It was raining this morning. My dogs did not care. We went for our walk as usual. I was reminded of Dr. Robert Kushner. Dr. Kushner is professor of medicine at Northwestern University Feinberg School of Medicine where he focuses on obesity. He has published over 140 medical articles as well as several books on obesity. My favorite is "Fitness Unleashed: A Dog and Owner's Guide to Losing Weight and Gaining Health Together". Dr. Kushner is bullish on dogs: "Who would know that a dog leash, for many, is more motivating than an expensive gym membership?" Kushner teamed up with Hills Pet Nutrition to develop a program to combat the combined obesity epidemics in people and dogs. The program is simple. Get a dog, get a leash, get going.
For more on this topic, and a bit of whimsy, try "Fit as Fido" by Dawn Marcus. Her chapter headings give you a hint of her style: Eat like a dog (no table scraps or leftovers from other's plates); Play like a Dog (more time outdoors on your feet); Sleep Like a Dog (make sleep a regularly scheduled priority); Teach an Old Dog New Tricks (Adopt a life-long pattern of curiosity).
The worst walk is always better than no walk at all. You will only regret the walks you don't take.
