20 Jul How Do Dogs Get Fleas?
The sky is blue … water is wet … and fleas love dogs! Why do fleas love our pets so much? The warmth of their bodies, the deep lush fur for hiding and egg-laying, and the plentiful opportunity for meals make dogs and cats the ideal host for those pesky external parasites.
Where Do Fleas Come From?
Fleas are naturally found in the outdoor environment, especially areas that boast humid, temperate, and shady climates (I’m looking at you Florida, the southern and gulf coast states, and you too California!). Even if you don’t live in one of these flea hotspots, you’re not off the hook! Fleas can thrive virtually everywhere — including indoors. Beachgoers, dog park aficionados, and road-tripping pets frolicking in environments all over the country are especially at risk for bringing them back home, but that’s not all of the ugly truth. While fleas thrive and perpetuate on wild and outdoor animals and in locations where animals congregate, they can also hitch a ride on our pets during outdoor jaunts. Fleas are — wait for it — quite “smart,” and have even adapted to find their way indoors via humans, as we bring their tiny eggs inside on our shoes, clothing, and personal items. Fleas and skin problems resulting from fleas are so common that veterinarians will often incorporate the question, “is your dog on a monthly prescription-strength flea control product currently?” for every dog that is itchy or is being assessed for skin problems.
Does My Pet Need Flea Protection?
Our veterinarians are constantly fielding questions – and addressing some common misconceptions – about fleas …
My dog stays primarily indoors so he does not need flea prevention, is this true?
My dogs are on flea prevention monthly but my indoor cats don’t need it because they never go outdoors, right?
Aren’t fleas only a problem in the warmer summer months?
I don’t SEE fleas on my dog so this cannot be a flea problem, correct?
First things first, if your dog is a dog, and your cat is a cat, fleas have their feelers out for them! Fleas have devised some sort of incredible evolutionary-arthropod-intelligence to perpetuate their species and seek out your pet’s fur, whether they live entirely indoors, or just step out onto the balcony for a grass patch potty break (which, I might add, we do encourage taking your pup for multiple daily outdoor walks in the environment for their mental and physical well-being!). Our veterinarians recommend that ALL PETS in the household (indoor cats included) be given a prescription-strength flea control all year long, as recommended by your family veterinarian and based on your local flea behavior.
We established earlier that fleas tend to thrive in warmer, more humid temperatures and that flea allergies tend to flare during the summer months. However, your veterinarians see the fallout from fleas all year long — especially since fleas can create a perfect thriving life cycle inside your home too, no matter what the weather is outdoors! Yes, that is right: fleas share our love for 75-degree environments, and once they find their way inside your home and feed on your pets, one female flea can produce 50+ eggs per day! With the complete flea life cycle from egg to adult-only taking about 3 weeks in its entirety, you can imagine how quickly your home’s flea population can explode into a full-fledged flea infestation!
Evidence of Fleas
So now this brings us to the question: How do I know if my dog has fleas? Another concept that seems to surprise Pet Parents is that just because you don’t SEE fleas, does not mean they are not there, wreaking havoc on your dog’s skin and coat! WHAT!? Yes!!! Fleas are small, clever, and FAST! Dogs are even faster at locating them, chewing them off, and destroying the evidence. A flea allergy in dogs (a severe allergic reaction to the protein in flea saliva) causes them to be even faster at ridding their body of fleas due to the intense skin reaction that they are feeling from even just one flea bite.
Veterinarians are well trained in looking for the clues that fleas leave behind; namely examining the patterns of hair loss and irritation on a dog’s coat and skin, evaluating the areas where your dog is itching most, finding sneaky fleas with our magical flea combs, and identifying tapeworms in a fecal sample (the result of fleas swallowed by an infested dog). In combination with all of these signs, the biggest hint of all is the usage or absence of monthly prescription-strength flea prevention! So, if you’re looking for how to get rid of fleas on dogs, the first step is a flea prevention medication.
