Oh boy...I have never heard of a "vicious" Jack Russell Terrier. The article does not mention the extent of the one-year old's injuries?
I just wonder if the parents of the child over reacted and now this dog has been deemed vicious? I know that Jack Russell's are known to be very intelligent dogs. I understand they can be very hyper too and they need lots of exercise and training.
This article really doesn't go into detail about the incident...but if the owner of the dog can get him back...then I am thinking that the injury was not that serious?
