Mini 25TT = tired pups
December 25, 2024
The mini 25TT met and exceeded all my expectations. At first, I was a little bit concerned of the new design, but after a few hunts came to realize The mini 25 TT is built for the smaller hunting dogs, and I could see the performance within my pups, not having the saggy heavy head from the bigger models

Great option for smaller labs.
August 17, 2026
My female lab Pearl weighs under 55 lbs. The TT25 Mini is the perfect option for her. It paired easily to the Garmin Alpha 300 that we have been running with a standard TT25 for the past 2 years. Now we can track the location or make corrections to both of our dogs from that same receiver. I love how I was able to pick both the size and color.

The TT25 collar is easy to use. It does an amazing job of tracking the hound. We use on all of our foxhounds.

TT25 mini
May 26, 2026
Perfect ! We run 4 Wirehaired Pointing Griffons. Each of them wear a TT25. My last purcghase was a TT25 mini it is a perfect as the TT25's we've used for 3 years now. We also purchsed the additional antenna clips and applied them to our existing TT25 collars. These are great for keeping the antenna close to the collar and out of the way.Very dependable - would not expect less from Garmin!!!

The collar picks up great and the extended battery life is also great . I do wish the antenna was shorter, the long antenna may be needed for hounds, but for my bird dog it's not . I have to wrap the antenna around and click it back into one of the holders . Shipping was great and arrived in no time . Would buy again .

All good except the antenna was very long as it was the extended range. A bit too big for my beagles. I swapped it out for a standard one I had, works fine. Standard battery on dynamic lasts a long time.

This is a great upgrade from the TT 15 mini's that I was using. I bought the TT 25 mini's with the short flex bands, and they fit great on my Mountain Curs that weigh 45 lbs. Gun Dog Supply is the place to buy the TT 25's, they will treat you right!!!

Fits my Brittany very well. Like the wider collar and clips to hold antenna. As always, really appreciated Steve's very informative videos. Big difference. Gun Dog Supply always provides excellent customer service and has an experienced staff in MS not out of the country.

Upgrade time

After owning TT 10 collars since they've came out and realizing you can't rebuild them after the collar strap finally rotted away I purchased one of these they are pricey, but you get what you pay for (usually) super fast shipping from GDS too.

Better than my old tt15 mini
December 4, 2025
I'm enjoying this collar so far. I'm just hopeful it lasts. The battery is way better, lasts a lot longer. It seems more durable than the other collars Garmin made. It has a different charging mechanism than the old collars. Didn't know this before purchasing . Not a deal breaker

Mini to fit my Teckels
November 22, 2025
I've been using Garmin for years, and I always had to modify the collar to fit my small dogs (Teckels). I purchased the mini and will now sell all of the others and get 3 more minis and one standard for my Drahthaar. Great product and GDS always provides excellent service.Anthony B Williams

Works Okay for my small Brittany
November 6, 2025
Even as small as the mini is there is a small sweet spot where even the longer pins work for stimulation on my Brittany with about a 12' neck. However, it is working. The mini takes longer for my Alpha 200 to acquire than the TT15 collars. Overall the collar is doing what I need it to.

This collar and handheld combo is awesome. The geo fence feature made keeping my English cocker is shooting range incredibly easy. All it took was tone at the desired range and she would redirect.

So Far, A Solid Collar
October 7, 2025
No issues so far and appears to be working well. The only minor complaint is that my dog's necks appear a little small for the collar (using the nearest hole or the second one). My pointers are around 45 lbs.

Great initial reaction, but time will tell.
October 1, 2025
I run 2 dogs and switched to TT15 with 550 pros 5 years ago. I use the collars and remote every day. The system is excellent when it works, for both training and hunting. The collar/receiver combo has helped me find dogs that took off after deer multiple times and button placement is perfect for training. The 25 has a better profile and is lighter for the dogs. The light is significantly brighter for training at dawn and dusk in the summer. Now the bad, through the last 5 years, I am now on my 3rd 550 pro, and my 3rd TT15 and 1st TT25. Yes I have had 2 collars and 2 receivers fail in 5 years, but because of the GPS and button set up for training I keep coming back. Hopefully the TT25 is more reliable.

Game Changer for My Dog Pack Hiking Business!
September 26, 2025
After one of my dogs went missing for 9 hours, I invested in 13 collars. They haven't failed me! I have used the GPS tracking in dense Vermont woods and found my dogs. Highly recommend. Don't buy anywhere but Gun Dog ... they are the best.
