Running with my dog

Question
I have what I have been told is possibly either a rottweiler/lab mix or mastif/lab mix (he was a stray). He is all black and weights about 85 pounds. I run with him about 3 miles a day, and we have been doing this for the last 6 months. I am wondering if that is safe/ok for him especially with summer coming up. If it is, I would like to take him on longer runs if possible. How do I know how far is too far, and what are signs I should be looking for if he is getting too hot or tired?
Thanks for your help.

Answer
Hi Sarah!

The biggest threat for your dog while running in the summer is the heat and humidity. Early morning or evenings
when it has cool off, are the best times for summertime running so you can avoid the hottest time of day. Even then, if it is too hot, don't do it. Don't let your dog exercise in hot weather.

Most heat exhaustion occurs on semi-hot days rather than on the really hot days when it's more obvious that you shouldn't be out running.
Dogs can quickly overheat, especially if they have a dark coat as your dog has. Larger dogs are more prone to overheating than mid-sized dogs, and the fact that a larger dog might be short-haired does not change that. If you see signs of overheating, stop immediately and cool him down slowly with cool or tepid water (not cold). Signs of overheating include the following:

Excessive panting
Increased salivation/ foaming at the mouth
Gums are deep red
Dog starts to fall behind
Increased heart rate
Dog looks distressed
Vomiting
Diarrhea
Weakness, or unable to stand

You're probably aware that dogs do not sweat. They dissipate heat through their paws and mouths. Plan your running route to allow drinking stops, and let the dog run through puddles, if there are any.

Try to run on trails which are shaded and soft.

Your dog may need more water than you do. With time, you'll learn to judge the dog's water needs based on the temperature and on the length and speed of the run. Don't forget to bring a water bowl.

You asked about taking the dog on longer runs during the warmer months. I wouldn't push the dog in the summer, maybe begin increasing the length of the run in the fall, after it's cooled down.

Just a little common sense is all it takes to ensure a trauma-free summer with your favorite companion. And maybe a trip to Tastee Freeze for ice cream (vanilla, not chocolate)!

I hope this has been helpful and I wish you the best of luck!Please keep me posted and give him lots of kisses for me!
