A voice-enabled, waterproof, GPS-enabled cell phone from Pets Mobility tracks your dog’s location. It’s also a two-way cell phone, with an auto-answer feature that puts your voice on speakerphone. You can talk to your pup and he can respond with a bark. The doggy phone has a “call home” button so if anyone finds him, they can use the phone to contact you.

I’m not sure I see the value of talking to my dog, but the rest of it makes sense.
