I have an almost-three-year-old Jack Russell Terrier, and I like taking her on runs with me. Recently, though, I've been starting to train for a half marathon (13.2 mile) race, so I've been upping my running mileage to about 6 to 8 miles per run, and I'll probably keep increasing it up to 10 to 12 miles in a few months. So far, she hasn't had any problems running the 6-8 miles (in fact, she wants to run more), but I'm concerned that she's running too much and she just doesn't know what's good or bad for her. Anyone have any ideas on how far is too far? Thanks.
My jack russel is about the same age as yours. Since jack russels seem to have endless amounts of energy we got him a doggy treadmill. He begs to go on it. He runs about 10 miles daily. So your dog should be fine. Make sure shes eating and drinking enough though when you run. Some dogs will keep running and not want to stop. Good luck with your marathon!
