More: Sparky is curious, friendly and outgoing. True to his Bernese Mountain dog genes, he loves cold weather and rolling around in the snow. He's also the best family hiking companion and a great climber. From October to March, dogs are able to be off leash at our local beaches, where Sparky enjoys beach running and exploring. This is where this photo was taken. This sweetheart is a joyful addition to our family outdoor adventures!
