Yes, it is. In fact, if your dog is showing signs of boredom (such as chewing on things they shouldn’t) a lack of interesting sniffs may be part of the problem. This is especially true for tracking and hunting breeds.

We have a Blackmouth Cur, and one of the things we do for fun is hunt feeding. Basically we take a portion of her dinner and scatter it around the yard, then set her loose to go find it. Tires her out really well. She loves rooting around for all the little bits of kibble.
