I am amazed! My 2 years old German Shepherd is a super smart dog that could be also a bit of brat. She does heel but given the opportunity and in the absence of the leash, she would go running towards another dog to play! Not anymore! This collar literally made a HUGE change in her. She did heel best and even without the leash. Now mind you, the device is not magic, and I have been working with her, we have a great connection and training was in progress but this device did it. I shall post a video tomorrow of this.
A word of caution: use the remote on your own hand, back of the hand as the palm is sensitive, to get an idea of the levels. I didn't feel anything until level 20, and at 25 I felt a decent shock, so I won't do that anymore. It seemed that once the dog tuned in the remote, 10 was all that was needed, on day 1! If you aren't getting the response that you want, make sure that your dog understand that she's supposed to do something (plenty of video and tutorials online) and that the collar is tight enough (but not too tight). Avoid high levels to start with as I assume that they would be painful and not necessary if you make your dog understand the device, based on level 25 that I shocked myself with!
To be continued.
December 22: I am so impressed with Dogtra that I ordered a 1900 one also. I think k they're fantastic for training your dogs, specially powerful breeds and bigger dogs. The motivation for 1900 version was being water proof and longer range.
Unfortunately, my 208C started ti be inconsistent. The levels don't work accurately anymore. Sometimes level 8 works great but other times even level 25 doesn't give any stimulation to the dog nor my skin, then randomly works another time. This is dangerous and unreliable. I've tried cleaning/ wiping the stimulation rods, pulling back hair and different tightness.
Based on other reviews, I assume this is a faulty unit and exception. Based on the difference that it made for traning dogs, the built quality and getting solid recalls, I leave 5 star for the item. I shall review the 1900 unit after a month or more of use.
