My dogs need to go for walks and the oldest (16 yrs old) doesn't care to walk down the stairs any longer, so I started taking them both for short walks.
Use the 'old' boxes of baking soda from your fridge and freezer for cleaning your pots and pans, washing up after greasy or yard work, final rinse on your dogs bath, cleaning jewelry stones.
My feet were moving while my vehicle received 4 new tires. I didn't sit and wait the hour in front of a TV in a waiting room. Previous times I brought a book, this time I brought my dog and we walked nearly 4 miles during the hour appointment.
Mix together a quart of hydrogen peroxide, 1/4 cup baking soda and 1-2 tsp Dawn dishwashing detergent. Add warm water as needed to make enough solution to cover the whole dog. Rub it in well with a sponge and then rinse with warm water. Repeat if necessary.
When I don't feel like walking I tell my dogs that we are going for a walk. They understand what that means and their excitement is enough to get me excited. If the excitement weren't quite enough then the thought of how disappointed they would be if we didn't go and the looks I would get would be.
When I start to feel like I've screwed up and want to toss in the towel I look at dogs. They have the "if you fail the first time, keep trying" motto in life. If a dog wants a bone he keeps going until he gets it. Which reminds us a bad day is just a sign to get up and try again tomorrow.
Some days when I don't feel like working out I look at my dog and see her bursting with energy. Taking her to the park, walking or running with her ends up being play time for her and excercise time for me! She usually pushes me too!
