When it comes to scenting ability, what kind of experiences have people had? Have you noticed any differences between breeds/types, or is it more down to individuals (regardless of breed/type)? Do dogs tend to stick with a preference for either ground or air scenting, or can they learn to do both as needed? Can practice or training improve scenting ability, or is a good nose something a dog either has or has not? Has anyone noticed any difference in scenting ability with different types of feed? I would love to hear about literally anything to do with noses.
