In need of help to take care of my dog

In need of help to take care of my dog (regular=dog walks; not regular=dog care for multiple days at a time)

I have a very cool rough collie, which is 11 months old at the moment. He is very nice and good hearted. No aggression of any sort. Only down side is that he does not listen the best but he still does listen some.

I primarily need help 2-3 days (Mon - Fri) a week for someone to come over and walk Linux at around 2pm. A single hour walk should be fine.

Secondary, I would need someone I can trust to take care of the dog for 3-4 days at a time when I need to travel. This is usually not regular and we plan it all ahead of time.
