What’s a fair daily rate to pay my friend for watching my dog?

So break it down I'm in the middle of a messy break up and crash at my friend will say zennas house paying rent and what not but I need someone to watch my dog during the day until I have her trained not to bark when left alone

So my other friend Zach said she will watch her while I'm at work and told me I can just pay her whatever I can afford which I do want to compensate her I'm asking a lot especially since it has to be at Zach's house since I don't have my own place and I have to walk there because I don't have a car anymore.

But I also only make 16 an hour what do you think is a reasonable amount I can pay her for letting my dog hangout with her for 8 hours?

Other than not wanting to be locked up and alone she is well behaved she will pretty much just lay down and sleep she's 13 years old so she isn't really interested in busting out Windows or nothing.
