Lisac...I was going to post about swimming then saw yours. We have a 5 month old mini doodle. It was warm here in NJ for a few days like a week ago. We always hike at this park and took Dunkin on a warm day. He was watching bigger dogs fetch sticks and balls out of the lake and wasn't too interested in the water. Then all of a sudden he took off after a lab and jumped in the water and started to swim out to fetch the other dogs stick. My husband and I got so worried that my husband was ready to jump in after him. Turns out Dunkin knew how to swim and enjoyed fetching his own sticks in the water. Who knew he could swim?!?!? So my question is...is he too young to be swimming with the big dogs?
