Universal Fit for Every Breed

The Garmin Alpha TT 25 GPS Dog Training Collar uses a rugged yet slim housing that fits both large and small breeds. A user-replaceable flex band lets you refresh the strap without replacing the whole unit. A built-in multicolor LED helps you identify your dog in darkness. This collar is made for hunters and trainers who need reliable tracking and correction in the field.

Extended Runtime with Dynamic Tracking

The standard battery pack delivers up to 68 hours of operation, while the optional expanded pack doubles that to 136 hours. Dynamic tracking automatically adjusts GPS update rates based on your dog’s movement to conserve power. When charging on Wi-Fi, the collar installs the latest software updates automatically so it stays current without manual effort.

18-Level Stimulation Requires Compatible Handheld

Training functions include 18 levels of momentary and continuous stimulation plus tone and vibration, but they only work when paired with a compatible Garmin handheld sold separately. Without that handheld you cannot send commands or receive the 9-mile tracking range. Buyers who want an all-in-one unit or who do not plan to buy the handheld should look elsewhere.

Questions about this item

How do I install the collar on my dog, and which step do owners often get wrong?

Fasten the user-replaceable flex band snugly so the contact points touch the skin, but leave enough room for two fingers underneath; the common mistake is leaving it too loose, which breaks stimulation contact.

What maintenance or replacement will this collar need later?

The flex band is user-replaceable when it wears or stretches, and the rechargeable battery pack can be swapped for the expanded pack to double run time.

What limit shows up first during a long hunt with continuous tracking?

Battery life reaches its limit first — up to 68 hours with the standard pack or 136 hours with the expanded pack using dynamic tracking.
