The body temperature rises/fluctuates, and it is difficult to identify the symptoms. The dog’s body temperature in the early stages of infectionThe temperature is as high as 39.5~41℃ and lasts for about 2-3 days. [Tip] ⑴ The normal temperature of the dog's body is 38.5-39.3℃ ⑵ Then it subsides, which is very similar to the characteristics of a cold recovery. The sick dog seems to be getting better, causing most dog owners to relax their vigilance. If you can find a cure at this time, it is very easy to cure. The second time the body temperature rises, the duration is uncertain. (A few cases died at this time) As the body temperature did not drop for the second time, the condition worsened and the fever continued.
The spirit was depressed, but some dogs were particularly lively or quiet, making it difficult for the owner to distinguish the disease. . The spirit is particularly bad. Most dogs are obviously not active at this time and just want to lie down. The spirit goes up and down. Due to loss of appetite and lack of nutrition, it will be difficult to walk, become less likely to move, and become highly depressed and lethargic.
Having a slight appetite and loss of appetite for eating, some will also eat and be particularly repelled by feeding.
The conjunctiva of the eyes is red, the eyelids are swollen, and watery secretions are secreted. The secretion of pus and eye mucus is increasing. The secreted pus will cover the eyes, and the eyes will stick together and cannot be opened. Eye injuries in some dogs are clinically characterized by conjunctivitis and keratitis (keratitis is mostly seen about 15 days after onset, and the cornea turns white). In severe cases, corneal ulcers, perforations, and blindness may occur.
The nose is dry and watery secretions flow out. In a few cases, transitional lesions of nasal skin keratosis can be seen. Micro cracks appear on both sides of the nostrils and pus drains from the nose.
Severe dryness and cracking, more pus leaking out and blocking the nostrils, making it difficult to breathe.
A dog suffering from canine distemper has pus from its nose
Footpads
The footpads of dogs suffering from canine distemper are thickened and cracked, and in a few cases, transitional lesions of keratinized skin on the soles of the feet can be seen.
May present with complex symptoms clinically. Many dogs will experience swelling, hyperplasia, hyperkeratosis, and cracking of the foot pillow (this change will be mentioned in many textbooks and materials). So what significance do these symptoms have in the diagnosis and treatment of canine distemper? In fact, although these symptoms are common to us, they do not have any practical clinical significance. Why do you say this? Because first of all, whether the footpads are thickened or not cannot be used as a basis for diagnosing whether a dog has canine distemper; secondly, thickened footpads cannot be used as a basis for judging the stage of canine distemper; thirdly, whether the footpads are thickened can not be used as a basis for judging the stage of canine distemper. Whether the foot pads return to normal cannot be used as a basis for diagnosing the recovery of canine distemper; and simply looking at the thickened foot pads will not affect the development of canine distemper, let alone endanger the dog's life, so canine distemper The thickening of the footpad does not have any practical significance clinically, so we do not need to observe changes in the footpad during treatment.
Respiratory disease begins with dry cough, and respiratory inflammation is more obvious. Symptoms of cough, tracheitis, and pneumonia often occur and last for more than one month. Later, it turned into wet cough and difficulty breathing
Vomiting/diarrhea started with constipation, and soon diarrhea, with foul-smelling feces, sometimes mixed with blood and air bubbles. Gastrointestinal infections include vomiting, diarrhea, and intussusception. If the puppy is also infected with intestinal parasitesworms, intussusception may also occur. (※If no measures are taken to stop it, it will eventually lead to death from severe dehydration and weakness)
Nervous Symptoms About 10 to 30% of sick dogs develop neurological symptoms (convulsions, epilepsy, convulsions, etc.). Some have symptoms of "occasional twitching". For example, when stimulated, the mouth twitches like chewing and spits. The symptoms disappear after the dog calms down. But this is a very obvious sign of "continuous twitching". ●Nervous symptoms appear, mostly between 7 and 21 days, and some may show neurological symptoms from the beginning. ●Because the canine distemper virus invades the central nervous system at different locations, the symptoms vary. ●The virus damages the brain and manifests as epilepsy, circling, abnormal standing posture, unsteady gait, ataxia, foaming at the mouth, paroxysmal twitching of masticatory muscles and limbs, persistent twitching and other neurological symptoms. It is easy to leave sequelae. ●Transplacental infection of "puppies" can produce neurological symptoms in 28 to 42 days.
Skin Some dogs develop pyoderma in the middle and late stages of infection or after recovery. In some dogs, multiple abscesses appear, and the abscess areas initially appear indurated. If some dogs suffer from pyoderma in the later stages, the induration becomes soft, the skin in the center becomes thinner, and deep ulceration occurs, with pus and blood flowing out. In severe cases, large-scale ulceration may occur.
Other symptoms ●Puppies also develop osteoid sclerosis of the metaphysis (chondrodysplasia of the metaphysis of long bones). ●Sneeze. ●In the middle and late stages of canine distemper, there are big red spots, edema, purulent papules, vesicles, etc. on the skin of the lower abdomen and medial thighs. Some may form hoof sclerosis, which is clinically characterized by keratosis of the foot pads and keratosis of the nose. Cases causing multiple symptoms of neurological canine distemper. Symptoms vary depending on where the canine distemper virus attacks the central nervous system. The virus damages the brain and manifests as epilepsy, circling, abnormal standing posture, unsteady gait, paroxysmal twitching of masticatory muscles and limbs and other neurological canine distemper symptoms. The prognosis of this type of neurological canine distemper is usually poor. ●Body pain, screaming in pain. Some internal organs begin to be affected, and the dog will scream in pain when picked up. ●In the early stage, the corners of the mouth will be eroded. ●Nervous symptomatic canine distemper is a typical manifestation of canine distemper in the late stage, and most of them appear about 10 days after the above symptoms. Late stage: Symptoms of neurological canine distemper appear. In addition to the symptoms of canine distemper in the mid-term, affected dogs occasionally also show symptoms of neurological canine distemper, such as wilting, muscle pain and weakness, paroxysmal muscle spasms, balance disorders, circular movements, epileptic panic and coma, etc. , generally the dog will die after this symptom lasts for 1-2 weeks.
