What's the reason why dogs are swollen and fat? What should we do?

When summer comes, the weather becomes humid and sultry, which is a hotbed for bacteria, lice and parasites. Spring and summer are the seasons when dogs are most prone to skin diseases. Owners should pay more attention to the dog's physical condition, hair length and cleanliness. There are many reasons for skin allergies or skin diseases. Absorb certain substances due to eating, unbalanced diet, inhalation of pollen, dust and other particles, and contact with chemicals (cleaning liquid, etc.). ), dogs, puppies or elderly dogs that are stimulated by insect bites and shearing, suffering from kidney disease or liver disease have weak resistance and decreased immunity. It can also cause skin allergies or skin diseases. Skin allergy or dermatosis can make dogs feel itchy, so they will lick, scratch and wander in the affected area, which will make the affected area appear wounds and make it easier for bacteria to invade, thus aggravating the condition and affecting the life of dogs. The following are some common skin diseases: 1) Fungal skin diseases: Fungal skin diseases refer to some skin diseases caused by fungi parasitic on the fur, epidermis and toes of dogs. Dogs are infected with fungal skin diseases, which will initially start from the face, ears, limbs and toes and gradually spread to other parts of the body. Symptoms: Fungal dermatosis with alopecia and hair follicle death. With the deepening of the disease, the wound will ooze, the affected area will be itchy, scales or scabs will appear on the epidermis, pus will appear under the scab due to infection or small pustules will appear on the skin. 2) Eczema Eczema is an inflammatory reaction of dog dander. If the dog's wound is inflamed, it will feel abnormal itching, and then scratch the affected part of the skin with its claws, which will aggravate the damage and infection of dandruff and form a vicious circle. Symptoms: the affected area of eczema will turn red in the early stage. Then in severe cases, there will be sticky secretions, and then there will be pustule water oozing from the dander. If you don't pay attention, the dog's dander will turn yellow and harden, and skin necrosis will occur, which will affect the dog's life. 3) Scabies (skin scabies) Scabies is a kind of canine skin disease that can be transmitted through contact and cross infection, and the probability of transmission is quite high. There are two kinds of scabies, 1 and scabies, which are caused by a species called Bigfoot. Remember that this scabies can be transmitted from dogs to people. Although it will not parasitize and reproduce in the human body, it will also make people feel itchy and uncomfortable, so dog owners must pay more attention! Symptoms: Therefore, the disease will be severely itchy, and the dog will keep scratching the affected area, hoping to stop the itching feeling. At first, it only appeared around the dog's ears, eyes, mouth and nose. But this scabies will spread all the way to the neck and back, and in severe cases, it will cover the whole body and make the hair fall off. (SARCOPIC) The main reason is that [bigfoot] pierces the epidermis to lay eggs and then hatches the adults. This can cause itching, redness and inflammation of the dog's skin. 2. Most of scabies are parasitic in hair follicles. Generally, dogs have a small amount of parasitism, which rarely causes too much trouble. However, when dogs are affected by environment, diseases and drugs, their body resistance is weak and their immunity decreases (especially puppies and old dogs), they will gradually spread into skin diseases. Symptoms: at first, a small part of the hair around the eyes will fall off, and then it will slowly spread to other parts of the body. However, the symptoms of scabies are very obvious, so dog owners can often find the disease in the early stage and receive treatment. Note: When the above two kinds of scabies are serious, there will be lumps and sometimes scales. More seriously, liquid and odor will seep out, mostly bouts of rancid odor, so the impact of this disease on dogs and dog owners can never be ignored. Prevention: There are many reasons why dogs get skin diseases, not only bacterial infections or mosquito bites, but also some nutritional deficiencies and decreased resistance/immunity. If you want to avoid and prevent skin diseases in dogs, you need to pay attention to the following points: 1) Eat a healthy and balanced diet-it is suggested that you can choose some natural dog food or experts specially prepare dog food for the dog's skin and hair to give the dog comprehensive nutrition and improve its immunity and resistance. 2) Remember to see a doctor when you encounter skin diseases-although there are many causes of skin diseases, the symptoms are generally similar. If the dog unfortunately gets a skin disease, it's best to consult a doctor. Don't throw medicine and stones about. 3) Keep the home environment clean-disinfect and clean the dog's haunts regularly, and remember to clean the residual detergent (because some chemicals in the detergent can cause dog skin allergies). 4) Keep the dog's body dry and clean-every time you take a shower or get wet by rain, you must blow dry your body to prevent the dog's body from getting wet and becoming a hotbed of bacteria. 5) Groom the dog regularly-spring is the season for dogs to change their hair, so that the fallen hair won't stay on their bodies. After each comb, the hair is more ventilated and dry, reducing the growth of bacteria. 6) Improve the dog's self-defense system-for example, putting a lice repellent belt on the dog or properly using lice repellent and parasite drugs can help the dog avoid the nuisance of lice and parasites, thus reducing the chance of getting skin diseases.
