GPS collars are probably the most common gps tracking device that are available in the market. It is also the most commonly used tracking device by pet owners. There are various companies that manufacture GPS collars and each of these manufacturers offer special features for their device. There are those that have a battery-saving feature on the collar part. There are also those that have modifiable signals, allowing the pet owner to narrow or widen the range diameter to several feet. There are also those that have strobe lights that switches on when activated, allowing the owner to still identify and locate his pet despite wandering off to a certain distance. Receivers for these tracking devices also have different special features. For instance, there are receivers that also serve as the collar's charger. There are GPS tracking devices that do not make use of a cellular phone modem but rather makes use of MURS (154.60 MHz). This is a particularly economically useful feature because it saves the owner from paying for additional monthly communication costs.

There are also GPS halters that can be worn on pets in order to track its location, in case it gets lost. Again, there are different special features on this kind of pet tracker, depending on the manufacturer. There are those that finds the pet within a mile, regardless of what direction went to. There are those that can display a pet's exact location, as well as its current velocity and movement. There are those that are very user-friendly and does not require installation.
