Before taking your pet into a pet sitter, you need to be sure that they will have the right care and the right overall health. Have your vet give them a vaccine that will help to protect them from other forms of illness such as bacterial or fungal problems.
Learn all that you can about the pet sitter that you use. If you will be using a pet boarding facility, find out if they are part of the American Boarding Kennels Association, a group that provides guidance and care to pet owners in this situation.
