Small dogs have big voices, and they deserve tech that's tailored to their size. NanoBark 2.0 bark collar is purpose built for dogs with neck sizes 4 to 15 inches and helps stop nuisance barking so you can enjoy a peaceful home together. The slim, low-profile bark collar features a snug new fit with an updated design for extra flex and durability. Delivering the minimum effective level of correction for max results, it only responds to your dog's unique voice and tunes out the neighborhood noise. With 10 levels of auto-adjusting static correction, the bark collar helps prevent your dog from growing desensitized with patented Variable Pulse technology. The long-lasting battery stays charged for up to 7 days and the waterproof design means you can enjoy puddle play with ease.Proper fit of the collar is important. A collar worn for too long or made too tight on the pet's neck may cause skin damage ranging from redness to pressure ulcers. This condition is commonly known as bed sores. Avoid leaving the collar on a pet for more than 12 hours per day. When possible reposition the collar on the pet's neck every 1 to 2 hours. Regularly recheck the fit to prevent excessive pressure; follow the instructions in this manual. You may need to trim the hair in the area of the contact points. However, never shave the dog's neck; this may lead to a rash or infection. Never connect a leash to a collar with contact points. It will cause excessive pressure on the contact points. When connecting a leash to a separate collar, do not allow it to put pressure on the collar. Wash the dog's neck area and the contact points of the collar weekly with a damp cloth. Examine the contact area daily for signs of a rash or a sore. If a rash or sore is found, discontinue using this product until the skin has healed. If the condition persists beyond 48 hours, see your veterinarian. For additional information on bed sores and pressure necrosis, please visit our website. This product is only for use with healthy pets. If you're not certain that your pet is in good health, we recommend that you take your pet to a veterinarian before using this product. DO NOT attach a lead to the training collar. Not for use with aggressive dogs. Follow all safety instructions in the product manual.

My little dog likes to yap a lot. This definitely helped stop most of the barking. It fits well, is easy to put on and charge. It doesn’t hurt your dog, it’s just a vibration, which I like.

Bark collar
7 months ago
Pet safe nano bark 2.0 bark collar for small dogs works well because when they bark it feels a little vibration. It’s meant for small dogs. The design and fit is nice because it’s a thin collar. It’s easy to adjust to fit to your pup.

I was worried it wouldnt fit my miniature schnauzer because it can be difficult finding just the right fit but this collar was the perfect size. It wasn't too snug and my dog didnt seem bothered by the material or mechanism. I did notice some lessening of the barking so I would say it was a win!

7 months ago
I really wanted to love this product, but unfortunately it doesn’t work consistently for my 20 lb maltipoo. He still barks with this on. I do like how small and lightweight it is. It is very easy to charge, as well. There wasn’t really any setup and seems safe for use. I really wish it worked better. Maybe there’s a setting or button I am missing?

We're sorry to hear your maltipoo is not yet responding to this collar! As each dog is an individual they do all respond differently to different types of correction, so it's possible static may not be the best fit for your dog's personality. It is also possible, however, that he may not be consistently feeling the correction, or there may be another reason he's not responding. So that we can troubleshoot with you and find the likely root cause and best possible solutions, please reach out to our live support team here-

Small, but mighty bark collar!
7 months ago
This collar is marketed for small dogs, but it fits and works beautifully for my medium sized American Foxhound! It is so easy to use and adjust! I am excited that I have found a great collar that’s able to correct while not being too heavy and bulky like other brands! Definitely a must try for anyone needing a good bark collar!

Great deterrent
7 months ago
Our pup has started to get more vocal in her old age, and this product has really helped decrease her barking. She’s very smart and learned quickly. At this point we don’t even need to put the collar on her … just shoeing it to her or placing it near her is enough of a deterrent and keeps her quiet! It fits true to size and seems rather durable … no issues after a few months of use.

Works great!
7 months ago
I live in an apartment with very thin walls. My shihtzu tends to bark and growl whenever he hears someone by the door. This collar has been handy on the days where I have had to work from home and can’t have him barking while talking to clients. My dog learned very quickly to stop barking when the collar was on. My dog is 7lbs and the collar fits well. Battery seems to last long but I also don’t keep it on him all day long. The collar is also low profile and doesn’t bother my dog.

Almost Fit
7 months ago
The instructions for this product are very easy to follow. The setup is not difficult. The fit however was off, as this did not fit my dog. I consider her a small dog. I adjusted the collar as large as it could go and it was almost able to fit her, if I had another quarter inch.

Effective Bark Control
7 months ago
This collar is easy to operate and is an effective way to control barking in a small dog. I was afraid it would hurt my dog when it zapped her. It surprised her, but didn’t hurt her so that made me feel better about using the collar. It only took a couple of days wearing the collar before her annoying barking was under control.

We're sorry to hear this collar was not the right fit for your dog, and that your sister's dog has not yet responded!
This collar is recommended for dogs with necks between 4-15"; if your dog's neck is larger than 15", a different style of collar would be a better fit.

Comfortable

Its lightweight, comfortable, and effective for small dogs, with users praising its automatic adjustment of 10 static levels and long battery life, though some report occasional false corrections from other noises, despite its design to avoid them.

Thank you for sharing these concerns with us! As this collar is designed to respond specifically to barking, activations from other sources would be very rare when the collar is fit and used as intended. We do recommend ensuring the collar is fit snug enough to fit one finger underneath, and with the box on the collar situated high on your dog's neck directly under their chin. Additionally, it is important to ensure your dog is only wearing the collar at times when obsessive barking is likely to occur, and that it's removed during sleep, when playing, etc.
If you have any questions about training with this collar or are experiencing any difficulty with your own collar, please don't hesitate to reach out to us. Our live support team can be reached here-

Thank you for taking the time to share this feedback! We're glad to hear your dog has been comfortable wearing this collar, and is responding well to training.
In case this information is helpful, for the collar to consistently detect barking we would recommend adjusting the box on the collar so that it is as high on your dog's neck as possible and directly under their chin; this will place it over the vocal cords for consistent bark detection. If you have any questions while working with your dog, please don't hesitate to reach out to us here-

Excuse the sleepy dog photo but we love this collar for our little yappy dog. It is much smaller than another collar that we have and is more comfortable for our pup. When he is wearing it, he stays quiet especially when the deer walk past our window…works great for a small dog!

The collar was easy to set up and put on. Our dog seemed comfortable wearing it and even seemed to want it back on after we took it off. Lightweight and seemed effective quickly. Our dog doesn’t bark a ton anyhow, but she had shorter bursts when she saw dogs across the street.

Great size, adjustable and it works!
8 months ago
I'm very happy with my PetSafe NamoBark 2.0. When I first got the collar I was able to adjust it easily to fit my baby Penny. As the instructions read I made sure I was close by when she first wore it to see her reactions. She is a very verbal girl when our neighbors let their pets out and when someone walks by our yard. When she is wearing this collar her yappy barking stopped. Now when we go out and I put it on her she now behaves. Alot more comfortable and not as bulky as her correction collar we had gotten for her previously.

This collar fits well and works to reduce my dogs barking through out the day. The clips and snaps were pretty secure and the collar didnt not fall off or come lose while my dog was outside in the yard. The collar seemed pretty accurate in detecting when my dog was barking. I plan to buy another collar for my larger dig since this one worked so well!

Lightweight, comfortable, and effective
8 months ago
My dog doesn't mind wearing the collar. It is lightweight and seems to be comfortable for her. It only took 2-3 days of use to positively impact my dog's barking. I've gotten into the habit of charging it regularly like I do my other electronics and so far the battery has held a charge without issue. It has randomly shocked my dog, but not often. Overall I'd say this is a good effective barking collar.

This Petsafe nanobark 2.0 Bark Collar for small dogs works well. Easy to assemble and fast to charge. It’s a good fit for small dogs and easy to adjust. Good size for smaller dogs. The materials it is made with make it seem to heavy for my little dog so I wasn’t impressed with the weight of it so I gave it three stars.

I tried the PetSafe NanoBark 2.0 bark color for small dogs with my yappie little shitzu. It fits well and is the perfect size for small breeds. You can adjust it to fit as snug as you need. We have frequent bike riders and cars that pass by and now I don't have to worry about my little guy disturbing the neighbors for a night time turn out. It comes with a usb plug in to charge it up. The battery lasts a long time even though I haven't ran it out because I just charge when it's not being used for turn outs.
