Parasitic diseases

We will start the article on the most common diseases in dogs talking about parasites, which can be internal or external, depending on where they are housed:

External parasites

  • Fleas: Fleas are very small parasites that frequently affect canids. They are easily transmitted and reproduced with amazing ease. We can easily observe them by observing the mantle. Discover in AnimalWised how to eliminate fleas from your dog.
  • Stable fly: these parasites are common in rural settings and feed on the blood of animals, which also tends to cause severe anemia if not treated properly.
  • Ticks: there are many different species of ticks and some are truly dangerous, which can cause a paralyzing effect on the dog. They should never be stretched since we could leave remains of the animal in the dog's dermis. Find out all about ticks on dogs.
  • Leishmaniasis: these parasites are transmitted through a vector, the sandfly, and multiply in the white blood cells of the dog. The most common symptoms of leshmania are weight loss, fever, anemia, arthritis ... There is no effective treatment to cure leishmaniasis, however, with veterinary follow-up, a good quality of life can be offered to the dog that suffers from it..
  • Scabies mites: is a skin disease caused by mites. There are two different types of scabies, sarcoptic and demodectic. It is a parasitic disease that is transmitted very easily but that can be treated. In some very serious cases it can leave marks for the rest of the dog's life.
  • Toxoplasmosis: it is an intracellular parasite. In general we can speak of a slight risk, since the treatment is very simple, however, we must be concerned when it affects pregnant dogs. It can be identified by neuromuscular, respiratory, and gastrointestinal symptoms. In most cases it appears in dogs under 1 year old.

Internal parasites

  • You had: they are flatworms that lodge in the intestine of the dog, feeding on the food that the animal ingests. Animals are often infected by coming into contact with contaminated feces, raw or undercooked meats. In the early stages it is difficult to detect.
  • Worms: there are different types of worms that can affect our dog. An infestation of parasites can be noticed through the feces, which show small worms, similar to grains of rice.

The veterinarian will help us prevent a parasite infestation by monitoring a deworming calendar. There are many products available on the market, such as pills, necklaces, pipettes ... However, the most important thing is that they are always veterinary prescription products. In addition, it will be essential to strictly follow the guidelines offered by the professional.

Viral diseases

There are diseases that are caused by a virus for example:

  • Coronavirus: it is a viral and infectious disease that affects all types of dogs, but especially puppies not yet vaccinated. It can be detected the moment we see that the dog has abundant diarrhea, vomiting and we even observe weight loss. There is no vaccine for canine coronavirus, it will be the veterinarian who counteracts the symptoms caused by the disease.
  • Hepatitis: It mainly affects the liver and can have different causes, including viral. The main treatment is based on alleviating the symptoms and if it is not cured it can become chronic, causing liver failure. Find out more about hepatitis in dogs.
  • DistemperDistemper is a highly contagious disease that mainly affects young, unvaccinated or elderly dogs. There is no treatment, so the vet will perform a series of care for the infected dog to counteract the effects of distemper, basically identified by a runny nose as well as other symptoms such as fever or dehydration. Vaccination is the best way to prevent this disease.
  • Parvovirus: It is rare that it affects vaccinated adult dogs, this deadly virus appears especially in puppies and lasts for 10 days in which, if the dog does not receive the correct treatment, it has a fatal outcome. Like almost all viral diseases, it does not have a specific antidote, but is based on trying to alleviate the patient's symptoms. Symptoms are depression, fever, and dehydration. Find out all about canine parvovirus at AnimalWised.
  • RageKnown and feared, rabies is a tremendously deadly disease. It is transmitted through bites, direct contact with mucous membranes or saliva. It is identified by extreme violence without any provocation. There is an anti-rabies that must be administered when they are puppies, because once infected, the dog is considered condemned to death, there is no vaccine that can treat it. Currently fewer and fewer countries have cases of rabies.

Hereditary diseases

Hereditary or congenital diseases are those that develop due to the dog's own genetic inheritance. The most commons are:

  • Hip dysplasia: It develops over time, from 4 or 5 months of age, although it usually appears in older dogs. It affects large or giant dogs causing lameness or difficulty in movements and, although it is a hereditary and degenerative problem, factors that can aggravate it intervene, such as rapid growth, overfeeding or intense physical exercise. Find out more about hip dysplasia.
  • Artosis: Osteoarthritis is another hereditary disease that causes wear and tear on the dog's joint. This causes difficulty in their movements and pain that must be treated with anti-inflammatories prescribed by the veterinarian..
  • Rheumatism: it affects the joints and their cartilage, it is a degenerative disease. Symptoms are stiffness, swelling, and pain. The vet may prescribe glucosamine condoitin and other treatments that will relieve and improve his condition..
  • Glaucoma: it is an excessive accumulation of fluid in the dog's eye. It can occur spontaneously since it is a hereditary disease but it also develops in dogs that have suffered excess pressure on the neck (generally associated with the animal's collar). Discover everything about glaucoma in dogs.

Neurological diseases

Neurological diseases are those that affect the central and peripheral nervous system, which includes the brain, cranial nerves, nerve roots, muscles ... Although they are rare, it is vitally important to detect them:

  • Epilepsy: Epilepsy in dogs is an electrochemical discharge from the brain that can appear at any time. The seizures are repeated practically throughout the life of the dog that suffers it. Episodes can be controlled by medication prescribed by the veterinarian.
  • Vestibular syndrome: In vestibular syndrome (which is actually a symptom) the inner ear, the vestibule cochlear nerve, the vestibular nucleus, and the anterior and posterior middle tract can be affected. We will observe that the dog has balance problems, a crooked head or that it walks in circles.
  • Meningitis: Meningitis is an inflammation of the meninges, the membranes that line the brain. It is an unusual problem but it must be treated urgently as it can have fatal consequences for the dog. The most common symptoms are the dog's loss of coordination and high fever.

Bacterial diseases

Caused by bacteria, these types of diseases can be treated with the use of antibiotics:

  • Canine leptospirosis: It is transmitted through urine and both dogs and rats can be carriers, chronically storing the bacteria without developing the disease. If it is not treated in time it can cause death. Some of the symptoms are fever, diarrhea, and vomiting with blood and dark urine. Find out more about canine leptospirosis.
  • Periodontitis: it affects the periodontium (gum, tissue, bone and ligament) and is derived from the accumulation of tartar and plaque, which makes the proliferation of bacteria possible. These gradually invade the sac, the cavity where the root of the tooth is and end up causing serious infections or tooth loss. The best way to avoid this disease is prevention.
  • Pyometra: it is a bacterial infection characterized by the appearance of pus inside the cavity of the uterus or womb. The symptoms of pyometra are discharge of pus through the vagina. Formerly the treatment was only surgical and the ovaries or the womb of the bitch were removed. Today we have drugs that make it possible to study it before removal..
  • Cystitis: it is a disease produced by bacteria that affect the urinary system of the dog by inflaming its bladder. Cystitis must be treated promptly to prevent it from becoming chronic.

Other common diseases in dogs

In addition to those mentioned above, there are other diseases such as:

  • Cancer: it can affect all types of dogs although it is common to occur in older dogs. The most common is to detect the presence of tumors on the dog's skin, but they can also develop internally. It is very important to go to the vet for the analysis of the lump.
  • Gastric torsionGastric torsion usually occurs when the dog overeats and drinks, exercises after eating, or has a history of gastric volvulus. It is very important to be treated urgently to save the life of the animal.
  • Skin allergies: Like people, dogs can also suffer from skin diseases such as allergies. We must be careful and go to the vet if we observe that our dog suffers from it.
  • Diabetes: sugar is on the list of prohibited foods for dogs, not only because it encourages blindness but also because it also causes diabetes. Consult your veterinarian about the treatment your dog needs if you observe extreme thirst, weight loss, cataracts, increased appetite and that he urinates frequently..
  • Cryptorchidism: consists of the incomplete descent of one or two testicles. It must be diagnosed as soon as possible and requires surgical intervention. In some cases it is hereditary.
  • Otitis: it is about inflammation of the inner, middle or outer ear. It can appear from allergies, bacteria, parasites or foreign bodies. Your veterinarian will investigate the itching, redness or infection that your dog may have, cleaning it carefully and offering you a treatment according to the reason why it occurred.
  • Diarrhea: it is a very common problem, especially when we change our dog's food or offer him human food. Discover home remedies for diarrhea in dogs.
  • Cold: Like people, dogs are susceptible to colds when they are subjected to low temperatures. Cold in dogs is very easy to treat but if symptoms persist it is important to go to the vet.
