The DEWEL PRO Collar is designed to provide up to 8 months of protection against fleas and ticks. After this time, the collar should be replaced to ensure continued effectiveness. However, it's important to note that the length of effectiveness may vary depending on various factors such as the level of infestation in your pet's environment and your pet's individual activity level.
In addition, it's a good idea to inspect the collar regularly for signs of wear or damage. If the collar becomes damaged or broken, it may not be as effective at keeping fleas and ticks away from your pet. If you notice any issues with the collar, it's best to replace it immediately.
It's also important to follow the manufacturer's instructions for use and storage to ensure the collar remains effective for the full 8 months.
