Four months old today! He did great on the 2 and 1/2 hour drive home with a potty break or two in there.
He's been introduced to the 3 cats--not really all that interested thankfully. Also had a very noisy introduction to the corgi and the brittany. Through a gate initially, then one at a time together, then all 3 together. Other than the two old dogs crowding him a bit, they did quite well together.
