Positive reinforcement is the key. We have a choc lab that was a handful and did about 12 lessons with her, 80% of the training was the owner.

My suggestion would be to stock up on hot dogs and string cheese. Whenever a visitor is to arrive get some small bits of hot dog and string cheese ready. Planning may be necessary, meeting in the drive out front.

Have your friends give your dog the treats when they arrive so your dog begins to associate strangers walking in with a happy thing. People Food!!

Always have them hold the treat to their mouth so the dog makes eye contact then feed the dog straight down from the face so the dog looks at them, this is important, once the dog begins to make eye contact it will begin to trust and this is where you want your dog to look at you always anyway.

I would start with this maybe reinforcing this positive action over and over while the guest is there.

I keep beggin strips and dog biscuits in my work truck, I am a Land Surveyor and I have to go in your backyards. Over the last 20 years it is a rare dog I cannot win over with treats.
