Read the exact package before fitting

Before putting on any flea collar, read the package for the intended species, minimum age, size range, wear instructions, precautions, and storage directions. The DEWEL product page describes an adjustable 63.5 cm collar for medium and large dogs. Use the label on the specific product in hand for the final directions; similar-looking collars can have different instructions.

If your dog is very young, pregnant, nursing, unwell, has sensitive skin, or uses another parasite product, contact your veterinarian before starting. Do not combine treatments or change a schedule based on a blog post or product title alone. Keep the package so the ingredients and instructions remain available.

Check fit and hardware without guessing

Follow the package’s fit directions and confirm the collar fastens securely. Inspect it for damage, residue, or a rough edge before use. If the label gives a specific amount of space or trimming method, follow that direction exactly rather than relying on a general rule from another collar.

Do not attach a leash to a flea collar unless its own instructions say it is designed for that purpose. Fit the dog’s walking harness separately, and check that the harness does not pull, twist, or cover the collar in a way the label advises against.

Introduce it during a calm period

Choose a time when you can observe your dog and are not rushing to leave home. Put the collar on according to its instructions, then watch how your dog behaves. Avoid introducing several new grooming or parasite products at once, so you can identify what may have caused a change.

Check the neck and nearby skin as directed on the label. If you notice irritation, swelling, unusual behavior, or another concerning change, follow the package’s instructions and contact a veterinarian promptly. Remove the collar only as directed by the label or a veterinary professional.

Plan around bathing, swimming, and other products

Before bathing, swimming, or prolonged outdoor activity, check the collar’s specific water instructions. Product descriptions may use broad language, but the package is the source for the conditions that apply to the item you purchased. Ask a veterinarian before adding another flea or tick treatment.

Keep a note of the date the collar was fitted and the replacement timing stated on its label. Do not assume protection lasts for a particular number of months if the package for your specific collar says something different or if it has been damaged.

Store and dispose of packaging carefully

Keep unused collars in their original packaging, away from food, children, and animals. Follow the printed temperature and storage directions, and do not leave the product in a hot car or damp bag. Keep the label or take a photo of it so instructions can be checked while travelling.

Dispose of packaging and any removed collar according to the label and local rules. Wash your hands after handling if the package says to do so. If your dog has a reaction or you are unsure whether the collar is suitable, ask a veterinarian before using it again.
