This is after he went through a mud puddle:
And here he is in the car on the drive home, I picked up a stick for him to play with on the ride home:
He is so funny in that dog park, he'll run way ahead of us then either stop and wait for us or come sprinting back to us just to run ahead of us again. Once along the river he had lost us and went to a few other couples sniffing them and we could tell he was getting confused and scared but we had our eye on him the whole time then we both yelled "Harpo, Harpo come here" and I have seriously never seen him run so fast in his life! He came dashing back to us and literally ran into me, it was pretty funny.
