Is it safe to irrigate a dog's sinus?

well... i would not squirt any water or anything not intended for dogs, up your dogs nose. first off, that would irritate your dog even more, second, its not the type of thing you want your dog to possibly inhale. dogs get sprayed by skunks all the time. you can either take him to the vet in the morning to be cleaned and checked, or you can just do the old fashioned tomato juice bath. if it got up his nose, i would just take a steamy hot washcloth (not soaking wet) and gently wash his face with it and hold it on his face for a few seconds so he can inhale the steam to clear it up a little, then a cold washcloth right after and just pat gently to let the cold relieve some of the irritation.
i do this with my pup a few times a week just because he has sinus problems and always has those crusty tears down his face and he just lays his head in my hand and moans lol so it must feel good and relieving to some extent

dont do that!! bring it to a vet if he is irritated...you dont know what could both him....would you like that done to you!?! what if its not good for him would you like to have that chance on you??
