Just means more rats to eat.

I can't speak for my fellow Fereldans, especially those with the preternaturally intelligent mabari, but as for other dogs? In the end, they're merely animals. Should starvation truly set in, I might be driven to eat my own. But all other alternatives at that point would have been considered.

I'd much rather eat a cat first, though. What brought about this morbid line of questioning?
