Okay I really hope there's a follow up to this

You really shouldn't be allowed to have a dog.

I see fights involving little dogs all the time, usually when their stupid owner decides to let them in the "big dog" area at the dog park, almost every little guy that goes in there gets snipped at or worse. Because even though small dogs are "real" dogs they're annoying as shit.. I have also seen it where the neighbors have a super annoying small dog that will bark like crazy, knowing it annoys the big dog and taunts them from the other side of the fence, thinking they are unstoppable. When finally one day, they step into the big dogs territory and are considered a threat.. I haven't had these happen to me personally but I am not surprised

tiny hot dog?

That's not funny. I have a little dog and keep her on a short lead all the time and she is constantly attacked by bigger dogs whose owners don't leash them for some unknown reason. Do the world a favour and never get another dog.

that's horrible OP. I'm sure you feel bad, but the circumstances leading up to this probably left it out of your control. Did the dog come into your yard? or did your dog get out? R.I.P little doggie.

can cannibalism happen in dogs..storage and I never heard of this before

How much you wanna bet the little one was trying to start shit? Either way, this could use a follow-up. So many questions…

Seeing your location, maybe your dog was hallucinate from malnourish and thought small dog look like potato.

WTF?!
