We went to the vet yesterday and I am happy to report Booth is doing very well! No signs of parasites, so he much have been a picky eater on his adventure. He did pick up a few ticks and we will be monitoring him for tick borne illnesses over the next few months.
We got the microchip and the little guy didn't even flinch!
Booth went on his first walk with DogCentric walker, Jessi, Monday. She reported that he did a great job! Jessi walked him with two leashes for good measure, and it appears he is not interested in running anymore.
