As for flunking puppy class, he was just to young for structured classes.
Some dogs stay at the puppy stage longer than others. I would have waited
till 6 mos and tried it again. Glad you got a refund on class fees.

Have you ever put on a raincoat and walked Nobas in the rain? Not pouring
buckets or anything, just normal rain. I often wonder what those living in apartment buildings do when their dogs need to be outside for awhile.
