Recovery time?

[PEATMOSS]

My 5 yr old Black Lab seems to be taking a lot longer time lately to recover from exercise. She's always been a very eager retriever and will greet anyone that comes onto our property by dropping a ball or stick at their feet and then sitting, ready to play. She still has lots of energy and retrieves til my shoulder gets sore, but lately she semms to be panting and tired a half hour after exercise. I do not force the dog to work and she will lay down when she's had enough.

Is this any reason for concern or is my dog just getting older?

Thanks in advance for any advice.

I would actually think it is due to being a black lab in the summer heat. Wearing a black fur coat in summer will take away some energy.
