Vaccinating can be adapted to the titers, age and living conditions of your animal. Most vaccines against parvo, dog disease and infectious hepatitis in the dog work for at least 3 years. Scientific studies show that protection often lasts longer than 3 years.

The VacciCheck test indicates whether your dog has antibodies to the above diseases that are vaccinated against.

The amount of antibodies in the blood (the titer) is the size for the defense of your animal. If the titer is high enough, vaccination is not necessary.

It's a simple blood test, it takes one drop of blood, and within half an hour the rash.


A puppy receives maternal antibodies from the mother and when drinking the first breast milk. For this reason, titting puppies is of great importance, because vaccinating a dog that still has antibodies is not useful: vaccination does not strike. My Fleur was only grafted when she was 23 weeks old and was released for vaccination for three years in spring 2017. Femke was vaccinated in 2016 and now free for 3 years, still more than enough antibodies.


Vaccination Kennel Cough, Leptospirosis, Lyme and Rabies



Kennel cough can be seen as flu in dogs. They cough terribly and the sound goes with you through marrow and leg. When they get it, it is to soften with Manuka honey 20+ (available from Holland and Barrett) or a natural child cough syrup (note that there is no xylitol!). Given that one of my dogs has just fallen ill from the vaccine, I will not be vaccinated. Please note that a dog pension often demands that a dog be vaccinated against kennel cough.



Leptospirosis is a global condition in humans and animals and is caused by different types of bacteria belonging to the leptospira group. More than 200 different types are distinguished. Dogs are prone to about 20 species. Weil's disease is caused by leptospiren from the serogroup Icterohaemorrhagiae and usually concerns the serovars Icterohaemorrhagiae and Copenhageni. Leptospiren live in the kidneys of their natural host, often without making them sick and being excreted through urine. Contamination occurs because the dog comes into contact with the urine of infected animals. This may be by licking urine or licking genitals of leptospirosis infected dogs, swimming in and/or drinking water where rats live. Favorable conditions for leptospiren are lukewarm, still to low running water. The dog is the natural host to the serovar Canicola (like the rat that is for the serovar Icterohaemorrhagiae and the mouse for the serovar Grippotyphosa).


Take into account the fact that there is no cross protection between the different serovars and that your dog is only protected from disease symptoms caused by the serovars occurring in the vaccine. And even then there is no guarantee that your dog will not get sick when he comes into contact with the serovar in question.  This is also apparent from the wording in the various leaflets. In addition, most lepto vaccines also contain the excipient thiomersal, which is known for its serious side effects (possibly death arising!). Don't underestimate this even though a regular veterinarian will certainly deny this. A puppy in my area died a few days after the vaccination with L4 and the autopsy report indicated that she had died of very severe bleeding. Blood clotting problems have been mentioned in the side effects of the L4 vaccine. It's very sad when you have to give up your dog at 12 weeks.

Only Eurican no longer uses thiomersal in its lepto vaccine Eurican L-multi. It is also true that ALL vaccines operate only 3 ot 6 months.


When you decide to have your dog give a lepto vaccine (due to the higher risks in the area) it is important that your dog is in the best possible condition.  In addition, spring is the best time to administer the vaccine, taking into account the working time and risk of the incuration of the disease. NEVER give the lepto vaccine together with other (combi) vaccinations! After all, the lepto vaccine already contains several pathogens to which immunity must be built up. A veterinarian may be trying to persuade you to give L4 with the large cocktail (Parvo, Hepatitis, Distemper), because L4 can serve as solvent for this cocktail. However, as solvent, they can also use a physiological saline solution! A veterinarian who is also well known with titeren will certainly not do this!

In summary: consider whether lepto vaccination is really necessary, if so go to a veterinarian who administers Eurican Lmulti, but continue to look all the way for possible disease symptoms.



'Many dogs have antibodies in the blood against Lyme disease. Lyme disease is caused by the bacterium Borrelia Burgdorferi. Several vaccines have been developed, but vaccination is not widely recommended. Most infections do not make the dog sick and dogs respond well to a cheap and safe antibiotic cure. The manufacturer of the vaccine has not yet demonstrated the protection against the disease. Check your dog after every walk on ticks but remember that there may also be signs in your garden! When a tick is removed within 16 hours, the risk of infection is low.



When you go abroad with your dog, it must be vaccinated against Rabies, but it may also be that a vet's health certificate is necessary (look for more information on LICG.NL). Here too, vaccines are on the market that add thiomersal. Only Merial doesn't do this. Of course, the application of the vaccine is not recommended in combination with other vaccines.
