"Understandable! Which type of beagle mix do you think he is?"
To be honest I haven't given it too much thought! I like leaving it a bit ambiguous, I've had rescue dogs where you could see a primary breed but then there's a mix of a few different other breeds that are too hard to pin down. So in honor of them, I'll leave it ambiguous (for now).
And thank you for the grammar/spelling corrections! Those are incredibly helpful. Keira is the correct spelling, so that's a pretty major issue considering that's her name label! Good catch.
