I love wearing leggings with a t-shirt if I am walking my dog in the morning when it's still a little cool outside. Look for shorts with an elastic waistband and a shirt for those days you need to walk your furbaby during the hot summer afternoon. Very comfortable and chic at the same time!
I always advise wearing walking shoes. I don't know about your dog, but mine likes to walk FAST! I need appropriate footwear to keep up so he can have fun too! Add a pedometer to keep up with your daily exercise routine. You will be surprised at how many steps will add up over time!
Don't forget the sunscreen and sunglasses- even if you are just outside for 30 min.! Sun protection should never be forgotten.
Do you have a dog? If so, what do you wear while walking your dog?
