Newfoundland dogs are known for their instincts at water rescue. Consie and I swim with our dogs in summer. When I was doing my PhD research, Kaloosit and I would take a break on a hot summer's day and skinny dip in the clear, cold lakes of the UP. I would tread water on my back with my toes sticking out of the water and Kaloosit would swim around me. Our dogs can swim long distances or play fetch all afternoon. Yet, when they know it is time not to swim (before breakfast on a canoe camping trip) they know it is time not to swim.
