DO: Buy the Right Flea Collar for Your Dog’s Needs
If your dog is already suffering from fleas, buy a flea collar with strong insecticides that will kill fully developed fleas. If you are looking for a flea repellent, buy a gentler collar made with essential oils to prevent a possible flea infestation naturally. This will work well in warding off fleas but will be unsuccessful in eradicating those already present.
