Why don't you ask him to pay for your dogs to be Boarded for the 3 days you are gone. His workers will be safer, your dogs will be safer, and everyone gets what they want. That Was Easy.....
I represent Employers, but I can recommend Worker Attorneys in So Cal if you ask.
You could also ask the developer to put up a temporary fence in your yard until the new fence is completed. If he refuses, you could have it done yourself. It is not that costly and overall might be about equal to the cost of boarding your dogs.
There is probably nothing you can do legally to stop the developer short of getting a restraining order. It would be far easier - and cheaper - to board the dogs or put up a temporary fence.
Mr. Corson has suggested the only practical resolution I can think of. The other alternative would be to post security on the property who could call the police in regard to potential improvements of personal property and trespass or you could go to court and get an emergency restraining order prohibiting any action while you are gone. Either one of those alternatives would probably be impossibly expensive. Seriously consider Mr. Corson’s suggestion.
