As a pet owner, it’s our responsibility to protect our dog from fleas.
Just yesterday I talking with my veterinarian, and he shared some information that I think every dog owner needs to hear. One of the biggest misconceptions is that if you don’t see fleas, your dog doesn’t have them. Unfortunately, that’s not always true.
An untreated dog can carry fleas into your home, your yard, dog parks, boarding facilities, grooming salons, training classes, and even veterinary clinics before an owner ever notices a problem. By the time you actually see fleas crawling on your dog, the infestation is often already well established.
What many people don’t realize is that adult fleas only make up a small percentage of the flea population. Eggs, larvae, and pupae can be hiding in carpets, furniture, bedding, cracks in flooring, vehicles, and outdoor environments. A single flea can lay dozens of eggs every day, and those eggs don’t stay on the dog. They fall off wherever the dog goes.
One thing my veterinarian explained that made a lot of sense is why you can have multiple dogs living in the same house and only one seems to have a flea problem. Many people assume that if one dog has fleas, every dog in the home should be covered in them. That’s not always the case.
Modern veterinarian-prescribed flea preventatives are designed to kill fleas when they bite the treated dog. Fleas may jump onto that dog, but they don’t survive long enough to establish a population. Meanwhile, an untreated dog becomes the perfect host. Fleas can feed, reproduce, and continue laying eggs without interruption. In many homes, the treated dogs appear flea-free while the untreated dog carries the burden of the infestation and continuously seeds the environment with new eggs.
This year has created nearly ideal conditions for fleas and ticks across many parts of the country. A mild winter followed by warm temperatures and increased humidity has allowed populations to survive and reproduce earlier and longer than normal. Veterinarians and pest professionals are already reporting heavier flea and tick activity than usual.
As a trainer, I see dogs from many different homes and environments. Fleas are not a sign that someone is dirty or doesn’t love their dog. Fleas are opportunistic parasites. They don’t care how nice your house is or how much you spent on your dog’s food. If they find a host, they move in.
The good news is that prevention is far easier, less expensive, and far less stressful than trying to eliminate a full-blown infestation. Talk with your veterinarian about a flea prevention program that fits your dog, your lifestyle, and your area.
Your dog depends on you to make those decisions for them.
Prevention isn’t just protecting your dog. It’s protecting every dog they come into contact with.
❗️❗️❗️NOTE: ❗️❗️❗️
Veterinarians and pest control professionals are warning pet owners that 2026 has created favorable conditions for both fleas and ticks. A relatively mild winter allowed more parasites to survive into spring, and the combination of warm temperatures, increased humidity, and abundant wildlife activity has accelerated breeding cycles. Fleas thrive in warm, moist environments, while ticks become more active as temperatures rise and host animals move through yards, parks, and wooded areas. Simply put, more parasites survived the winter, more are reproducing, and they are remaining active longer throughout the year. That means pet owners are likely to encounter higher flea and tick pressure in 2026 than they have in recent years.
