It is not uncommon for dog puppies to house parasites in their body at birth. But nevertheless, these frequent intestinal worms in the offspring can be dangerous for the vulnerable neonates. Occasionally, the pregnant dog herself transmits the parasites to the puppies during pregnancy or subsequent lactation. This explains why you should go to the veterinarian soon and start proper deworming treatment. In addition, hygiene is essential to fight worms.

"Deworming is essential for our health and that of our puppy," explains the Madrid Association of Pet Veterinarians (AMVAC). In case of suspicion that the puppy has parasites, it is essential to visit the veterinarian.

Earthworms and had They are two types of frequent intestinal parasites in dogs, which also affect puppies. The fundamental difference between these worms lies in their form. While worms are round worms, shaped like a cord, tapeworm is a type of flat worm, more like a ribbon.

Despite their different physiognomy, both are harmful intestinal parasites, which reach the digestive system of the offspring with the same intention: feed on the food that the small and vulnerable puppy ingests.

The organism of an infected pet reacts with virulence to these visitors of its intestine. Among the signs that can warn that our dog hosts parasites, are diarrhea and vomiting. At other times, our dog may suffer annoying flatulence or constipation problems. Earthworms and tapeworms cause, at the same time, a generalized loss of health in the puppy.

The worms are transmitted from the dog to the puppies

Sometimes, the mother transmits these harmful parasites to the pups during pregnancy or subsequent lactation, through breast milk, if the dog is infected.

A pregnant bitch You can transmit your parasites to the puppies that grow inside. Although the best option is to prevent, especially when the dog waits for puppies, it is not always time to fight intestinal worms.

"Prevention is the best strategy to prevent infection by internal worms in a pregnant dog," says veterinarian Diana Contreras. In his opinion, it is also important to increase parasite controls before crossing the dog and strengthen the frequency of the usual deworming treatment.

When to start deworming a dog

In the case of puppies, we must deworm them frequently. It is usual to perform a treatment of internal deworming with medication by drops (external is not necessary because when not going out to the street they cannot take ticks or anything similar) after 20 days of life, approximately. Then the operation will be repeated every 15 days until the dog turns 2 months old. In this cycle of deworming we will have given our puppy between 3 and 4 doses. Some veterinarians prefer to continue at this rate until 3 months of age, follow the advice that yours gives you well and commit to complete all the shots, it is very important!

Newborns are more vulnerable to all types of infections, so deworming is done so often during the first few weeks. If you want you can take your puppy to deworm the veterinarian, but it is not necessary, he will give you the right products and will indicate the necessary doses, you can do it at home.

The first dose to eliminate the harmful worms inside the dog's breeding body is often administered when the puppy has complied around the two weeks old. However, often, this first shot is not enough to end the infection, since the larvae of the parasites can be very resistant to medications.

This explains that, although adult worms have been removed, it is common for eggs laid do not delay in hatching and the parasites manage to colonize the puppy's body again and the shot must be repeated. "Internal deworming against nematodes (roundworms) and cestodes (tapeworms or flat worms) is generally done every three months," they explain from the Madrid Association of Pet Veterinarians.

From two (or three) months of age, we can continue using the same product, but we will vary the dose depending on its weight. Do not worry! The vet will know how to guide you during the process. From that moment, the dog will have to be dewormed internally every 3 months, until he is one year old.

Once you have turned one year old, we will drop the drops and the dog will start taking an antiparasitic treatment in pills or pasta, like any adult dog. The pace will remain one shot every 3 months.

Deworming a dog internally is as important or more than doing it externally. Both processes are parallel and important, but internal parasites have an extra danger: they can be there and we don't see them. And they can cause serious intestinal diseases that could even be spread to everyone who lives with it.

Deworm the dog puppy

According to data from the Council of Veterinary Colleges of Catalonia, 90% of puppies have intestinal worms that can cause digestive disorders. A puppy that is not dewormed can suffer disease and delay its normal development. But it can also infect people living with him hydatid cysts. These are clusters of liquid where the parasite's eggs inhabit.

After this first time, the deworming calendar A puppy varies according to the animal's lifestyle, health status and type of antiparasitic products used, but will continue throughout life.

The deworming calendar of the puppy varies depending on whether it lives in a rural or urban environment

The veterinarian will not apply the same deworming guidelines with a puppy that lives in the city and with another that lives in the field. The latter is more exposed to the spread of parasites from other livestock animals, such as cows or sheep, as well as other dogs, so deworming will be more frequent.

The usual periodicity to deworm the dog ranges from 30 days and three months, exceptions apart.

Orientation calendar to medicate dog breeding

The next calendar is an indicative model which may be subject to changes and variations that the veterinarian considers appropriate with each dog:

Puppies between 21 and 30 days. In this vital phase of the puppy, the usual thing is deworm with a syrup or paste. The reason is that it is still nursing and does not easily digest the product in tablet format. At this age, antiparasitic products that kill both adult parasites and eggs are recommended.

With a month and a half of age. Deworming is recommended before the first vaccination.

The vaccines should not be applied in a dog that is not dewormed. The reason, according to veterinarian Ana Cameno, is that a dog full of parasites does not have the organism prepared for the vaccine to be effective.

"The protocol involves first deworming the puppy, do a stool test later and finally, vaccinate, once it is free of parasites, "he explains.

The following deworming would take place at two months of age of the puppy and another one with three months.

Between three and six months old Another application will be necessary if the dog is more likely to get parasites (lives outside or in the field). In this case, deworming is carried out on a monthly basis, so that it coincides with rabies vaccination. This injection is applied around six months.

From six months, the frequency of deworming of the dog puppy can be monthly or quarterly, as explained, depending on the area where the animal resides (rural, urban or in a residential area).

There are precautions that should be taken into account and with the veterinarian. When dogs coincide in the same park and there is a greater risk of infection, as is usually the case in cities, canine doctors recommend monthly deworming.

On other occasions with less danger of contagion of parasites among dogs, it is usual for the periodicity of deworming to be quarterly.

Exceptions in puppies and adult dogs

Females that are going to give birth. It is convenient to deworm them at the beginning of the heat and about fifteen days before delivery (at 45 days of gestation). A pregnant dog can transmit the parasites to the fetuses through the placenta.

The external deworming of the puppy

The external deworming of the puppy is mainly preventive. Products such as pipettes, collars to fight fleas and ticks are used.

Then, you should start the vaccination schedule when the veterinarian tells you.

Why do you have to deworm the puppy first and then vaccinate?

In this way, and especially depending on where you live, the risk of suffering from the presence of external or internal parasites is greater than that of contracting diseases. For this reason, veterinarians always recommend deworm first and then start the vaccine schedule for puppies On the waiting time between the administration of the antiparasitic and the first vaccine, it will depend on the product used, so it will be the same veterinarian who tells us when to go to vaccinate.

However, external parasites are not the only ones that affect dogs, since they can also be harmed by internal parasites, present in both natural and urban environments. For this reason, despite residing in a city, to prevent and combat the presence of internal parasites veterinarians recommend monthly deworming, especially in cases of risk such as families with children or the use of garden areas for the walk of their pets.
