I liked the writing, it wasn't too descriptive and it felt genuine like a real dog owner would.
I was expecting that one of the options I chose was going to be the last so I chose carefully until I realised that I was going to have to go through all of the options before the game progressed. That made me a bit impatient and I started to skip through it. That hurt the ending a little because I was reading too hastily and cared less about the details in the writing.
Having said that, It did get me a bit upset because I fear the day I face this decision with my dog, so well done!
