I am not claiming you said so. But you've rather affirmed again, you have an emotional attachment to your dog, so you won't eat it, so your moral framework is emotional based and is logically inconsistent
You wouldn't much like the taste, or the act of it?
As an analogue, I might have a car I like. The car could be worth more to me than its fair market value because of an emotional attachment, and that may mean I prefer not to sell it. If I'm in dire need of money, however, I'd probably sell it anyway.
