I have two medium size mutts. Chase is laid back but loves to run and play and Rufus is a very timid and scared of alot. First off let me say this make sure the range is adjusted on the box before putting the batteries in the collars. My husband was holding the collar in his hand inside the house (far away from the lines) and got shocked on the 5th level! Ouch! We readjusted the range to two feet from the line and truned the collar down to level 2 after that.I think the range came out of the box set on 40 feet I took chase out on a leash and let him lead me to the perimiter rather than me taking him over there and tossing a toy or treat across the line like youre instructed too. It only took him 2 times of trying to cross over the fence before he realized that he didnt wanna go anywhere near those flags. He LOVES playing fetch but you better believe if that ball goes NEAR that fence he will NOT even try to go get it! We did have one incident the other day where there was a cat in the back yard and Chase blew through the fence and did not even flench when he was getting shocked! However, ever since then he has been even more reluctant to get close to the fence so I think the level 5 shock hurt him enough that he wont be doing that again (The shock level increases as they cross the perimeter). Rufus was a different story. I let him lead me to the perimeter just as I did for Chase and once he got shocked he was terrified of his yard. We would lead him around and show him all the places he could go but he would never leave our side. When we would let him out by himself he would not even leave the back porch. We tried for 2 weeks to get him used to it but he never did. I called the company for advice and they instructed me to start over. Here is what the customer service rep informed me to do incase anyone else has this problem. Give him a week or so to get used to being in his yard without the collar on. I put Rufus back on the runner we were using before we installed the fence. After he is comfortable in the yard again put the collar on but dont put batteries in it. After a few days of doing that turn the vibrate only function on and see how he does with that. Once he is comfortable wandering around the yard you can turn the shock back on to the lowest level to correct him if he tries to leave the perimeter. Another issue we had is that if you lay the line within 3 feet of any wire (telephone,cable,electric,etc) the signal can apparently transmit to that wire and mess up your range. We noticed that sometimes when we would let the dogs out the back door their collars would vibrate like they were nearing the edge of the perimeter. The back door is in almost the very center of the perimeter so we couldn't figure out why this was happening. The customer service rep told us we would need to dig up and move the line further away from the house so this wouldnt happen anymore. One more thing- I apparently misread some information about this fence because I thought the collars continued to shock the dogs when they were outside of the perimeter until they got back inside of it. That is not true though. The collar only shocks them when they are inside of the range you set. So if you set a 2 foot range it will shock them 2 feet before the line and 2 feet behind the line. Once they get out of that zone it will deliver the static charge. Im sorry this was so long but I understand what a big decision it is so I thought I would give you all the details. Overall I love this fence and have alot of trust in it and my dogs response to it. I would definetly recommend it to anyone looking at this as an option. I hope this was helpful!
