Care and advice
Vaccinating your puppy is one of the first and most important steps you can take to ensure their health and well-being. Vaccinations will protect them from dangerous and contagious diseases that could put their life at risk.
Below, we offer a detailed guide on the number of vaccines needed, when to administer them, and why it is crucial to follow a vaccination schedule.
How many vaccines do puppies get?
Puppies receive several vaccines during their first months of life to protect them from serious diseases such as parvovirus, distemper, and canine hepatitis. In general, a puppy will receive between 3 and 4 doses of vaccines in its first few months, depending on its age, health status, and local regulations. These vaccines are not administered all at once, but rather in separate doses to properly stimulate the puppy's immune system. Each vaccine is reinforced with additional doses as the puppy grows. Initial vaccinations are usually given between 6 and 8 weeks of age, with subsequent boosters at 12 and 16 weeks. These doses ensure that your puppy develops solid immunity against the main diseases that affect dogs.

Schedule: When to vaccinate a puppy?
The vaccination schedule for puppies usually begins at 6-8 weeks of age. In this first stage, they are given a polyvalent vaccine, which protects against several diseases at once, such as distemper and parvovirus. Between 9-12 weeks, it is important to administer a second booster dose to strengthen their immune system. Between 14 and 16 weeks, it is common to administer a third dose of the multivalent vaccine, as well as the rabies vaccine, which is mandatory in many autonomous communities in Spain.of the polyvalent vaccine and also the rabies vaccine, which is mandatory in many autonomous communities in Spain. After this initial phase, it is recommended that dogs receive annual boosters to maintain their protection. Depending on the area and your dog's specific needs, your veterinarian may suggest additional vaccines, such as the vaccine against leishmaniasis> if you live in high-risk areas, or the kennel cough vaccine, especially if your dog will be in contact with other dogs in parks or dog daycare centers.

It is important to note that the recommended vaccines and schedule may vary depending on the region, the veterinarian, and the specific needs of the puppy. It is always best to consult with a veterinarian to establish the most appropriate vaccination plan for your pet.
Should I deworm my puppy before vaccinating?
Yes, it is highly recommended to deworm your puppy before administering vaccines. Internal parasites, such as intestinal worms, can weaken the puppy's immune system, which could affect the effectiveness of the vaccines. Generally, the veterinarian will prescribe a deworming treatment before starting the vaccination schedule, ensuring your puppy is in the best possible condition to receive the vaccines.
How many vaccines does a puppy need to go outside?
Before your puppy can go outside and interact with other dogs, it must have received at least 2 doses of the core vaccines, particularly the combination vaccine. This typically occurs around 12 weeks of age. It is important not to expose your puppy to environments where it might come into contact with unvaccinated dogs until it has completed its initial vaccination schedule. Once it has received the necessary doses, it can go outside with greater safety and peace of mind, for both you and your puppy.
What happens if I don't vaccinate my puppy?
If you choose not to vaccinate your puppy, you are exposing it to potentially fatal diseases, such as distemper, parvovirus, or canine hepatitis. These diseases are not only highly contagious but can also be difficult to treat and, in many cases, fatal. Additionally, an unvaccinated puppy can transmit diseases to other dogs and even to people. Therefore, it is essential to follow the recommended vaccination schedule to protect both your puppy and the dogs around it.
Mandatory vaccines for dogs in Spain
In Spain, the only mandatory vaccine is for rabies, except in Galicia and Catalonia, where rabies vaccination for dogs, cats, and ferrets is not mandatory. However, in Catalonia, a decree is being processed that could make it mandatory this same year.
This vaccine can be administered once the puppy is 12 weeks old and, subsequently, it is boosted annually or every 3 years, depending on local legislation. However, it is important to note that some autonomous communities require vaccination against other diseases, so it is vital to inform yourself about the regulations in your area.
In addition to the rabies vaccine, veterinarians recommend as practically mandatory the vaccines against distemper, parvovirus, hepatitis, and leptospirosis, as these diseases can be fatal and highly contagious. Ensuring your dog is up to date with all its vaccines will help you comply with regulations and protect its health.
Vaccinating your puppy is not only a responsible act but is essential to ensure its long-term health and well-being. Following an appropriate vaccination schedule will protect it from serious diseases and ensure it can socialize and go outside without risks. At the same time, following local regulations will help you avoid legal issues.
