Our male lab is 2 1/2 years old and is very easy going. However, we are having an issue that is not going away. He lives to sniff and follow any scents that are around. When he catches one he likes he will run/follow it to the exclusion to everything else. He is %100 focused on the smell and nothing but the smell. Are there any resources or trainings that would incorporate his nose but teach him to be aware of his surroundings and commands?
