So a little more than a week ago my mother-in-law, who lives in Texas, had two registered yorkies come on to her property and came to her fence while her dogs were out. She has an older male neutered pit mix and a beagle. Neither of the dogs have been in any altercations. The yorkies were a block away from there house running without leashes or owners in sight. The pit bull was able to nudge his way throughout the 6 ft wood privacy fence by breaking the gate. He bit one of the yorkies and from what the owner says broke two ribs and a leg. Today he came to my mother-in-law's house asking for split cost of the vet bill which is 600. He was very threating, falsely bringing up the fact that animal control can take action against the dog. Like I had spoke to my mother-in-law and coached her about, I told her to take some time about the matter, don't admit anything and she told the man she would decide what is best. She will have to pay to have her fence repaired. Looking for some impartial advice, that isn't to tell her to move. Thanks in advance.
