Is Sniffing good for dogs?

Perhaps more importantly, for all dogs a chance to sniff fulfils a major part of their sensory needs - as much as physical and mental exercise does and as much as play does. Sniffing makes them happy and gives them an outlet for their hard-wired natural behaviours.

How much does sniffing tire a dog out?

Depending on your dog's abilities, a 15-minute walk won't do much to tire them out physically, but that same amount of time spent sniffing and processing scents will satisfy their need for mental enrichment. Remember, walking the dog is supposed to be about the dog, not you.
