One entry to update multiple records

One entry to update multiple records

Hi .. I am setting up a database for a dog rescue.  I have a list of dogs and a list of foster carers.  I have a field in the dog form to assign a foster carer to that dog.  Is there a way to automatically update the foster carer records to show the dogs name in their records.

At the moment I have to go into each record individually to update them.
