After your dog is diagnosed, you’ll need to choose between pills, chewables, and topical flea treatments. They all have pros and cons, which you can discuss directly with your vet. Topical flea treatment for dogs: Topical flea treatment for dogs includes shampoos, powders, and spot treatments. Some are more effective than others, with spot  treatments being the most effective topical flea treatments for dogs because they eliminate fleas, larvae, and eggs and protect your pet for around 30 days. Oral flea treatment for dogs: Oral flea treatments for dogs can come in pill or chewable forms. Which is best for your dog depends on which they’re more likely to eat. Some dogs prefer chewable forms that are flavored and resemble their other treats. Oral flea and tick prevention for dogs is the most successful in eliminating and preventing fleas, but the best ones require a prescription from your vet. After you give your pet oral dog flea treatment, they’ll be protected for thirty days. Flea collars: Another option is flea collars which can prevent parasites by using chemicals released into the dog’s skin. Flea collars are worn around the neck and can be useful when you need more time to eliminate fleas from around your home. However, they can also be dangerous because some cause GI issues and skin irritation.
