Fleas are a problem for dogs and their owners alike. These tiny insects will live on the body of your dog, sucking the animal’s blood and laying eggs. The bites and presence of fleas will cause the dog to itch and if the dog happens to be allergic to fleas (the allergy is technically to the insects’ saliva) it can experience extreme itching, loss of fur in some places, inflammation, and infections. Regardless of whether the dog has an allergy to flea saliva, infestations must be dealt with or they will go on and on and the fleas will also infest your home, other pets, and can even live on humans. In short; you can be directly and adversely affected by an uncontrolled flea infestation.
Detecting Fleas
If you suspect that your dog has fleas because it’s been scratching more than usual, there are ways to check for their presence. Fleas are very small (about an eighth of an inch long), but visible to the naked eye, and brownish in color. Because they prefer dark places they will try to hide beneath the dog’s fur, under the collar
, or on the underbelly. Their fecal material can also be seen on the dog’s coat and looks like multiple black flecks or specks – almost like pepper. If fleas or their droppings are found it is time to treat your dog to get rid of them.
Treating Your Dog for Fleas
While flea collars, powders, and sprays may help to prevent infestations to some extent, they will not help if the dog is already infested. When fleas are infesting a dog the female lays eggs at a rate of about thirty per day. These eggs fall off the dog and into the carpet, soil, or wherever the dog may be. In these areas they hatch and pupate, eventually growing into adult fleas which can then re-infest the dog. In order to halt the cycle all the fleas on the dog and in the environment must be killed or the life cycle must be interrupted.
There are several flea treatments available for dogs, but one of the best is an oral medication that will not kill adult fleas, but does kill the eggs and larva. This interrupts the flea life cycle and prevents them from coming back, as long as the dog is not continually exposed to new fleas. If that is happening, the source must be cleaned of fleas whether it is the carpet, the environment, or other dogs with which your pet associates.
Fleas can be a real nuisance for dogs and their owners, but catching them and treating the dog quickly is the key to eliminating the infestation and preventing the insects’ return.

Leptospirosis is a bacterial infection that can affect a dog’s blood, liver, and kidneys. The bacteria that cause the illness are carried primarily by rats and other rodents, but dogs that are infected with the disease can infect other dogs as well. Ingestion of the urine of an infected animal is the most common means of transmission, but the bacteria can be contracted through damaged or thin skin as well.
Leptospirosis is an odd disease that can often show no signs or symptoms at all. In these cases the bacteria are eventually defeated by the dog’s natural defenses. Other times, and more often, however, the disease can be life threatening to the infected dog. The three main forms of the disease are hemorrhagic (infection in the blood, causing bleeding), renal (infecting the kidneys), and icteric (infecting the liver).
Hemorrhagic Leptospirosis tends to start with a high fever, loss of appetite, and general lethargy. Small hemorrhages start to occur in the mouth and eyes and the dog may develop extreme bloody vomiting and diarrhea. This form of the disease is often fatal.
Icteric Leptospirosis will often start the same way as the hemorrhagic form; with fever, lethargy, and loss of appetite. The mouth and whites of the eyes will take on a yellow appearance, similar to victims of jaundice. In some cases the dog’s skin may also appear yellow and jaundiced.
Renal Leptospirosis also starts with fever, appetite loss, and lethargic depression, but eventually leads to kidney failure.
All three forms of the disease are treatable and curable and all three forms can be potentially fatal. Often dogs that survive renal Leptospirosis will have chronic kidney disease for the rest of their lives.
Treatment is accomplished with the use of antibiotics and, if the disease is caught early enough, is generally successful. Cases of Leptospirosis in North America are fairly rare, thanks to the development of a vaccine. Puppies are inoculated for the disease as early as six weeks of age and receive annual renewal shots to maintain their immunity.
Vaccination and clean, hygienic conditions are the best way to avoid Leptospirosis in dogs. If the animal is not able to come into contact with disease carrying rats and their urine, the dog is unlikely to become infected, even if unvaccinated. The leptospirosis vaccine is the most likely of all dog vaccinations to cause an adverse reaction in the dog. This reaction is generally mild and most often includes lethargy, loss of appetite, and depression. These effects last only a few days and afterward the dog is fine and, more importantly, protected from the disease.
Leptospirosis is one of the nastier diseases a dog can get and no one wants to see his or her pet suffer with this illness. Fortunately, thanks to the existence of a good vaccine, few dogs have to endure this life threatening illness in today’s day and age.
