If you need to warm up in the cold, head on over to Starbucks (or your local coffee shop if they give you the option), grab yourself a hot latte (or even better, mocha) and a Puppachino for your dog (it's ok, it's really just a small cup of light whipped cream).
The District at Green Valley Ranch is always beautifully decorated for the holidays, making for a fun and aesthetically pleasing walk with your dog. Many of the shops are dog-friendly as well, so you two can stroll around at your leisure. We recommend going in the evening after the sun starts to set but before shops close, as you'll get the most picturesque experience.
Sometimes hot days are just too hot to jump around from the air conditioned car to the blazing heat of the outdoors. Save yourself some hassle and dress warmly, then check out a series of nearby dog parks to get to know their layouts and features. When it does get hot, you'll then know which are best to frequent due to the availability of shade or water features.
