Everyone hunts for a GPS tracker without a subscription and with interesting features.  Despite the demands and usage,  these dog accessories have some drawbacks.  A tracker without any subscription uses open frequency with limited geographical positions. It cannot track your dog beyond the range.  Also, without a subscription plan, your tracker might take 4 - 6 minutes to track your dog, but till it does, your dog reaches some other location.   So, it might get difficult, but not impossible, to track the exact location.  With a subscription plan, your GPS tracker can track the exact location but the size might get bigger.
