This doesn’t even seem like the most egregious “weird warning”.
Thinking you can use a pet urine cleaner for fibres on a shaggy dog isn’t madness, it’s just “nope, actually a skin irritant”.

It can be funny when the legal department’s Cover-Your-Ass labelling conflicts with marketing.

Ive heard about the dog owner who washed thier dog, and used the microwave to dry it. Didnt end well.
