<human>: Three months ago my sister, Claire, bought a puppy. She works full time, but really has wanted a dog for a long time. Since I am doing online classes, I agreed to raise and look after the puppy while she is at work. 

From the beginning I told my sister this was temporary- I specifically have been training the dog to fit within my sister's lifestyle. I have the puppy house and crate trained, and very well socialized. My sister funds the puppy but I put all the effort into raising him.  

Claire works four days a week- 10 hours each. In the morning she makes me get up to take him out, then she feeds him. While she is at work I train and socialize the dog, and do my classwork. I try to give him plenty of puppy playtime, but also am getting him used to long hours alone. I figured my sister can hire a dogwalker for a lunch walk.

When my sister gets home from work, she greets the puppy and then goes on her computer. I am expected to take him out. If she wants to take him to the park, I am expected to go. I do his nightwalk.

On her days off, Claire still expects me to take him out. Likewise, if she wants to take him to the park, I have to go.

Is this fair? I spend all day with the dog, so is it too much to ask she take him out  to go potty?

Can you give me a shortened version of the text?
<bot>: Sister doesn't take her puppy out to go pee/poop on her days off. Am I asking too much to want her to?
