Garmin Alpha TT 25 Dog Collar


No matter what kind of dogs you run or how you hunt, Alpha TT 25 is the slim, rugged and universally sized collar designed to help you build a better dog - no matter the breed.


  • TRACKING: The top-mounted, high-sensitivity GPS and Galileo receiver keeps track of your dog’s location, and the Alpha TT 25 collar transmits that location via VHF up to 9 miles away with updates as frequent as every 2.5 seconds when used with a compatible handheld (sold separately).
  • TRAINING: Train your dog with 18 levels of continuous or momentary stimulation plus audible tone and vibration (when used with a compatible handheld; sold separately).
  • UNIVERSAL SIZING: A rugged yet slim design is universally sized to fit large and small breeds.
  • DYNAMIC TRACKING: Get extended battery life with dynamic tracking based on your dog’s movement.
  • RUGGED DESIGN: The collar features a user-replaceable flex band that can withstand the toughest outdoor environments.
  • LED BEACON LIGHTS: This collar features bright, multicolor LED beacon lights to help you identify and track your dog in low-light conditions. They can be remotely activated and changed from a compatible handheld (sold separately)
  • REPLACEABLE BATTERY PACKS: When using dynamic tracking, get up to 68 hours with the standard battery pack and up to 136 with the extended battery pack (sold separately).
  • AUTOMATIC UPDATES: Receive automatic software updates when Alpha TT 25 is charging and connected to your network with Wi-Fi® technology.
  • PAIR WITH HANDHELDS: The Alpha TT 25 GPS dog collar easily pairs with Garmin dog tracking handhelds, such as the Alpha® series and Pro 550 Plus (sold separately).
