Question from Tracey Newall
My dog dexter gets frontline flee treatment but recently he seems 2 scratch more i havent found anything but his skin flakey
Answer from Shanika Online Vet
It is good to hear that you are treating Dexter for fleas; fleas are definitely high up on the list of causes for an itchy dog. Dry flaky skin may well be as a result of scratching due to flea infestation but can also be affected by allergies and medical conditions.
It is really important to remember that a pet suffering from a flea allergy or irritation does not need to be full of fleas. All it takes is one flea to bite your pet to set off the allergic reaction cascade that leads to the skin being irritated.
What is a flea?
Ctenocephalides canis or felis (the dog and cat flea) are a small wingless parasitic insect that live on our pets and in the environment. Fleas can jump but they can’t fly, they need blood feeds to survive and a large proportion of the flea population are in the environment as oppose to on your pet.
Where are the fleas coming from?
Fleas live on animals as well as in the environment. The flea population consists of adult fleas, immature larval stages, dormant pupae and then eggs, as you move down the list the numbers increase significantly which is why we refer to them as a pyramid.
Fleas in the environment, by this we mean anywhere a pet with fleas has been, the warmth of our homes provides a great breeding ground for fleas in carpets, pet bedding and just about any nook and cranny.
Cats can also carry the fleas and they do not even have to be your own cats, for example if a cat comes through your home or garden then the fleas can jump off or deposit eggs as they go. This is why we often advise treating the home environment and in-contact animals also.
So how can you tell if your pet has fleas?
Gently part your pets fur and search through close to the skin, fleas are a reddish/brown colour and quickly move away from the light. It can be easier to find fleas on the underside of your pet as the coat is naturally thinner here. It is often easier to see the flea dirt in your pet’s coat than the actual fleas.
So what is flea dirt and how can you tell if there is any on your pet?
Flea dirt is the waste product produced by fleas and when dry it looks like little black specs, however if you wet it these black specs turn red as they contain digested blood. This brings us to the ‘wet paper test’, we comb through your pets coat and collect the debris onto a piece of wet white paper, if there is flea dirt present there will be small red dots visible where the flea dirt has dissolved in the water. The wet paper test helps to distinguish between flea dirt and just dried mud that may be on your pet’s coat.
Can the fleas live on humans?…………………….
