Fear Period...13.5 Weeks of Age..

I've noticed the start of some fearful behavior over the last day or so. This morning Trigger was very apprehensive of the pooper scooper and also started barking when he heard the garbage truck pull in front of the house. He's also afraid of his collar and dislikes having it fitted around his neck.
I decided that it is time to ramp up his outside world experiences. He's had 3 set of puppy vaccinations and so it is time to take more chances with the outside world. His first puppy class is tonight but I decided to take him over to Stanford campus this morning. Stanford has lots of lawns, bikes, people, cars, buses, trucks, squirrels, trees as well as being quite dog friendly.
The car ride went pretty well up until he decided he needed to urinate on his crate pad. But, at least there was no fear, vomiting or drooling happening. Randy suggested just removing his crate pad and seeing if that makes the crate a less attractive peeing venue.
At first Trigger was OK with walking along the sidewalk but soon became scared and refused to budge. I was able to pick him up and carry him over to a bench where he sat on my lap and watched all the commotion around him. At first he was trembling but after about 30 minutes he was sitting next to me happily with his ears up watching the world around him. He was quite interested in a Bedlington terrier that walked past us with his master. (I wonder if he thought it was a baby ewe?) He eventually forgot about being scared and we set off for a walk around the campus. He was fine on the leash except for barking and showing some fear towards one heavyset man who walked by us rather grimly.
His car ride home was blessedly uneventful. And I'm happy to say that the pooper scooper was no longer a scary proposition after his outing.
He's had a bath, a play session with Gladys, a meal and now he's down for a nap. We'll see how puppy class goes tonight.
