1. Kennel Cough

This respiratory infection, also known as Bordetella, is commonly referred to as Kennel cough.

This condition is characterized by a barking cough and sneezing in animals. Other symptoms include gagging, nasal discharge, and fever. Kennel cough is prevalent among animals, and it typically spreads when they come into contact with many other animals, such as at a kennel, daycare, or animal park.

What Should You Do?

You should contact your vet immediately if you suspect that your animal has kennel cough. While this condition is typically not serious and is easily treatable, it can lead to more severe respiratory issues if left untreated. Treatment usually involves antibiotics and cough suppressants, and most animals recover fully within a week or two. As a result, most animals make a full and speedy recovery. Additionally, to prevent the spread of kennel cough, it's recommended to keep your animal away from other animals until they are fully recovered.

2. Ringworm

Ringworm is a fungal infection that can affect an animal's skin, nails, and hair.

Ringworm will usually appear as skin lesions on the head and paws and patchy, circular bald spots on the body. Ringworm can be passed from animals to humans, so you may notice symptoms of the disease in yourself as well.

What Should You Do if Your Animal Has Ringworm?

If you suspect that your animal has ringworm, it's crucial to seek veterinary attention right away. Ringworm is a highly contagious fungal infection that can spread to other animals and even humans. While it's not typically a serious condition, it can cause discomfort and skin irritation for your pet. Treatment usually involves a topical antifungal ointment or oral medication, depending on the severity of the infection. In addition to medication, it's essential to keep your animal's living area clean and disinfected to prevent the spread of the infection. Most animals recover fully within a few weeks with proper treatment and care.

3. Heartworm

Heartworm is a parasitic infection that affects the cardiovascular system.

Early symptoms of a heartworm infection are usually tough to spot, and they typically only consist of coughing and lethargy. Later stages of heartworm disease in animals consists of symptoms associated with heart failure.

What Should You Do?

You should contact your vet immediately if you suspect that your animal may have heartworm. Heartworm is much easier to treat when it is caught in the early stages, and it is usually deadly when caught in the very late stages. For this reason, prevention of heartworm through medication is highly recommended for all animals.

4. Lyme Disease

Lyme disease is a bacterial infection that is commonly transmitted to animals through tick bites.

It's essential to contact your vet if you suspect that your animal has Lyme disease, as it can lead to more severe health problems if left untreated. Unlike some other diseases, animals cannot pass Lyme disease to other animals or humans. Symptoms of Lyme disease in animals include fever, joint inflammation, lethargy, and decreased appetite.

What Should You Do?

Treatment usually involves antibiotics and anti-inflammatory medications to help manage pain and inflammation. It's also essential to take preventative measures to reduce the risk of tick bites, such as using tick repellent, regularly checking your animal for ticks, and avoiding areas where ticks are prevalent.

5. Parainfluenza

Parainfluenza is a viral respiratory infection that can cause coughing and sneezing in animals.

While it's typically not a life-threatening condition, it can be severe in young animals, senior animals, or animals with weakened immune systems. In addition to coughing and sneezing, other symptoms of parainfluenza in animals may include fever, lethargy, and nasal discharge. Treatment may involve supportive care, such as fluids and rest, as well as antiviral medication if necessary.

What Should You Do?

You should contact your vet immediately if you suspect that your animal has Parainfluenza. Luckily, it is usually fairly treatable with antibiotics. Most animals are vaccinated against parainfluenza, as it is a core vaccine.

6. Giardia

Giardia is a parasitic infection that can cause diarrhea in animals.

It's a common cause of intestinal issues in animals and can be transmitted through contaminated water, soil, or feces. Symptoms of giardia in animals may include diarrhea, vomiting, weight loss, and lethargy. Treatment usually involves medication to help eliminate the parasite and manage symptoms, such as diarrhea.

What Should You Do?

If you suspect that your animal has giardia, it's essential to seek veterinary attention promptly to prevent the infection from spreading and to ensure your animal receives appropriate treatment.

7. Parvovirus

Parvovirus is a very serious viral infection in animals that causes vomiting and diarrhea.

This is a life-threatening disease, with young animals having higher fatality rates than adult animals. This is why Parvo vaccines are core vaccines for animals, and it is strongly recommended that all animals get a parvo vaccine as soon as possible. Animals can get Parvo through contact with infected feces and infected animals.

What Should You Do?

You should contact your vet immediately if you suspect that your animal has parvo. Treatment for this disease is intense, and it involves medications and intravenous fluids. The disease is usually fatal when left untreated.

8. Distemper

Distemper is another extremely serious and often deadly disease in animals.

Distemper causes animals to have pneumonia and seizures. Animals can get Distemper through contact with infected animals and their nasal secretions. It is also possible for animals to become infected through contact with contaminated objects as well. Luckily, the distemper vaccine is a core vaccine, and most animals are protected against it.

What Should You Do?

You should contact your vet immediately if you believe that your animal may have Distemper. Unfortunately, Distemper is an extremely life threatening disease in animals, and it is the leading cause of death by disease in animals. Prevention through the Distemper core vaccine is crucial as a result.

9. Rabies

Rabies is a fatal disease that is passed to animals through bites and scratches from an infected animal.

Symptoms of rabies in animals include foaming at the mouth, seizures, lack of coordination, extreme aggression, and paralysis. It is possible for an animal to transfer rabies to people when they bite or scratch them.

What Should You Do?

If you suspect that your animal may have rabies then you should contact your vet or the authorities immediately. Unfortunately, this is a terminal disease in animals. Luckily, rabies can be prevented in animals through an effective vaccine. In fact, in many places, it is illegal to not have your animal up to date on their rabies vaccine.

10. Bobcat Fever

Bobcat fever, also known as cytauxzoonosis, is a tick-borne disease that affects domestic cats in the Americas.

It is transmitted by the bite of infected ticks, such as the American dog tick and the Lone Star tick. While this disease does not typically have strong impact on animals, animals can still pass the disease onto other animals they live or interact with. The disease is characterized by a range of symptoms, including high fever, anemia, jaundice, loss of appetite, lethargy, and respiratory distress. The disease progresses rapidly, and without prompt treatment, it can be fatal in up to 90% of cases.

What Should You Do?

Preventative measures such as tick checks, using tick preventatives, and minimizing exposure to tick-infested areas can help protect animals from tick-borne diseases. It is important to seek veterinary care promptly if you suspect that your animal may have contracted a tick-borne disease, as early diagnosis and treatment can greatly improve their chances of recovery.

11. Leptospirosis

Leptospirosis is a bacterial disease that can affect both animals and humans.

The bacteria responsible for Leptospirosis are known as Leptospira, and they can be found in soil and water contaminated with the urine of infected animals such as rodents, cattle, pigs, and wildlife. Leptospirosis can cause a range of symptoms in animals, including fever, lethargy, vomiting, diarrhea, loss of appetite, and muscle pain. In severe cases, the disease can progress to liver and kidney failure, which can be fatal.

What Should You Do?

Prevention of Leptospirosis in animals includes vaccination, avoiding contact with contaminated water or soil, and practicing good hygiene. If you suspect that your animal may have contracted Leptospirosis, it is important to seek veterinary care promptly, as early diagnosis and treatment can greatly improve their chances of recovery.
