After much back and forth, I picked up a Dogtra with some Cabelas cash I had going to waste. Finn had been doing very good in his obedience training but we were having issues off lead around the house. Away from home off lead, he was fine and would come when called. At home, not so much. The problem started when he met the neighbor dogs and was then invited into their house. He found the food bowls. After that, any time he was out and got free or I tried to let him off lead, he'd bolt to their door and scratch at their screen. No good. I tried everything I could think of to break him of this, but he had this shit imprinted that that house was where there was good food. Next door to them were kids who love playing with him. Another place to bolt to. It got so bad that he'd bust through the front door, knocking over my wife, and be gone. He was 6 months old and 60 pounds at the time. All I could see was a future with Finn being over 100 pounds and doing as he pleased. So I worked with him. Lots of "stay", that didn't work when he got excited. A long lead staked out. That ended with him flipping himself over many times and I started worrying he'd break his neck. He's a dumb lab sometimes.
I got this Dogtra because it had vibrate and shock. I didn't want to shock but wanted it for backup. I put the collar on and let him wear it a few hours a day to get used to it. After a few days I tried out the vibrate on him as he bolted out the door and to the neighbors house. BOOM. Dead stop. I saw the confusion and called him back to me. He came. I praised his return. Holy shit it worked. Every. Single. Time.
Now we're 2 months on and he wears it daily. It goes on in the morning and he gets excited because he knows it time to go outside and play before I leave for work. I take it off while he's crated and it goes back on the second I get home. Hell, he's even picked it up off his crate and brought it to me. I have shocked him maybe 5 times and never over 30 on the settings and I tested it all the way up to 50 on me. 127 on a friend, but he's weird and likes pain. He knows his boundaries now and it's amazing to watch. As a test, because I thought it was just the collar making him stay in our yard, I took it off. He would see my neighbors and walk to the edge of our property and promptly sit down. While he's focused on them, he's not bolting into the road and he's not trying to tear through their screen door. He then will come when I call him back to me. His recall has become much better, his minding his manners as well.
I wouldn't say they're for everyone, but it's worked wonders for me. My plan with Finn has always been to have an excellent fishing partner that is welcome places and so far it's falling into place.
I usually drop em in the grass and then fish out another cast or two while I wait for them to get tired enough to hold still - that way you can actually tell how long they are against the rod. - JT
