Nike's nostril has a pink bump inside, help?

vet's your best bet and in addition to Amanda's good guesses as to cause add foreign bodies like foxtails if you have those or other seed pod type deals. Some times of the year and in some areas those are NOTORIOUS nose gitter inners!

All the best that it's something easily fixed!

Definitely vet -- I honestly doubt, from what you said, that it's a tumor because it came up too fast +sneezing.  However, the vet should be able to remove a foxtail (you usually can't) or stinger if there's one there and give some relief - it won't be a wasted vet visit in *any* event.

 Thanks for the suggestions, everyone.  I'm glad that general consensus is that he probably has an irritant or stinger in there.  I'm so relieved that it's hopefully something small.  I'm a classic worrier, though, and my mind always jumps to the worst case scenario. 

I called the vet this morning and set up an appointment, so I'll just have to wait and see what he says.

Thanks for relieving my mind!  

Please keep us posted!  With Morrison's huge snout this is probably something I should know more about.

So...Nike's fine. Lol.  You'll never believe what the bump was.  Turns out that Nike's left nostril is black pigmented, and the right one (the one I was concerned about) is not pigmented so it's pink.  Basically, when he was sneezing so much the other day, his nose did get inflamed, and all I saw was a swollen pink nasal cavity.  

But, like the vet said, it's better that I notice these small things than be oblivious!  The vet gave Nike a full physical in order to make the office fee worth it, which was nice.  We talked about Nike's heart murmur, and he cleared him for obedience class and agility in the future.

Thanks again for letting me post in my frantic worry.  I'm glad I have an understanding forum to share with!
