Leptospirosis. What it is and where does it come from?
We give all our foster babes the LEPTO vaccination, but many folks never heard of it, so here we go!
Lepto is a disease that is frequently contracted by dogs drinking from standing water, such as puddles or ponds. A dog with Lepto will become extremely sick and can sometimes be fatal. This disease is a bacterial infection that enters your pup's bloodstream.
Here are some signs and symptoms:
✅ Fever.
✅ Vomiting.
✅ Abdominal pain.
✅ Diarrhea.
✅ Refusal to eat.
✅ Severe weakness and depression.
✅ Stiffness.
✅ Severe muscle pain.
So HOW does a dog get this virus?
Dogs may develop leptospirosis when they come into contact with the urine of infected animals. This encounter is most likely to happen in the stagnant water found in puddles, ponds, bogs, and waterlogged soil. If urine is present in the water, Leptospira may enter a dog’s body when the pet drinks or moves through the water.
This is why we encourage pet owners to dump out pots, containers, even kiddie pools, and refresh when they have standing water.
The water in muddy areas, puddles, drainage ditches, ponds, and shallow lakes is potentially dangerous. Wild or domestic animals may deposit urine containing bacteria into the water, or the urine may drain into the water from the surrounding area. In urban areas, garbage soaked with rat urine can transmit the bacteria. Even a damp patch of garden or soil can contain the bacteria if an infected animal urinates there. It's possible for one dog to transmit the infection to another one.
Can it be treated?
Treatment often includes the administration of antibiotics and, if necessary, intravenous or subcutaneous fluids. Antibiotic treatment is often effective, and dogs frequently recover from the illness. Serious damage to the kidneys or liver makes successful treatment more challenging, however. Unfortunately, fatalities do occur, despite medical attention. The disease always needs to be taken seriously.
The best course of action is prevention.
✅ Don't allow dogs to drink stagnant water such as the water in puddles and ponds. Stop them from entering these areas as well.
✅ Stop dogs from entering drainage ditches.
✅ If you see notices by lakes advising people of bacterial contamination, don't let dogs enter the lake. If one type of bacterium can survive and multiply there, it's possible that others can, too.
✅ Clear gardens of items that may attract wild animals, such as fallen fruit and garbage.
✅ Remove or enclose piles of wood and thin out dense shrubbery that may attract rats and mice.
✅ Improve the drainage in areas of a garden that are continually damp.
✅ Don't leave water sitting in children's wading or paddling pools for long periods of time.
✅ Try to keep your dog's immune system strong by giving him or her good food and adequate exercise.
✅ Investigate the use of a vaccine as a preventative measure.
NOTE: The bacteria that cause leptospirosis can be spread from dogs to people. The bacteria that cause Leptospirosis are spread through the urine of infected animals, which can get into water or soil and can survive for weeks to months. Humans and animals can become infected through contact with this contaminated urine (or other body fluids, except saliva), water, or soil.
