Do you know what diseases these symptoms of dogs represent?

Keeping a pet dog is a way for modern people to relax, and it is even a spiritual sustenance for the owner. The relationship between pets and people is getting closer and closer. Some owners treat their pets like their own children, often sleeping and eating together; however, too close a relationship often leads to zoonotic diseases. In addition to inducing allergic symptoms, pets may also be infected with other diseases. Therefore, only by having a comprehensive understanding of some diseases that pets may be infected or transmitted can early prevention and early treatment be achieved.

CCV symptoms (canine coronavirus)

Canine coronavirus enteritis is an acute infectious disease caused by an epithelial cell-tropic virus that preferentially invades the intestinal epithelial cells at the ends of the villi, thereby destroying the intestinal villi, causing them to atrophy and fuse, and then causing varying degrees of diarrhea.

Key points Although severe endemic enteritis associated with kennels or dog shows occasionally occurs, most CCV infections are subclinical.

CCV-infected dogs can continue to excrete asymptomatically for several months and spread rapidly through the fecal-oral route.

Most dogs infected with CCV do not show clinical symptoms, but some infected dogs clearly show sudden loss of appetite, lethargy, vomiting and diarrhea. The characteristics of diarrhea range from soft to watery stools, sometimes with mucus and blood .
Most dogs infected with CCV do not have fever and mild symptoms, so it is easy to be confused with many other short-term mild diarrhea caused by non-specific causes.

CDV symptoms (canine distemper virus)

Canine distemper virus (CDV) belongs to the Paramyxoviridae family and the Morbillivirus genus. It is a single-stranded negative-strand RNA virus with weak resistance. It is sensitive to heat, dryness, ultraviolet rays and organic solvents, and is easily killed by sunlight, alcohol, ether, formaldehyde, etc.

The clinical symptoms of CDV infection vary in severity depending on the virus species, environmental factors and individual response to infection. Clinical symptoms are mainly limited to the upper respiratory tract, so coughing and runny nose will be obvious. Unimmunized puppies are likely to have severe symptoms such as pneumonia, diarrhea, dehydration, anorexia, etc. Vomiting is also common in the early stages of infection. Neurological symptoms appear 1-3 weeks after recovery from acute infection. The neurological symptoms caused by the virus are obviously progressive and rapidly deteriorate. Dogs with neurological symptoms, if they can survive, may also have permanent sequelae. (For example: epilepsy, hind drive weakness, etc.); if CDV infection occurs before the eruption of permanent teeth, the enamel may be underdeveloped. Other symptoms include optic neuritis, retinal degeneration and base necrosis. The clinical disease type of this disease is complex and diverse, lacking in characteristic features.

CPV symptoms (canine viral enteritis)

Canine parvovirus type 2 (CPV-2) can cause acute highly contagious enteritis in dogs. The disease has been endemic around the world since the late 1970s. Since the 1980s, CPV-2a, CPV-2b, and CPV-2C variants have been discovered, and CPV-2b has now become the most prevalent strain in North America.

Key points CPV has a tropism for rapidly differentiating cells in the intestine, bone marrow, lymphoid tissue, etc., and can therefore cause intestinal villus necrosis, severe diarrhea, leukopenia, and lymphoid depletion.Parvovirus may cause anorexia, depression, fever, vomiting, intractable watery diarrhea (profuse and hemorrhagic), and rapidly progressive dehydration.

Those cases with bacterial sepsis or endotoxemia may eventually develop hypothermia, jaundice, and hemorrhagic diathesis (disseminated intravascular coagulation).

Severe cases may result in death, especially in puppies and susceptible breeds, and are usually attributed to dehydration, electrolyte imbalance, endotoxic shock, or severe bacterial sepsis associated with leukopenia. Hypoglycemia is common in septic puppies.

The severity of clinical disease can be exacerbated by factors such as stress, overcrowded or unclean kennel conditions, secondary bacterial infection, and concurrent diseases such as distemper, coronavirus, salmonellosis, campylobacteriosis, and intestinal parasites.
Mild or asymptomatic infections are more common in unimmunized adult dogs, and seroconversion occurs despite the absence of clinical signs.

GIA symptoms (Giardia antigen)

Giardia is a common intestinal parasite in dogs and cats. It is highly contagious and can be cross-transmitted between owners and pets. It is the main cause of intractable diarrhea. The main clinical manifestations of the disease are mild or severe diarrhea, which is persistent or intermittent. The initial diagnosis of Giardia is difficult. There are many causes of similar clinical symptoms. It is often necessary to consider microscopic examination or ELISA methods based on the effect of multiple antidiarrheal treatments, which can easily cause delays in the disease.

Giardia is difficult to eliminate and may be resistant to certain drugs. In particular, the oocysts in feces are very resistant to the environment. A small amount of Giardia oocysts can re-infect dogs, cats and humans. In addition, other protozoa of dogs and cats may also be mistaken for Giardia. Giardiasis poses a greater threat to dogs and cats with compromised immune function (such as those in the period of feline AIDS infection, the recovery period of canine distemper infection) and young dogs and cats. International authoritative veterinarians recommend that pets be tested for parasites regularly every six months. For young and immunocompromised dogs and cats, the frequency of testing can be appropriately increased, especially before deworming.

If you find that your dog is not feeling well, you can check the above symptoms to make a preliminary diagnosis of the disease. If you have the conditions, you can do a test at home first, and then take the dog to the hospital according to the situation.
