The media could not be loaded. This w collar is the best thing I’ve ever purchase for my dog. EVER. He is an 11 year old pitbull that has never had a good recall. He is the kind of dog that knows his commands, is obedient on leash, in our fenced yard, and obedient in the house. BUT the moment he can escape, he will! He has been this way since he was 3 months old. He will dart past, rush, and use any open door as an opportunity to run. He will run for miles and hours chasing squirrels, birds, cats, etc. and will quite literally ignore all attempts to recall. Now that he’s a senior dog, these escapes happen much less often, and he will eventually give up after he’s being chased for a while. However, we are getting a new puppy and really didn’t want her to learn from his bad behaviors. I researched for a few weeks before we decided on this brand. I figured if hunting dogs could be trained with this thing, so could my boy. Y’all, I can’t believe what this collar has done to my dog! Here are the PROS: -remote is easy to use and fits well into my hand -having tone, static, and vibrate are great options and avoid unnecessary static corrections as he responds well to tone by itself. Most times I don’t even need to press the tone button. -I use static levels 1-2, and he’s totally responsive. -range is phenomenal. Can go from one end of a park to the other and have control over him. -He no longer darts out the door. -I can walk him on a leash without his prong collar. -he can walk outside with me off leash and comes as soon as I say his name. -he can be in the run with our chickens and doesn’t even flinch when they come near. -on walks he is rarely, if ever distracted or interested in chasing ANYTHING -As soon as I take the collar off of the charger in the mornings. He is at my feet wagging his tail and waiting for me to put it on. He’s a happier dog now that he has so much more freedom! Now for the Cons: -despite following the collar adjustment guidelines, my boy developed sores on his neck. I would suggest checking regularly in case any develop. He was wearing his collar for long durations because I didn’t want him to escape and then not have the collar on to reinforce my training, thus destroying all of our progress. Once he became more reliable and trustworthy to respond to his recall, I now leave the collar extremely loose(so he can at least hear the tone), and adjust tighter when we go outdoors. -both collar and remote have to be charged nightly, or you risk it not being fully charged. I made the mistake of skipping one night. It worked the next morning, but was dead that evening when I needed it to be working. I can miss a night here or there, but if we will be out all day(using the collar),I have to charge it in the morning to be safe. I would recommend charging as soon as you remove it. -personally, the lanyard is uncomfortable hanging around my neck. I would much rather prefer there were a clip on the remote so that I can attach to my waistband. -there are times that I press the tone button, and it’s delayed in relating the beep. I notice this more often if I skip a charge the night before. -vibration doesn’t seem to have an affect on my dog as far as being a correction. -using this device requires already having a dog who understands basic obedience commands. You can’t just strap it on and start using static and expecting your dog to be an angel. *In the wrong hands, this collar can do more harm than good. It requires research and technique to properly train with e-collar* Overall: research e collar training techniques, be patient, and enjoy. Highly recommend!!
