Perils of trusting your pet to invisible fencing
For those people that use or have considered using invisible electronic fence for their dogs - look at these pictures of a tiny Jack Russell Terrier that was attacked by big dogs in her own yard!!!!
A total of 7 dogs were fighting....poor little Molly got the worst of it. The dogs had her down. A rescuer beat off the dogs using a doubled up heavy chain leash. Molly was shivering and going into shock.....

Wound on chest

At least 4 wounds on back of neck....

Gaping wound about 3 1/2" long and at least 1" deep on left shoulder
