Hi, I'm Dr. Deb. I will do my best to assist you today.
Can you tell if Charlie has any nasal discharge coming from either one or both of his nostrils? Does he appear to have any pain anywhere that you can localize? Can you count his respirations/minute?
Any swelling anywhere on his face? Could he have been stung or bit by an insect or spider?
The symptoms that you describe are not associated with one particular problem. Dogs can lick their noses because they have a discharge and sometimes it's hard to tell if they do or not because they lick it away so quickly, but you can look up his nostrils to determine if there appears to be anything there. Dogs can also lick in response to fear/anxiety/pain. The breathing and being unsettled could also be in response to fear/anxiety/pain. If he was stung or bitten, I would expect at least a little bit of swelling around the nose area.
Depending on your responses, it might be appropriate to try either either bufferin or benadryl or it might be more appropriate to monitor the situation for a little while longer if he doesn't appear to be in great distress.
The average dog takes between 15-30 breaths/minute so this will give you a guideline. Dog who are in pain or fearful or anxious can oftentimes have elevated respiratory rates; other problems can cause this as well (heart disease, lung disease, for example).
It looks as if you are offline, but I would be happy to discuss this in more detail when I have a little more information.
Sorry, I haven't gotten back to you sooner but I have been off the computer. I'm glad that Charlie seems ok now but it is had been something poisonous, I would have expected him to be vomiting or showing different kinds of symptoms. An allergic reaction is certainly possible or even if not a bite or sting, then perhaps he stuck his nose somewhere that he shouldn't and it was more of a "twinge"...not enough to cause swelling but just enough to feel uncomfortable.
This is one of those situations that if we just get him to talk, we'd have it all figured out:) In any event, I'm glad that it doesn't seem to be anything serious and that he's ok.
