I tried lostmydoggie.com after I had previously tried another lost pet service. The other service did not work and wasn't reputable, but lostmydoggie.com was a lifesaver, or should i say dogsaver. I used both their neighbor amber alert and their shelter/vet mail service and within 3hrs of placing the phone calls, my dog was found. Their customer service is actually concerned about your lost pet as well. They called me before the alert went out to get all the information correct and then followed up after wards as well. I would recommend them and I give them an A+.
