did my dog over excerise?

Hi,

My 11 month old energetic Cairn Terrier excerised for at around 2 to 3 hrs daily these days.

I released her to run around in backyard and played soccer. I walked her to meet her friends. And then my dad took her for an hr walk after dinner.

is it too much for her?

I heard dog will get heart attrack if they didn't get enough rest.

thanks
Alice
