Hi,

I noticed a small white spot on my 10 year old Lab mix's noise. It's just a different color, it's not a growth or anything. Does anyone know what this might be? She had it for about a year now. It seems to be getting bigger slowly. Someone told me it could be a sign for hypothyroidism, is this true? Should I be worried and go to the vet?

Thanks for any ideas!
