Parvovirus is one of the most serious diseases that can reach puppies such as old dogs. The pathogen causes mostly puppies and sometimes also in older dogs a gastroenteritis whose consequences can be fatal, as a result of State of shock that it can develop. The morbidity rate is 16-35% in unprotected dogs.
It is probably the one that causes the most headaches to breeders regarding vaccination of puppies.
So you go every year to your veterinarian to have your dog vaccinated against this disease which is sadly part of the affections that can have serious consequences. Even dogs vaccinated against this disease may become ill. You will see a little further on the possible reasons for such failures.
There are two types of parvovirus that have been classified by Type 1 and Type 2
Parvoviruses are among the smallest viruses and can also reach humans. What we should be concerned about is the ability of this virus to mutate, which could lead to modified vectors that could no longer be covered by vaccines currently available.
The canine parvovirus pathogen (CPV-2), which appeared in 1978 for the first time, is now spread throughout the world.
CPV-2 is believed to have mutated from panleukopenia which is a condition of feline parvovirus, which is only distinguished by some basic DNA modifications.
The mortality of a canine population exposed and abandoned to CPV-2 virus is around 10%. In southern Spain (Andalusia) where CPV-2 is relatively widespread, the mortality rate of puppies can rise to 80%.
The virus can survive several weeks in the external environment.
You therefore have to do to two types of parvovirus as well as to two antigens formed by the mutation of the virus.
The type 1 parvovirus known as the minute virus (MVC Minute Virus of Canine) little cause abortions (embryonic or neonatal mortality). In the case of young puppies it can cause death in the first 2 months of life.
Canine parvovirus often referred to as parvo is an infectious viral disease caused by parvovirus type 2 (CPV or Canine ParvoVirus 2). There are two variants, which are derived from the mutation, the antigens CPV2 and CPV2b.
Contamination is by direct contact with saliva, infected stools or by excretion following vaccination of 3 to 7 days in the urine.
symptoms:
From 5 to 12 days after contact, the signs are variable; Hemorrhagic gastroenteritis nauseating (24 to 48 hours later), lethargy, fever, vomiting, dehydration and weight loss are rapid.
Can a puppy or an affected dog survive? With relatively low chances it happens that they can survive. It then has antibodies for life, allowing them to fight this disease.
And now let us come to the problem of the vaccination of canine parvovirosis, creating headaches to many breeders. To better understand this problem here is an example of a case which is alas by no means exceptional.
You have acquired from a breeder your puppy you have dreamed of for a very long time. When the time comes, you will get it from the breeder who will give you various documents, including a vaccination notebook showing that your puppy is vaccinated against canine parvovirus. Then suddenly your dog gets sick. You will consult your veterinarian who diagnoses: Your dog is sick of canine parvovirus. You are legitimately dismayed and do not hesitate to show the vaccination notebook which naturally mentions that the dog is perfectly vaccinated against this disease. So why is this dog yet vaccinated suffering from this disease:
Here we return to what should be understood by the vaccination with discernment.
Currently the puppies undergo more or less valid protocols, a whole series of vaccinations at their young age at certain intervals. 4 see more vaccinations against parvovirus and icing on the cake, some veterinarians unfortunately do not hesitate to complete this series of vaccines by administering a vaccination against rabies to knock out the puppies in the best way.
The various canine federations rightly prescribe that puppies should not be given to future owners before they have attained the age of 8 weeks. Some breeders interpret this recommendation for purely economic reasons by: All puppies must be handed over to the new owners at the age of 8 weeks.
The series of vaccinations thus often begins too soon and the efficacy is then all simply not seen largely insufficient. Veterinarians should be aware that as long as the puppies are still breastfed by their mothers and have not yet developed their own immune system against parvovirus, vaccination poses the problem of the effectiveness that veterinarians are trying to More or less valid protocols to circumvent by vaccinations at repetitive intervals, hoping naturally that the protection against this disease will take. This is not exactly what should be understood by: Vaccine with discernment.
By vaccinons with discernment there is an approach that is likely to have much better results:
Vaccinate based on the result of a titration. So by having a quantified indication on hand to assess the best time of vaccination
Proceeding by titration is basically easy to set up. Simply make a blood take of a single puppy from a litter, then draw a title (analysis).
Depending on the titration value, it is possible to determine the best time to vaccinate against canine parvovirus. This best moment is at the lowest values. The chances that vaccination will then take and protect the dog would then be significantly greater. Veterinarians who are used to practicing in such a way have often developed an excellent analysis allowing the choice of the most appropriate time.
A second titration before the delivery of the puppy to the future owners to make sure that the protection against canine parvovirus works is naturally also possible while offering to the future owners a certain guarantee.
