I purchased this vest in anticipation of the upcoming summer months in Texas. The summer months are brutal here and most folks get their dogs out for walks very early in the morning; however, with a young child in the mix, this doesn't always happen. Having this vest available gives us more flexibility if/when we need to take her out when it's already feeling very hot. My dog is also a short snout breed, so this also gives me some peace of mind that, in addition to other steps, I'm doing what I can to keep her comfortable as the weather changes. Great idea, Ruffwear!
