This was expected, and good for him and future dogs.

He'll be a little lonely, but they need to check to know about his viral load/shedding.

Bentley had a very comfortable evening in his temporary housing snuggled up with all of the wonderful toys and supplies you have all provided - Thank you! This morning the Texas A&M Emergency Response Veterinary Team dawned their suits under the watchful eye of our own Dr. Cate McManus, and headed in to begin Bentleys daily care ritual, which he has become very comfortable with. He is such a good boy and is quickly adapting to the routine! Bentley is still resting comfortably in his crate in-between his care routine visits.
We wanted to let everyone know that
we will shortly move into the next phase of Bentley's quarantine. This temporary phase will include moving Bentley to a special kennel that will help us collect his urine and bowel movements for monitoring and testing . This is the least invasive, safest and most comfortable way to complete this process for Bentley, and for everyone involved. This phase isn't expected to last more than a day or so, and as soon as this phase ends, Bentley will be returned to his current set up and care routine.
Stay tuned for the morning pics once the family has given us permission to release them. Remember, we have put this process in
place to ensure that Nina has first glimpse at her number one cheerleader.
