Not the best collar for a 9 month old Lab

Not the best collar for a 9 month old Lab...The quality was ok but I think this collar is better suited for medium to small dogs.

We checked on several of these training collars and this one was recommended over and over so we got one. Sometimes it doesnt even get his attention and other times it seems to work well. Maybe we just need more time to make some adjustments. We do have a Husky and there coat is very thick, that may be part of the issue.

Collar is very wide and will not comfortably fit on small animals

i started the puppy (7 mo)trying the shock collar. it was awful. the dog squeeled & the thing went off & kept shocking her everytime she squeeled. wouldnt stop. just kept going off randomly. removed it immediately. so i tried the citronella collar. seems to work alright for now. however i have 2 other dogs that do quite a bit of sounding off.(9 yr & 4 yrs) so i decided to get them one each as well. one is intimidated & won't come out of his crate. (9yr)the other one has been shaking all morning as if he was an abused dog.(4 yrs) i took it off the one shaking as he is a very sweet dog & only follows the barking if the other one starts it. so i have left it on the one that won't come out of his crate. i assume he will get used to it & realize what it is for since he is the one that always starts the barking.(9yrs) over all i don't like any of them as they seem to go off randomly even if they are just giving themselves a shake. i will only use it until a day or 2 for them to get the idea what the purpose is. the puppy got it right away. the older dog is still trying to figure it out i think.

While there is nothing wrong with this collar per se, it didn't enable me to do what I had hoped which was to get my dogs to heel without the stress caused by choker snap chain collars. I have a particularly stubborn 9 month pup that just will not heel.

I bought this last summer from an outlet store.
Seemed safe and thought it would've been big enough for his adult size (he was 6 months old at the time). Unfortunately seems a bit snug now, and the end is fraying very badly..
Overall, good collar but it's already time to replace it.

I measured her current harness for my growing 5 month old beagle/ lab mix and this one shouldve been perfect.  Simply put, it was not.  She got out of it easily- twice, at a local park and the only reason she stayed safe is because she loves being around people.  Spoke with some people there with dogs and decided to go with a Puppia harness instead.  This one is just not secure enough.

After just a few months of use our dog can cross the line and not make the collar react. It takes notice of the dog being too close every now and then.

I don't doubt that this collar is effective for bigger dogs but I have a little pomeranian chihuahua and I don't know if she was just being overly sensitive, but she only wore it for 10mins. She saw another dog, growled, it vibrated, she kept growling, it vibrated again and then she persisted and it shocked her! She yelped and jumped and I had to lift her to calm her down. She was still whimpering so it shocked her again! I had to take it off and carry her home. I guess it was too strong for her. I've never put it back on her. Maybe she's just too small for the charge

This collar will not work for training as it can't be choked down to correct pulling, etc. Because it has a metal piece on it that blocks it. It's fine for trained dogs and looks nice.

For the length, you'd think it would be wider, but I love the collar. My lab used to slip out of all of her collars simply by pulling on the leash. She has yet to slip out of this one!

One of my Malchese has to wear a chain collar because he chews up other kinds. I was hoping he had grow out of that stage so  I bought a couple of these collars for my dogs. The chewer chewed his up soon after I put it on him. Otherwise it was an appropriate collar.

I have a full grown Australian Shepherd (over 50 lbs) and while this collar works great to get him to not pull, but its very difficult to put on or take off.  The weight or thickness of the links is just too much to be able to easily squeeze to remove the collar.  Plus, an 18" collar is really larger than 18" and I had to remove like 4 links leaving half the circumference for prongs and the other half for the chain.  I went to the store and bought a small off brand one which is much lighter and easier to take on and off and it was 'just right' for a full grown Aussie.  I didn't have to take out any links.  The ends of the links were just as rounded (not sharp) etc.  I would say this medium might be right for a full grown large german shepherd (I imagine).  or a big Lab.

Doesnt breakaway like other breakaway collars.  Had to replace another brands breakaway collar after our puppy broke it off out cat and chewed it up.  This one done not breakaway as easily as our puppy has been tugging on it while the cat still had it one.  I would recommend a different brand.  Bell was a nice feature until it was crashed by the puppy.  If the breakaway part of the collar is not a concern this is a good collar.

Collar snags and unravels but the rest works great

I have a big lab.  She responds well to these pinch type or gripping collars. This is a very good quality collar. My dog  responds well to it.  She is very aware that the collar is on her.  Smaller pinch collars tend not to make an impression.

I don't see the need for the weight added by the quick release as these colars should not be tight on the dog. It looks like it will last forever, but it is so heavy that it hangs below her neck, when I would prefer the clasp and leash ring to stay at the back of her neck. (the picture of the one I purchased was not accurate.  It did not show the release clip.  Perhaps it is a picture of an older version) I always just slip it over her head rather than mess with the release. I also feel that I need to take it off of her when I am not walking her because it seems too much for her to lug around. It is probably for the best, though as it is safer for the dog.
