Generally you can tell if a dogs behaviour patterns differ, if they scratch more often, etc. I really doubt there is much risk of chemicals getting into your bloodstream, and if so I really doubt they are dangerous. How many people dye their hair? Quite a few.
Nevertheless, agreed that they're tw*ts!
Maybe not dangerous but unpleasant. In any case, we don't even know whether the dog did start reacting differently - doubt the owners would actually confess what they did has had an adverse effect. Another thing is, you can't really compare a human with animals - this is why many times when you carry out tests on an animal, you get different results in humans and vice versa. That dog has a much smaller body therefore it can reach the level of toxicity much more easily.
Yep, they are ridiculous dog owners.
