the cheek, not breaking the skin but leaving a nasty red mark/teeth line - I'd say that mark will be there a few days/week.
What the hell do I do? Why is the dog doing this all of a sudden? Does she need 'knocking down' in the pecking order or something (no idea how to do this if so)?
She is trained and generally well behaved, but she has bitten twice now and I'm worried.
When I tell her off she snarls at me, and snaps at me, I don't know why she's doing this but when she done it this morning I shouted "NO" at her and put her in the garden. This is what I did when she bit before.
What would you do?
