Pupeye

Pupeye was Popeye's pet dog that was gifted to him by Albert.

RUC's Pupeye
Pupeye's "photo" on the RUC wiki deems him to be a Rottweiler. Supposedly he was a Christmas gift from Albert and was very loyal to Popeye and shit.

Oh, and the wiki stated that Felix the Cat actually liked the dog.

The Real Pupeye
With Christmas coming up and time running short, every member of the RUC scuffled to get any sort of present for Popeye (guy's so insane any gift is a good gift to him). Albert happened to have found a small rabid Chihuahua in the trash in some city and used that as his gift. Popeye absolutely loved it, because it was different from all his other gifts (pipes, crowbars, sandwiches).

The Chihuahua would let out barrages of high-pitches "barks" (if you would even call them that) every second of the day, bites random passing members, and even shit all over the floor. Jafar tried pointing out the "shitting on the floor" thing to Popeye, but Popeye insists that Pupeye was a beautiful loyal dog.

Felix the Cat also really REALLY hates Pupeye.

RUC's Pupeye
The RUC claims Pupeye was killed during an assault by Mike Nnemonic on New York City after he got bitten by Techscience. So they say Tech got the upper hand and bit Pupeye, which gave him radioactive rabies and so he suffered and shit until Felix put him down.

Actuality
Pupeye ran off and came across Mike and co. and bit Tech in the leg. Yes, it was actually Pupeye who did the biting, which makes more sense honestly.

But after returning home he had another one of his rabid fits and knocked over Felix's lunch he had on his table. This pissed Felix off and finally he decided to cut the motherfucker up. Popeye saw this and Felix made up the story about Tech to take the blame off of himself (at least somewhat) and claim he was putting the dog down after he got radioactive rabies (instead of regular rabies, you know?)

Also Popeye easily believed the part of the story where Felix mentioned Mike invading New York City.
