Dogs, like humans, can experience a wide range of health conditions. Knowing the symptoms, treatments, and when to seek veterinary help can make a big difference in your pet’s health. Below are some of the most common illnesses seen in dogs and puppies.  

Parvovirus (Parvo)

Symptoms – What to Look Out For:

– Severe vomiting

– Bloody diarrhea

– Loss of appetite

– Lethargy

– Dehydration

Medication:

There is no direct cure, but supportive care including IV fluids, anti-nausea medication, and antibiotics are administered by a veterinarian.

Self Medication:

Do not attempt to treat Parvovirus at home; it is life-threatening.

When to Contact or See a Vet:

Seek immediate veterinary care. Delay can be fatal.<br>

Giardia

Symptoms – What to Look Out For:

– Diarrhea (watery, intermittent, or containing mucus and blood)

– Vomiting

– Weight loss

– A poor coat

– Decreased appetite

– Lethargy

– Flatulence (gas)

– Fatty (steatorrhea) and green-tinged stool

Transmission:

– Ingesting the parasite through contaminated water, soil, or feces

– Interacting with other infected dogs in places like daycare or breeding facilities

Diagnosis:

Veterinarians diagnose Giardia through a stool sample analysis. An ELISA test can provide quick results and check for the presence of the parasite.

Treatment:

Treatment typically involves a course of antibiotics prescribed by your veterinarian. Medications like metronidazole (Flagyl) or fenbendazole (Panacur) are commonly used. For resistant cases, both medications may be used together. Rehydration fluids and nutritional support may be needed for severely affected dogs.

Prevention:

– Hygiene: Practice good hand hygiene, especially after handling feces.

– Cleanliness: Regularly clean your dog’s bedding, toys, and feeding areas.

– Environment: Dispose of feces promptly and disinfect contaminated areas.

– Water: Ensure your dog only drinks clean, uncontaminated water.

– Bathing: Bathe your dog at the end of treatment to remove any cysts from their fur.

Coccidia

Symptoms – What to Look Out For:

– Most infections are subclinical: Many dogs, especially adults, show no signs of illness, though oocysts are found in stool.

– Clinical signs in puppies and immunocompromised dogs: severe watery diarrhea, abdominal distress, vomiting, and dehydration.

– Severe cases: In very young or sick dogs, severe infections may be life-threatening.

Diagnosis:

Veterinarians usually perform a fecal flotation test to look for microscopic coccidia oocysts in a stool sample.

Treatment:

A veterinarian will prescribe an antiprotozoal antibiotic to shorten the illness, reduce clinical signs, and decrease oocyst shedding. Supportive care, including intravenous fluids, may be required in severe cases. Rigorous sanitation is crucial to eliminate oocysts from the environment and prevent reinfection.

Prevention:

– Good hygiene: Frequent removal of feces and thorough cleaning of contaminated areas, including crates and bedding.

– Disinfection: Clean surfaces with appropriate disinfectants and use steam cleaning or high heat for bedding and toys.

Kennel Cough
