Your Russell Terrier is definitely not alone in having endless energy. They are known for being incredibly active and require a lot of exercise. My pup can run around for hours and still want to play more. It's essential to keep them mentally stimulated too, as they can get bored easily.

Oh, totally! Mine has boundless energy too. They're just made to run and play all day.

I relate so much to your experience! My Russell Terrier is like a little dynamo, always ready to chase a ball or dig in the yard. They have an admirable determination, which can sometimes lead them to get into trouble if they're not supervised. Regular exercise and engaging toys work wonders for channeling that energy, or you might find them bouncing off the walls.
