TITLE: [DISCUSSION] Can my dog get too much exercise?
POST: Hello! I have a BC/Corgi mix. She's about a year and a half old. Super high energy. 

I have her go to the beach 3 times a week with a "doggy adventure" group. They take a number of dogs out to play together. She gets picked up at around 9am and she comes home at around 4pm. Although beach time is usually only about 2-3 hours, it's usually a very intense few hours. Filled with lots of running, chase, and play. I have a fitbit type tracker and she definitely gets lots of intense running in during that time. 

She comes home pooped. 

I have her go for a calming one hour walk the other 2 days of the week while I'm at work. And a walk, play or park when I get back. And weekends are filled with going to the dog park, the regular park, walks and/or play. 

The doggy adventure group asked if I wanted to go the two other days and she'd match my hour long dog walker's price. I'm afraid 5 days a week might be a little too tiring for her. I mean, she is a working dog so I figure it might be fine once she gets use to it but...

If she gets use to it... would this also cause problems later on? Say I move away from the area and no longer have access to something so highly intensive? I don't want her to get destructive later on if I can't provide her the same amount of exercise. If I have a child later in life and become a stay at home mom. I can definitely play with her and take her out but it'll never be the same as running around at full speed with other dogs for a couple hours.
TL;DR: 
Can a BC mix get too much exercise? Even if not would this be a problem later on if I can't provide the same amount of exercise?
