The dog days of summer Summer can be a great time for you and your dog to be outside together. But you have to be careful. Leaving your dog in a parked car, even for a short time and with the windows cracked, can easily cause a heat stroke or brain damage.
Summer is also the worst time of year for fleas.
If your dog gets them, their whole environment must be treated, including the yard. If your dog is not treated, it may eat fleas, which could cause internal bodily harm. So while you're out enjoying the nice weather, please make sure your dog is, too.
