Context: My border collie had to be put down due to a neurological disorder that could not be treated.
Speaker 1: It is so difficult to have a pet pass away, I really miss him.
Speaker 2: Aw I understand that, I have gone through that myself and it's very hard. When did this happen? 
Speaker 1: Over the summer, he started acting strange so we took him in for testing.
Speaker 2: Oh no I'm very sorry. What kind of pet? 
Speaker 1: A border collie, he was a great doggie.
