Some dogs may have a comma in the name as an abreviation like " Mike's " or " Calron's " and when searching for these dogs you can do it a couple of ways to make sure you dont miss their records.

 

Try searching for the name without the ' or with it to see whether it comes up or not.

 

Depending on who added the record to the database a comma may not have been added and the database would see the record differently.
