I've never heard of Vicks being used for that. I do use it on my boys when I have a female in Season or when I'm at a dog show where a female is in Season. But, I just take a bit and rub it on the chest......keeps them from getting the scent and going wako.
I don't think that his inhaling it is detrimental, but I'd check with your vet about his licking it. And find out why your dog has breating issues....he could have a sinus condition.
