Thanks for all the responses. I will definetely try the bread idea! We adopted Stanley when he was almost a year old. He's 2 1/2 now. I've been trying to slowly socialize him, but he gets so stressed out he just shuts down. I do try to walk him daily, but usually only in the evening because he's small & cute so people tend to "rush" him when they see him. I personally alway ask if it's OK before petting a strange dog, but many people don't. I've had several bad experiences where he was really freaked out by strangers reaching for him before I could stop them.
I feel like I've made lots of progress getting him used to being in new places (with no people around), but it's time to start going to populated places (slowly of course). My vet recommended using a natural calming remedy to make it less stressful & scary for him. The only one I know of is Rescue Remedy, but I really don't like the liquid form. I plan on trying the bread idea, but would still be interested in hearing of anyones experiences with other products.
