Yup - according to Distractify, this trend was first seen at the Royal Paws Pet Salon in High Point, North Carolina. It truly baffled staff, to the point where they posted a photo of it on social media, at the same time clarifying that they wouldn't be offering the service themselves.
In a Facebook post, the salon said: "I just thought I would let everybody know the latest creative grooming trend is glitter balls! Please know that I love doing creative, but I will NOT be doing this. Posting for your entertainment."
This was posted on 24 January, alongside a whole host of pictures proving that this actually is a thing that people are doing.
Usually with trends, there is some kind of vague logic or catalyst as to why it's happened, but with this one, Lord only knows.
Naturally, a lot of people are very concerned about this practice, and with good reason too. However, we are assured that the glitter used is edible and stuck on with corn syrup. That means that at least no dogs were harmed in the making of this abomination.
After all, we all know what gross stuff dogs get up to with their mouths on a daily basis.
As ever, there are a wide range of opinions on the Internet about whether this is abusive towards the animals or not.
One Facebook user commented: "People saying this is animal abuse must not know the true meaning of animal abuse."
"The animal isn't harmed, they aren't neglected, actually it's the complete opposite since it's part of a grooming service. Now, is it disturbing? Absolutely.
"Harmful to the animal? No. They use sticky corn syrup and edible cake glitter."
