Dogs can learn the scent at any age! However, the sooner you begin introducing the scent, the sooner the pup will begin live alerting. Because of this, I begin scent training at 9 or 10 weeks of age, which is 1 or 2 weeks after I begin training the pup. This timing is because the puppies first have to learn how to learn – that if they do what I ask them to they will be rewarded with treats, praise, or play.
Make sure to have all the necessary supplies prior to beginning scent training so that you can progress at your dog’s pace.
