Vaccinations play a critical role in your dog's health. Knowing the importance of vaccines in dogs may help you decide on the next course of action to take towards keeping your dog healthy and happy. Puppies receive their first set of vaccinations at their birth. The first set is commonly referred to as de-worming and requires the mother to ingest a deworming pill. This pill is typically given at the end of three weeks from birth by the vet. After this, the puppy begins a round of other vaccines within 14 days of birth. The standard course of treatment is to injections over a 14 day period that include a primary injection at 10 days and a secondary injection at 14 days. The secondary injection is given at 20 days after the primary vaccination. Some vets recommend a booster at 24 hours after the primary vaccination is given. The primary and secondary injections are typically administer every four weeks. Leptospirosis is a bacterial disease that can be contracted by dogs that have been infected with Leptospira probes. Blood samples from infected dogs are needed to diagnose the disease. Treatment generally requires antibiotics and is supportive care. If the bacteria are resistant to the treatment procedure and if the dog's primary antibiotic is non-ad gerate, a cortisolodication may be employed to avoid dogs from becoming dehydrated. Infective canine hepatitis is a disease of the liver caused by canine adenovirus. The symptoms are vomiting and diarrhea. This disease is often not diagnosed in its early stages and can be a killer. Distemper is a virus that may be contracted by canines and transmitted by direct contact with infected stool. The most common form of canine distemper is through infection with a respiratory irritant. Other forms include bacterial, viral, and parainfluenza. Training infected dogs to be non-preyrophages is important to avoid the spread of this disease. Food exposure is another common way dogs can be exposed to infections. A few table scraps may be unwittingly infected when you change your dog's diet without the veterinarian's knowledge. Ensure that dog food is properly cooked and handled. Canine coronavirus is an infection of the nose, specifically the sinuses. This disease is highly contagious and is transferred through the breathing medium, nasal or gastrointestinal. Other forms include respiratory and neurological. Consistent symptoms include heavy or short breathing, fever, and lethargy. Death can occur secondary to canine coronavirus and is common up to 70% of the time. Lyme disease is caused by bacteria from the deer tick and is common in the United States where reinfection is common. This disease is usually not diagnosed until 1 to 3 weeks after infection. Symptoms in dogs include lethargy, fever, limping, depression and joint pain. Leptospirosis is caused by bacteria and spread through the urine of infected dogs. This disease has several forms, the most common being leptospirosisents and leptospirosis syndromes. Symptoms in dogs include fever, depression, lack of appetite, yellow eyes and runny or pimple nose. Leptospirosis can be treated with antibiotics. Vaccinosis is another form of the disease where the animal's white blood cell changes to an antibiotic known as penicillin. Getting annual vaccinations for rabies and other vaccinations should help protect your dogs from these three common infections.
