Life with a new puppy is anything but dull. There’s so much to think about, from what to name and feed your puppy, to housebreaking and vaccination.
And then, there’s the subject no one wants to think about, but can’t afford to ignore... canine intestinal worms.
ALL puppies have intestinal worms – or at least, intestinal worms are so common in puppies that it’s probably safer to assume that all puppies are affected and act accordingly.
How do puppies get infected?
Young puppies are often born with intestinal worms, that are transmitted to them...
Hormonal changes in pregnancy can activate worm larvae that had been dormant in the mother’s tissue for a long period of time. These larvae subsequently migrate through the placenta to infect the unborn puppies. They can also migrate to the mammary glands and infect nursing puppies.
Young puppies are often not brought in to the veterinarian before they are 6 to 8 weeks of age. By then, they may already be actively contaminating the environment.
FACT: In 1996, a survey was conducted using stool samples collected across the U.S. Results suggested that more than 30% of dogs under 6 months of age were shedding Toxocara canis (roundworm) eggs. Other studies have shown that virtually all puppies are born infected with Toxocara canis. (As reported by the Companion Animal Parasite Council)
This is an important concern – especially since some canine intestinal worms can also infect humans (what is known as "zoonotic disease").
Intestinal worm infection in puppies can cause the following clinical signs (among others) in puppies:
In severe cases, intestinal worm infections can even be fatal to young puppies
While all this talk about puppies and intestinal worms may be a little worrisome, don’t let it take away from your enjoyment of your new puppy!
Controlling intestinal worms is easier than you may think. It’s a matter of knowing what you’re up against and what to do to get the upper hand. Here are a few suggestions:
As soon as your new puppy joins your household, take him to the veterinarian for a complete check up and vaccination.
It’s a good idea to bring a stool sample with you, so the veterinarian can test it for evidence of parasites, to determine your dog’s worm burden.
Start your puppy on a regular deworming program, using an age-appropriate broad-spectrum dewormer that is effective against the major types of intestinal worms that infect dogs, according to the following schedule:
Make sure the deworming product you choose meets the following criteria:
Safe-Guard® (fenbendazole) Canine Dewormer fits the bill. As an added convenience, it is available without a prescription at many pet, feed and hunting retail outlets, as well as online.
