What does your friend want from the boarding kennel owners, they should have insurance to cover any mishap in their kennels so they will I hope have talked to your friend and asked what she would accept as compensation, if not then I would suggest writing to the kennel owners asking for an amount and if nothing is forthcoming then send a solicitors letter. I would be interested to know what the kennel owners say about the incident and how it happened, all the details are very important and getting that in writing is imperative.
