Your dog will be walked to your specifications, normally between 45 mins to an hour on a route that you define.

The sitter will not let any dog in their care off the lead.  Although you may usually leave your dog off, they will not always respond the same to someone else as they do with you.

Only if the same sitter walks the dog long term, and with your permission would this be allowed.

If a sitter is to walk your dog/s whilst you are out, then an arrangement between yourselves and the sitter should be made regarding the keys to your property.
