At a Texas State Park yesterday, an unleashed dog attacked our leashed dog. We did not stay & talk to the man since he had another unleashed dog nearby. At home that day we saw our dog was bleeding - she had minor surgery & needs follow up. We made report w/park police & put the vet bill & our ph/add on the man's truck since he was in bed. We called him today & asked what he wanted to do. He said we could've handled it earlier & hung up. PLEASE HELP!
