Too Hot

There is not a hard and fast temperature that makes it too hot, but a good rule of thumb is 90 degrees and higher is too hot. On days with very high temperatures, the best idea is to modify your walk times to be early in the morning or late in the evening. These times of the day are cooler and you won’t have the direct sun beating down on your pup. An even better gauge than just the temperature is feeling the sidewalk or road you will be walking on. We use the 5 Second Rule: Place your hand on the pavement and if it is too hot for you to hold there for 5 seconds, it’s too hot for your dog to walk on it.
