Leave treats outside your door when people are coming over and when they come in the house have them offer her a yummy treat and/or a toy. That way when she see’s people at your house she associates them w/ good stuff. Raisin can be fearful of people and shy so I have them offer him treats and squat down to talk to him. No bending over him and petting his head. I say here offer him a treat, let him sniff you and then pet his chest all at eye level. It seems to work well for him.
