🐾 How Do Dogs Get Fleas?

Fleas can jump over 100 times their body length. That means even if your dog only goes outside for short potty breaks, they’re still at risk. Dogs can pick up fleas from:

Tall grass or leaf piles
Other animals (wildlife, other pets, stray cats)
Dog parks, groomers, or kennels
Even your home’s entryways or shoes

Let’s break down the signs, solutions, and smart ways to keep your dog flea-free all year long.

🔍 Signs Your Dog Has Fleas

Not sure what to look for? Keep an eye out for:

Frequent scratching, biting, or licking
Red bumps or hot spots
Hair loss, especially near the base of the tail
Black specks in the fur (that’s flea dirt, aka flea poop)
Restlessness or discomfort
Tiny fleas crawling on their belly or inner thighs

🚿 What To Do If Your Dog Has Fleas

Step 1: Treat Your Dog Immediately

Use a flea shampoo or fast-acting oral flea medication recommended by your vet.
Don’t forget a flea comb to physically remove fleas and eggs.

Step 2: Clean Your Home Thoroughly

Wash all bedding, blankets, and rugs your dog has touched.
Vacuum carpets, floors, and upholstery daily for at least a week.
Use a home-safe flea spray or call in pest control for severe infestations.

Step 3: Treat All Pets in the Household

Even if only one dog seems affected, fleas spread quickly. Treat every pet in the home to prevent reinfestation.

✅ Preventing Fleas: The Smart Way

Prevention is so much easier than fighting an infestation. Here’s how to stay ahead:

- Monthly flea preventatives (topical or oral)
- Flea collars for added defense
- Regular grooming and flea checks, especially after outdoor adventures
- Keep lawns trimmed and avoid letting dogs play in dense brush
- Consider year-round flea control, even in cooler climates—fleas can survive indoors.

🌿 Natural Remedies: Do They Work?

Some pet parents prefer natural options like apple cider vinegar sprays, essential oil blends, or diatomaceous earth. These may help repel fleas, but they aren’t always strong enough to treat active infestations. Use them as a supplement, not your primary defense—and always check with your vet first.
