NO.1 Heart Disease

Symptoms: Easy to breathe and tired

Basically, the symptoms of heart disease in dogs are very similar to those in humans, and are related to obesity and aging. But what’s worse is that owners often delay medical treatment due to negligence, leading to the death of dogs; there are also dog breeds that are easily excited, often due to ignorance. The tragedy of acute shock occurs when children or relatives and friends come to visit and are given inappropriate excessive exercise.

In addition to considerable experience, doctors who diagnose heart disease must also have the necessary medical testing equipment for examination. This can be supplemented by long-term medication, regular follow-up, and correct feeding and management to ensure safety at all times.

Preventive treatment methods: avoid dog obesity and exercise appropriately

NO.2 Infectious diseases

Symptoms: Increased body temperature, lack of energy, anorexia, vomiting, diarrhea, and acute watery hemorrhagic diarrhea.

The most common fatal malignant infectious diseases are canine distemper and canine parvovirus enteritis. In addition to the fact that the owner has not properly vaccinated (the vaccination rate is less than one-third), the dog cannot manage its living environment independently. Dogs are indeed much more enthusiastic when meeting and greeting than humans, which often leads to disease transmission. Therefore, the best advice is to get vaccinated regularly and try to avoid the chance of infection. If you have a new dog member in your home, Remember to ask a doctor to do a health check first and isolate for a period of time for observation.

Among these accidents, heat stroke is the most easily ignored cause of death. The heat dissipation function of dogs is to dissipate heat through the evaporation of liquid from the tongue, soWhen the outside world becomes hot and humid, dogs are prone to heat stroke, resulting in insufficient blood flow to the liver and kidneys, causing brain hemorrhage and hematoma, followed by epilepsy, tremors, and coma. The fatality rate is very high, depending on the breed. It is said that Pekingese dogs, bulldogs, and pugs are most susceptible to heat stroke because of their short noses.

Prevention and treatment method: The only way is to ask the owner to be really careful.

No.4 malignant tumor

Symptoms: Rarely symptomatic

In fact, malignant tumors in dogs are often ignored in the clinical diagnosis and treatment of veterinarians. In particular, elderly dogs are often directly considered to simply die of old age. Basically, although dogs are easy to gain weight in their diet, they do not have as many carcinogenic foods as humans, and they are not likely to drink alcohol or stay up late in daily life, so the incidence rate is therefore reduced.

How to reduce the occurrence of malignant tumors? Birth control for female dogs can reduce the occurrence of mammary tumors. Birth control for male dogs can reduce the occurrence of prostate cancer. If you find that your dog has cryptorchidism, it should be surgically removed as soon as possible to avoid stromal cells.

The method of treating heartworms is deworming. This process is relatively complicated, and the doctor must be quite professional. Before deworming, the dog’s heart and lung function needs to be evaluated, including a Duppler color cardiac ultrasound examination, and then Give the most appropriate treatment.

The incidence rate in male dogs is three times that of female dogs. times; the third type of damage to lung function, that is, damage to the tissue between the alveoli and the alveoli, is often a secondary symptom of canine distemper infection; the fourth is bacterial pneumonia, which is more likely to occur in large male dog puppies who exercise a lot Higher; finally, there is immune pneumonia, in which congenital immune deficiency causes lung infection, and heartworm infection is also a common cause.
