Last Sunday a 9 yr old girl who is a friend of my daughter was walking her neighbors dog. Both are mutts from local shelter . We have had our female since she was 1 month old. My dog was in our gated backyard. The other dog wasw in the front yard. my daughter, the girl walking the dog and another 9 year old girl decided that they wanted Mel our dog to play with other dog. Mel has never been in a fight with another dog. Girls opened the gate they were infront of the gate. the gate is in an cramped small area. The other dog was leashed. The dogs both lunged at each other the encounter lasted appox 15 seconds. My dog was fine other dog seemed fine too. Girl took dog home. Other owner found puncture by ear. She took her dog to an emergency vet. $800 later. ..We offered to pay one half of the total cost. she is insisting that we pay the entire amount. Does she have any responsibility? What is your take on this. Numerous phone calls of her yelling at me. PLEASE RESPOND ASAP
