Yes, many veterinarians do recommend flea and tick collars like the DEWEL PRO flea collar for their patients. These collars are designed to prevent flea and tick infestations and can be a convenient and effective solution for many pets. However, it's important to remember that not all flea collars are created equal, and some may be more effective than others. It's always a good idea to consult with your veterinarian before starting any flea or tick prevention program to determine the best options for your pet's needs. Additionally, it's important to follow the manufacturer's instructions carefully and to monitor your pet for any signs of irritation or adverse reactions to the collar.
