Since summer is here with 110 degree or more temperatures, please remember to not walk your dog on hot sidewalks or asphalt, and if you must, please use booties or at the very least, heavy socks! If you need to walk him/her on concrete or asphalt, please do so in the early morning or late night. The best rule of thumb (or paw, if you prefer) is to literally touch the ground with your hand. If it is too hot to the touch for you, then it is too hot for your best friend's feet.
Booties may seem too difficult to teach your dog to get used to, but they work! And you can indeed teach new tricks to older dogs. They may balk a little initially but if you are patient and reward them for tolerating the booties for even short periods of time, you can walk anywhere in the hottest part of the day.
Google "dog booties" and you will find a variety of vendors that have boots of all types available. Some sporting goods stores have them as well.
Please consider their feet. And if your dog is a swimmer, being in the water for a while can soften up even the toughest feet, and thereby make them even easier to burn. Protect those tootsies!
Here are some facts to consider:
If the air temperature is 77 degrees, the asphalt temperature is 125 degrees.
If the air temperature is 86 degrees, the asphalt temperature is 135 degrees.
If the air temperature is 87 degrees, the asphalt temperature is 143 degrees.
