Will this work on a larger dog?

We've used this system for three Golden Retrievers and it's worked perfectly for all of them. Just follow the instructions when training them. All three of our dogs learned after only being shocked 2-3 times. They get a warning audio chirp when they approach the fence line. When trained properly they quickly learn to stop when the get close enough to get the "chirp" warning. The battery in the collar should be replaced every four months on average.BTW - You need to buy the SD2000 system (about $97). The collar won't work without the system. The system comes with one collar. We've used this system for three Golden Retrievers and it's worked perfectly for all of them. Just follow the instructions when training them.

It works well on our 70-80 lb. Lab and Labradoodle mix. My sister used it on her 90 lb. Great Dane. All were properly introduced to the system and all boundaries were flagged.

It's not the size of the collar but the training that should be done. Yes, it works on a larger dog but only if you train them properly. Some learn with the first vibration but others learn to run through and you can never get them back so follow the instructions to train them properly.

Yes. I have a Havanese and he's 20 lbs and it works for him. Hope this helps.

Yes. I actually bought mine for use on both me and my Chihuahua. There is some vibration and the noise frightens him, but your dog may be fine with it since he's bigger. It works really well.

The largest size is a Large and it barely works for my 140 pound Rotti, but it is the absolutely best device I have found for lifting my big dog. I have tried other items and because my dog does not have a tail they just slip off the end. This one is streched as far as it will go and it works! Be sure to line the back legs with thick fuzzy socks or sheepskin to protect your dog. The back harness will dig in and hurt your dog without added layers. Good luck.

definitely! it's VERY long. It's made to fit any size dog, but is adjustable.

My dog isn't that big.. But if u buy the large size. It's adjustable. I'm sure it.would work. No special collar is needed either

My largest dog is 17 pounds and there is still room with him on it. So, I would think it would work.

My guess is that yea it would work. It is somewhat flexible...depending on size of pup.

yes. It works great for large dogs. One zap and they wont come at you again. It doesnt seem to harm them, just freaks them out.

I have had great success, my puppy is 30 pounds and since you can adjust the degree of stimulation (I use #3) you should be able to use it on a dog as large as 160 pounds, maybe more, it packs a punch, I tried it on my thigh and wow

It should work for any size--you have to buy the halter/harness it attaches to separately. That's where the size differential would come in. I haven't tried it with two dogs at the same time--there's only one extension with the Zip that attaches to the harness. If you are going to try two dogs simultaneously, I would suggest calling the company and finding out if they sell the additional extension line.

I think this would work fine for a large dog. My dog tried to use it but his tongue was too weak (but he's just a little 12 pound dog). I don't think it's hard for the dogs to figure it out as long as their first few attempts are successful.

I had a large, it worked great. My golden retriever got along great with the help it gave him. Please don't leave it on him all the time as it started to rub on him and he got an sores where the harness rubbed underneath him.

I bought this for 2 35 lb schnauzers. Not sure how well it would work for larger dogs.

I use the device on a English Bulldog. I think it would work fine on any dog that size or larger. I don't think weight would make a difference.

I have a 180lb 11 month old Great Dane and we had to buy a larger collar in order to use it. It ALMOST fit around his neck so I'd say it would work for most dogs but you can use it on another (nylon) collar if the one it comes with doesn't fit. I hope this helps!
