A dog's nose is an amazing thing. It is so sensitive and smells things we can't - termites, drugs, illegal foods - even some cancers - to name just a few. I never see boogers in it and it never needs blowing!!!! Could we do that? Nope. I am sure Zack must have been a beagle or bloodhound in a previous life as his nose is always glued to the ground. I do so much with Zack already but may be I should take up tracking !!!
