How lucky you are to have a dog to run with!

Several things to be aware of -

Giving water every 15 minutes or so is a good idea. It will keep her cool & give her a break. Constant pounding can be problematic on connective tissues if the dog isn't acclimated.

When she slows down, try giving her water & taking a walk break. Then start up again. If she's still pretty slow, I'd say she's had enough fun for one day. Yeah, they hate it when you drop them off, but we're supposed to be the smarter species...

Don't shave her. That hair gives her protection from the sun & actually keeps her cooler. This breed is a cool weather type of dog.

Run on soft surfaces when possible. Many dogs don't display orthopedic problems until it's serious.

Do not put booties on your dog. They sweat through the pads of their feet.

Run during cooler weather. If you suspect she is overheating, cool her off by putting water on her belly and paws. Get her home quickly & submerge her in cool water. Dogs pant, but if you see her stumbling, see her tongue really hanging out, etc., err on the side of caution.

Make sure her nails are short. Longer nails can affect their gait.

Hope that helps!
