The new product from a company called Environmental Studies, integrates GSM and GPS to allow you to SMS your dog's collar to locate the missing dog. Apparently, once the collar is called it provides the user with a location that is sent back to the owner for use in plotting a location. The company claims it can be used with almost any GSM cellphone capable of viewing maps, although they don't discuss software for the phone. Limitations to the collar are GSM service and satellite coverage where the dog is located.
It seems like GPS is showing up in everything these days, including dog collars which can help you locate your lost pooch should they run away. Read more after the jump.
