What is Leptospirosis? (or Lepto, for short)
Leptospirosis is a deadly bacterial disease commonly spread by wildlife.
Lepto has been diagnosed in all types of dogs, and all breeds and sizes are at risk.
Common Lepto carriers include raccoons, deer, opossums, squirrels and rats. Livestock can also carry the disease.
Lepto bacteria can survive for long periods in water and on wet grass.
The numbers of canine Leptospirosis cases have risen in recent years. Today, Lepto is the number one infectious cause of acute kidney failure in dogs.
Lepto should be considered if your dog has a fever, vomiting, loss of appetite, diarrhea or lethargy. Early recognition is important for a full recovery.
How is my dog exposed?
Lepto bacteria are shed in urine. Dogs become infected when they come into contact with fresh urine from infected carrier animals.
Infection occurs when dogs wade, walk or play in contaminated soil or water or drink from contaminated water sources.
The bacteria can enter through a cut in the skin or mucous membranes, such as the eyes, nose or mouth.
Take steps to protect-
Remove food, garbage and nesting materials from your yard to minimize wildlife activity.
Discourage your dog from drinking standing water and change outdoor water sources every morning.
Vaccinate your dog against Leptospirosis annually.đžđž
