GPS collars are devices worn around the necks of animals, typically pets like dogs and cats, to track their location using Global Positioning System technology. These collars allow pet owners to monitor their animals' movements in real-time, ensuring their safety and helping to locate them if they wander off. In addition to tracking, many GPS collars come with features like activity monitoring, which helps owners understand their pets' exercise levels. Some models even include geofencing, sending alerts if the animal leaves a designated safe area. This technology enhances pet care and provides peace of mind for owners.
