Watch out passers by, here comes Sandy! Those are the thoughts that run through my mind when my dog and I go to the park and use the Pet Gear Happy Trails Pet Stroller! My dog used to love to run or walk on a leash beside me while I'm running or walking, but she's older now and can't go as long or as fast as I would like her to. I couldn't just leave her at home when I went for a run or walk because she was used to going with me. Then I found the Pet Gear Happy Trails Pet Stroller. What a great idea. This stroller is better than the stroller I have for my kids! It is so easy to maneuver and get around objects in my pathway quickly. My dog absolutely loves being in it and gets so excited, waging her tail and whimpering, when she sees it. I initially thought she would refuse to get in it because of the cover, but she loves it. The cover blocks the sun in the warmer months, and it is fleece lined for the winter months. It is even waterproof for rainy days. It has front swivel wheels and back brakes just like a child's stroller does. I love this stroller and am so glad someone suggested it to me.
