Ha ha!! We should put your 3-year old with my 4-year old labrador retriever!! He seems to enjoy many of my fragrances as well. Always, and I mean always, after I spray something on, he comes up and wants to sniff. Some scents he "just" likes and walks away after a sniff or two, others he would like to stay there for couple minutes and sniff my arm over and over. He seems to be enjoying himself, exploring the various scents. Kind of crazy, I know, but... what can you do other than share the love of fragrances with your best bud?
