One of my problems with this is when someone in the video said "Some even say a new look can help the dog's self-image."
The dog's self- image? Are you serious? It's not a person. And I wouldn't quite like being dyed to look like a turtle either. But if a human wants to change their hair color, so be it. But a dog is NOT going to have human emotions and be like "Oh,I look pretty!" and even if a dog did have human emotions, it might be like a little boy in a tie and be like "get this stuff the heck off me!"(or a baby girl in a frilly dress....or...you get the idea...)
A dog's self image is not going to be lifted by being dyed to look like a panda....for crying out loud.
And most dogs probably wouldn't like that anyhow...............my point is, we don't know. It is not a person and cannot tell you if it likes that or not. And a dog is not going to be affected by its look like a human.
It sounds more for the owner's self image, if you ask me.
Best wishes,
