[nagdu] How often does a dog have to work?

[Lisa]

Hey everyone!

I would like to hear your opinion on the following question.

How often does a guide dog have to work?

By now, I've heard so many different things. Some say a dog has to be 
working every day or otherwise it would get frustrated, bored, angry, 
depressive... And others say it's completely fine to work the dog as often 
as you need to and in the mean time let it just be a happy dog, with play 
time and paying attention to it of course.
I've also heard that there are dogs who really demand to get out and work 
and others who are fine with one or two lazy days in between.
So, what do you think? Does it depend on how energetic and active the dog 
is? What if I twisted my ankle and would want to cure it for five days or 
so? Would it be okay to neglect guide work then?
Just curious.

best
