Good grief.
If a dog gets too hot it will pant. If a dog is panting, you'd think the owner would know enough to take the coat off without an expert saying so.
Dressing or not dressing dogs is a personally preference and can't be linked to any health benefits or risks if it is done correctly unless the dog is allergy to fabric or dye. It does not cause injury and it is the owner's choice.
Don't they have anything better to do like arrest people who don't feed their dogs or leave them chained with no shelter?
