hi varkhond, thats why i didnt bother too much with the first incident, cos my 5 yr old did stick her fingers thru the fence, luckily i grabbed her away , she suffered only a scratch, i am a massive dog / animal lover and have a gorgeous black lab who has never put a paw out of place, and i know my love for my doggy and i have great compassion with the ownders of this other dog, as they say he is a great family pet but very protective, there is no warning with this dog - no growling or barking he just bites
