Yorkie And Jack Russel Mix 9 Months Old.
(Sanford, Florida, USA)
We have a cute little female puppy that we got at 8 months she is a rescue dog. She is training quite well except for one thing and that is out of a clear blue sky she will bite my wife.
One instance was I was sitting on the couch with the puppy when my wife walks up to hand me 2 phones, one in each hand when for no apparent reason the pup jumps up and bites her on the arm.
The Pup has nipped at her before, but not so much in an aggressive way. The last time drew blood. Can't figure out why she did that.
What is this, and what must we do to stop this?
