We haven't seen any indication that dogs are affected by coat thickness or fur length when using the Halo Collar. While we have not specifically tested the Halo Collar on LGDs as a focus group, we have successfully tested the Halo Collar on a wide variety of dogs with a range of temperaments.

Rather than efficacy being determined by the size or breed of the dog, each dog's individual tenacity, drive, temperament, and energy level is unique and determines what level of diversion they need when presented with a distraction. For many dogs who are highly-focused working dogs, the most important part of the process will be the training. Cesar's step-by-step instructions in the app will provide the thorough guidance you'll need to work with your dog's instincts and help curb the desire to be an escape artist through positive associations (as well as boundary awareness). The Halo Collar's feedback is never intended to be punitive, so the most important part of the process is to teach your dog to recognize the prompt that helps them remember that it's time to turn around.  This process was designed to work with highly-driven dogs as well as sensitive ones, and the most important part is to teach your dogs what the communication means.

We have not seen any reason to believe that the Halo Collar is prone to inducing higher rates of sensitivity than other collars. Our experts have advised that it's best to accommodate the widest range of dogs when providing recommendations, and we always err on the side of caution and safety as a general rule.

It is possible to keep the Halo Collar on day and night, as long as your dog remains comfortable, and you rotate it on your dog frequently. The Halo Collar requires approximately 2 hours to fully recharge, or you can swap the collar out for another one. Some working breed dogs with less-sensitive skin are able to continue wearing an e-collar continuously. However, we do strongly advise removing the Halo Collar to prevent the risk of irritation.

If you choose to keep the Halo Collar on your dog overnight in addition to throughout the day, please make sure to reposition the collar frequently, and to check that the fit is correct throughout that time. This includes before and after exercise--that way, you can check to make sure that the collar is not too tight after bloodflow increases, or too loose beforehand. A snug fit is the goal, with the ability to fit two fingers under the strap without being able to wiggle or rotate the collar too freely.
