Survival Guide for Turning into a Dog in the Apocalypse

I was following the team to pick up supplies in the supermarket, and suddenly my whole body felt as if I had poured gasoline on it - when I opened my eyes again, my hand was gone! There were only two furry dog ​​paws left, and I wanted to shout "help", but the only dog ​​bark that came out of my mouth was "wuwu"! My teammates glanced at me and kicked me away in disgust: "Raising a useless dog still takes up space in your backpack!" He threw me on the spot among the shelves covered with alien bodies and ran away without looking back. Fortunately, I am the only dog ​​with a human brain in the apocalypse! Before the zombies came around, he stumbled away to the roadside, where he was so hungry that he gnawed on moldy bread crumbs. Chen Mo happened to be passing by and saw me shivering in the corner. Without saying much, he picked me up and took me back to the base. I wanted to hang out at the base and enjoy my meal, but I didn't expect to find half a page of the log in the data room. As soon as the four words "form reversible" caught my eye, I instantly exploded: Damn, I must change back! Now there are only two options: either bite through zombies blocking the way to find clues, or spend your whole life as a dog wagging its tail begging for food - which one would you choose?
