I foster dogs, and often due to their past circumstances, they are much more stressed and anxious than regular dogs. The pet tag I bought seems to have generally calmed my current foster and it is easy enough to re-charge now and then. I can't talk about the 'science' as I don't understand it all yet, but just because you can't 'see' the effects doesn't mean there are none. And proceeds from each purchase go to helping the street dogs of Cairo - so it's a lovely thing to support!
