Q: How do I choose the correct e-collar for my dog?
A: Masbrill has a range of models accommodating various needs as shown in the picture below. If you have any questions, reach out to us at Masbrillofficial@gmail.com for assistance.

Masbrill Model Range:


Q: Are e-collars safe for dogs?

A: Yes, e-collars are safe for dogs if they are used as the user manual recommends. Masbrill e-collars are intended to be used for short training sessions (up to 15 minutes per session) that require constant human interaction and supervision. They are not intended to be worn constantly. The total amount of time that an e-collar can be worn by a dog is 4 hours. Note that the electrical output of a collar is not strong enough to generate heat that can burn the skin. Additionally, a shock can only be delivered for 10 seconds at a time. After that, even if the button is pressed, the remote will time out, and no stimulation will be sent. If there is any lesion or marking after using the collar, this is caused by friction or pressure necrosis, not from actual “burns.” This only occurs during inappropriate wear. For more information, please see our collection of dog training devices.

Q: What is a barking collar?

A: A barking collar (also known as a smart collar) is an electronic collar that is triggered by the dog's barking and has no remote control. MASBRILL has two different bark collars: a regular model with tone, vibration and shock functions, and a shockless one. See this page for details. For more information, please see our collection of bark collars.

Q: If I buy two systems, will they interfere with each other?

A: No, the collar receiver gets the commands only from the remote it is synced with. CAN I CUT THE STRAP TO ADJUST THE LENGTH OF MY COLLAR? Yes, you can cut the collar strap to the desired length using sharp scissors. Remember to measure your dog's neck carefully before trimming the collar.

Q: For how long does the battery last on one charge?

A: That depends on the intensity of your training sessions. The time may vary from one day to one week.

Q: How can I choose between the two sets of contact points?

A: We recommend picking shorter contact points for short hair and longer contact points for longer and thicker hair.

Q: Do I need to use the silicone covers?

A: Yes, they must cover contact points at all times since they help prevent skin irritation. But remember that silicone caps will help avoid irritation only if the collar is used as recommended by the user manual. This includes the following instructions:

  1. Use the collar for short training sessions (up to 15 minutes) under the supervision of an adult.
  2. Make sure the dog wears the collar for no longer than 4 hours a day.
  3. Regularly reposition the collar on the dog’s neck and make sure the dog’s skin is clean and irritation-free.

Q: How can I know when to charge the batteries of the dog training collar?

A: For the remote transmitter: the symbol will show up on the right downside of the LCD screen. For the receiver collar: if you hear 10 seconds beep, you have to charge it

Q: Any other better training methods?

A: You can prepare some dog food as a training incentive to achieve better training outcomes.
Each time you restrain your dog’s misbehavior, you can tell her what can do and what is not. after several repetitions, your dog understands what you like and what you don't like.

Q: How long will it take to get my dog can train well?

A: It takes time to eliminate for my dog toch an obedience command. Please be patient. Over-quick training may not lead to ideal outcomes.

Q: How do I charge the system?

A: You can use the charger (included in the package) to charge the system using your wall socket. Depending on the model, the charging time may vary from 2 to 4 hours.

Alternatively, you can charge the system using the USB port of your computer, but it may take more time.

Remember to charge the system even if you are not using the system. Otherwise, the batteries may deteriorate quickly.

Q: Can I replace the batteries?

A: The batteries in Masbrill e-collars are non-replaceable. Depending on the frequency of use, they are intended to last between 1 and 3 years.

Q: Is the collar waterproof?

A: Masbrill collars are water-resistant. This means that your dog can safely jump into a puddle or run in the rain, but we do not recommend using these collars for underwater training or swimming. If the collar comes in contact with salt water, we recommend rinsing it with tap water before wiping it or leaving it to air dry. The remote transmitter is not water-resistant.

Q: What is the maximum operating range of your collars?

A: Depending on the model, the range may vary from 330 to 860 yards. Please refer to the model overview table or your user manual.

The range may also vary depending on terrain, buildings, trees, and electromagnetic interference from other devices.

Q: How do I choose the right stimulation level?

A: Every dog has their own recognition level. Even a slight change in your dog’s behavior, such as looking around in curiosity, scratching at their collar, or flicking their ears may indicate that they feel stimulation. If your dog does not have a visible reaction (like twitching their ears or head), the level you selected may be too low. Increase the level by 1 and test the stimulation. Repeat until the dog starts reacting.

WARNING: If the dog yelps or becomes agitated after you deliver stimulation, the level is too high for your pet.

Q: For how long can I deliver static shock or vibration to my dog?

A: You will be able to deliver vibration or static shock to your dog continuously for up to 10 seconds. After 10 seconds, the remote transmitter will time out. The vibration or shock button must be released and pressed again to proceed. It is highly recommended to limit the continuous shock delivery to no more than 3 seconds (the smaller the dog, the shorter it should be).

Q: My dog doesn't respond to the shock stimulation mode.

A: First, test the shock function by bringing the collar’s prongs in contact with the test bulb. If the test bulb lights up, do the following:

  1. Make sure the collar fits snugly and the contact points touch the dog’s skin. Both contact points must be touching the dog's skin for your dog to feel stimulation.
  2. If your dog has a long or very thick coat, trim their hair where the collar contact points normally touch the skin.

If the above suggestions do not resolve the issue, please reach out to our support team at Masbrillofficial@gmail.com.

Q: The collar is too big for my dog’s neck, can I cut it?

A: You can definitely trim the collar to minimize excess for a better fit. However, make sure that the collar is functioning properly and that your pup is responding as we will be unable to accept any returns/exchanges or offer replacements on altered products. We suggest looping and tying the excess collar material during the trial period. (You may contact support regarding the suggested method for this.) 
Over time nylon can start to show wear and tear. To help prevent fraying or a loose string, one trick is to use a lighter. Quickly run a flame from the lighter over the edge of your collar. Move the flame quickly to avoid leaving burn marks on your collar. Again, make sure that the collar is functioning properly and that your pup is responding as we will be unable to accept any returns/exchanges or offer replacements on altered products.

Q: The collar works intermittently.

A: There may be three possible explanations:

  1. There is a circuit delay. The stimulation button must be held down for at least 1 full second for the transmitter to have enough time to send a signal.
  2. The collar is in sleep mode. The collar receiver enters sleep mode after 5 minutes without motion. To wake it up, you need to press any button on the remote twice or shake it (depending on the version of the receiver).
  3. Low battery. Fully charge the collar and the remote, re-sync them if necessary, and try again.

Q: The collar or the remote doesn’t charge.

A: Try charging the device with the USB port of your computer. If this helps, it means the wall adapter will need to be replaced. Reach out to our support team at Masbrillofficial@gmail.com for further assistance.

Q: The collar does not respond to the remote.

  1. Make sure the collar and the remote are both fully charged
  2. Make sure the system is synced. For instructions, please refer to the user manual

If the steps above do not resolve the problem, reach out to our support team at Masbrillofficial@gmail.com for further assistance.

Q: Can I order spare parts for my system?

A: Yes, most parts can be ordered separately. Please find them on the Replacement parts page.

Q: Can I order a second remote and pair two remotes with the system?

A: No, you cannot use two remotes to control one or multiple collars, but you can use one remote to control multiple collars.
