This was a polish guy claiming it over a day ago from an over exaggerated Ukrainian report, which was retweeted by an american guy, then added to a video by a british youtuber, then posted on reddit where you saw it. No Ukrainian or russian sources are mentioning it. It's a rumour that grew, but based on nothing unfortunately.

A post on reddit is not a good source to use. By the time it gets to reddit it's already old or reposted with a different title by a bot a lot of the time. It's better to get info straight from Ukrainian or russian channels on telegram if you want up to date info.

That's in vugledar

A polish twitter user over exaggerated a Ukrainian report. This was then retweeted by an american twitter user as though it was true, then added to a video by a british youtuber as fact, and then reposted on reddit, and now people are talking about it in this thread where people think it's happening. Unfortunately it's not real.

It's a great example of how the fog of war works against facts. it's developed into a rumour that's spread based on nothing sadly.

Telegram. Everything you see on reddit regarding the war is from there. If you don't understand Ukrainian or russian it's no use to you.

Most of the records are false claims though. It's not the oldest dog in the world. It's simply someone with an old dog that paid to pretend they have the oldest dog. Its not like there is any cross checking or verification. Literally anyone can pretend they're the world record holder of something if they pay. That's the problem.
