Have a look at our pictures of fleas and you won't need to ask yourself the question "what do fleas look like?" again.
These flea pictures will allow you to identify between the various types of fleas that may feed off your Chihuahua.
If your Chihuahua is constantly scratching, it is more than likely that fleas may be responsible for this. There are more than 2000 types of fleas across the world, with 200 of these types being found in the United States of America. The most common flea in the USA is the cat flea (Ctenocephalides felis), with the dog flea (Ctenocephalides canis) being commonly found in Europe.
The name cat flea would suggest that dogs in the USA would be relatively safe from fleas, where as dogs in Europe would be in trouble. Unfortunately this is not the case. Cat fleas are not fussy as to where their next meal will come from, and will just as happily feed off a cat, or a dog.
Humans can fall victim to fleas too, though primarily they will prefer to feed off your pets. In the event that you suffer from an infestation however, you can be guaranteed that you will also be bitten. This can be worrying since cat fleas have been known to carry the plague to humans.
Depending on the species, adult fleas will be between 1 – 2.5mm in length and brown in color, with a reddish tinge. When looking at a flea close up (you will only be able to do this in flea pictures), you will notice that body looks like it has been squeezed by two objects on either side of them, making them look tall and narrow from the front; this allows easier movement through fur. (You will see this in the pictures of fleas below.)
Fleas have no wings, relying instead on their legs which allow them to jump long distances to move from host to host and to change environments. They have six legs, with their two rear legs being designed for jumping.
Most of the time, the presence of fleas will be detected by reddened skin on your pet, finding flea dirt, and scratching and chewing of the coat, since they tend to be difficult to see.
If you find fleas on your pet, you can either treat it yourself or contact your vet to discuss the best possible treatment. It is important to note that if you have seen fleas on your pet, they will be living in your house and you should look into contacting professional pest control who will know how to kill fleas in your house and will deal with their extermination.

Note that cat fleas just as happily feed off a cat, or a dog.
Like the cat flea, the dog flea will not restrict itself to dogs, and will also feed off cats and humans.
This flea close up is of a dog flea. Note the powerful, long, rear legs which the flea uses to jump long distances.
Other fleas you may encounter are human fleas (Pulex Irritans). Human fleas are different to pet fleas, however, if your pet has been in contact with a person with human fleas, it may carry them in its fur.

Sand fleas can also present a problem, whether you take your dog to the beach or not since they feed off humans as well as pets.
Their bite can be worse than those of dog and cat fleas and can cause health problems such as Leishmaniasis, Carrions disease, Pappataci fever virus and Tungiasis.Sand fleas will burrow under the skin and will grow up to 200 times their normal size.
