A few weeks ago my sister’s next door neighbor had a pittbull run into his yard and attack their kid’s pet goat Ivey. He ran out and shot it but it had savaged poor Ivey beyond help so he had to shoot her too. What a mess!! The dog had a tag so he is going to look into suing the owners if they can find them. The poor little boy witnessed the whole thing.
Most states have dog/livestock laws so it shouldn’t be a problem to recoup the momentary loss but the emotional loss is another thing.
She could also check “animal trespass laws” for her state.
Ours covers everything from cats to cows.
Depending if the tag is a rabies tag, it can be traced through the county’s records.
