I'm not sure about the being ok part, but I as a human being will never be able to be excited like a Labrador puppy. Except maybe on drugs, but I don't know which would allow that level of joy and neverending appetite.

I'm fat already, so that might be a good thing though.

The dog has swimmer's syndrome.

As far as anyone can tell, the original is from a tiktok animal "funny" explotation/abuse account.

They have several repeat videos of this dog doing the exact same behaviour, they seem to keep them in tiny enclosures, and keep feeding it milk. Milk is not good for dogs, especially not that much. There's no guarantee that they feed the dogs regularly or humanely.

It's difficult to actually tell context because of the nature of these types of channels. Labradors can have food aggression, especially pound dogs, that needs essentially "dog therapy" over time to abate. Considering animal abuse is rampant on the channel in general, I don't have high hopes here. The channel posting this specific dog over and over does not give context.

The last few videos with those two dogs does show some progress with the labrador starting to gain walking ability, so maybe they are trying to rehabilitate, but they're still giving them insane amounts of milk. They don't look bone thin, exactly. Again, hard to say with no context.

If there's an original source with more information, chances are it's on some website somewhere in chinese, which can be difficult to convince browsers in english to find :/ Language barrier. I've spent a few hours looking, including trying reverse image search. I've seen this a few times and memeified animal abuse bothers me, so wanted to know if it's... not. If someone knows actual context with source links, I'd like to know.
