Take advantage of new things to see and someone else's air conditioning by going shopping. There are several unique dog or pet-centric stores throughout the state, like Lucky Dog's Place. Go shop around or get your furry friend a new toy, leash, or collar!
When it gets too hot, a haircut is almost always a great idea. It costs little and will help your pooch stay both cooler and cleaner. If you can, try to find a few smaller shops (Omaha and Lincoln are great places to start) or you can always revert to the big pet shops for a tried-and-true default.
Outside of L.E. Ray, Walnut Creek may be the best water-centric spot for you and your pooch. It has some beautiful scenery and offers another place for your dog to take a dip and cool off.
