We first noticed it with Ivy. She loved laying in the stripes of sunshine that play out on our floor. Roxie is the same.
My initial inclination is to assume this is a ‘dogwide’ phenomena even though two examples is a little light for a scientific study. I’m sure you’ll let me know.
As I type Roxie is on her back on the rug in our foyer. Her snout and chest are in the shade. The area from her belly to her rear legs are in full sun.
Roxie’s coat is dark. She’s absorbing lots of heat from the strong August sun. In the abstract that would seem uncomfortable, but it’s her optimum choice.
She’s relatively motionless right now. In and of itself that’s unusual. As a teething puppy Roxie is usually in motion playing with her toys or biting at something or someone. It’s nice to see her adopt this more adult behavior.
