Be awar of insects when your dog is swimming


The bacterium Leptospira causes leptospirosis, which is a severe waterborne illness that has to be treated as soon as possible. There are several Leptospira species found over the globe, but those located in warm, rainy regions seem to be the most common. Humans and dogs may both be infected with the bacterium, although it is more prevalent in dogs. Dogs that often swim in stagnant water bodies, such as rivers, lakes, and streams, are most in danger. A wound or mucous membrane that comes into touch with polluted urine or water frequently becomes infected.




You can be sure it's bad when it has a moniker like "swamp cancer.". Pythium insidiosum, a fungal-like organism, causes an uncommon but serious waterborne illness known as pythiosis. A plant-specific illness called pythiosis may also infect animals, sometimes with disastrous outcomes.


Pythiosis is most typically seen in tropical regions with a lot of standing water, such as the Gulf States (Texas, Louisiana, Florida, Mississippi, Alabama), Southeast Asia, & South America. The organism develops into big, typically ulcerated sores when it adheres to tiny incisions in the body or gastrointestinal tract. Owners may notice huge red itching lumps on their skin if the disease begins there. Owners may experience symptoms such as vomiting, diarrhea, and lack of appetite if the infection spreads to the GI tract. Labradors, a breed well-known for their affinity for water, are the most prevalent victims of the illness.


Blue/Green Algae

If you have a water-loving dog, freshwater lakes & ponds are ideal. However, avoid any bodies of water that have a high concentration of blue-green algae. A blue-green algae hazardous algal bloom occurs when certain environmental conditions are met, which is most typically in the summer (HAB). These microorganisms have the potential to create poisons that are dangerous to both humans and pets.

Blue Green Algae


Toxins from algae may harm the skin, gastrointestinal tract, liver, & central nervous system, among other organs. Pets who have been exposed to various types of toxins may exhibit a wide variety of symptoms, from mild skin irritation to severe respiratory failure, convulsions, and even death. Whether a lake has an algal bloom, dogs should not be allowed to swim there since it is hard to know just seeing if the algae have released poisons. If you get unwell as a result of swimming in water that has an algal bloom, call your veterinarian right once. Severe disease may be fatal.



Many dog owners may aware of Giardia lamblia, one of the numerous tiny parasites that may cause diarrhea in dogs and people. Diseased animals excrete the parasite's eggs, which are robust and may survive for a long period in damp, chilly conditions where they can be transferred to water sources & re-infected with the host.


Giardia, a parasite that has long been linked to human travelers’ diarrhea, may also suddenly cause diarrhea in dogs. It is possible for humans and dogs to get the illness, but since most cases of humans are caused by other humans and are not generally transmitted from dogs to people, this is not considered a big zoonotic disease.



The parasite Cryptosporidium is responsible for one of the most dreadful waterborne infections, cryptosporidiosis. Those who have been infected with the parasite or the illness often refer to them as "crypto.".


There are several Cryptosporidium species found in various animal species, and some of them may infect people when they come into contact. The parasite has a thick exterior shell that protects it from the environment and allows it to survive for a long period, even when exposed to chlorine disinfectants. Recreational water is known to be a source of cholera in the United States. Dogs get sick when they consume contaminated water or food that contains infective oocysts.




The flatworm Heterobilharzia Americana, which causes canine schistosomiasis, is another organism that dog owners in Texas should be aware of in their water-loving pets. While swim or wading in polluted waterways, the organism enters the dog's skin and travels to the liver via the lungs. The adults lay eggs that pass through the GI system and end up in the feces, where they infect the freshwater snails that serve as an intermediate host.




The shaking head, clawing at the ear holes, and stinking head are all symptoms that dog owners with ear infections are likely to encounter in their pets before they really develop into an infection. The most typical reason for bringing a dog to the vet clinic is because of this problem. It is true that there are several possible causes of otitis externa such as bacteria in the water or yeast in the ear canal, but one of those reasons is waterborne.

Chronic ear infections in dogs are most often caused by Pseudomonas aeruginosa. Swelling and a foul-smelling discharge are the results, as also a significant degree of discomfort. It's suspected that Pseudomonas is a prevalent cause of "swimmer's ear" since it's often found in swimming pools."


Is it possible for dogs to develop parasites while they swim?

When dogs are swimming or playing in the water, they may ingest the Giardia parasite and get infected. Go to the vet as soon as your dog develops diarrhea after swimming in water.

What behaviors might you expect from a dog that has parasites?

Intestinal parasites most often cause the following signs and symptoms: Scooting. Vomiting. Diarrhea
