Puppy Deworming Schedule

After 7 years of experience, much research and observation I have come up with the ultimate puppy deworming schedule that has helped my clients over the years to ensure zero worm infection. Here is the puppy deworming schedule to follow and enjoy.

1st Deworming Session: At 2 weeks of age

Your puppy’s first deworming session will start as a newborn 2 weeks old. Worms can often transfer from mother to puppy, causing severe worm infection. This first schedule is extremely delicate and important as your puppy has an extremely weak immune system and the infection.

2nd Deworming Session: At 4 weeks of age

To eliminate any newly developed worms you need to repeat the deworming session again at the age of 4 weeks. This will also aid in eliminating any remaining parasites from the previous treatment.

This session has also significance as your puppy has yet not developed their immune system and has been still drinking mother’s milk.

3rd Deworming Session: At 6 weeks of age

As your puppy has now moved from mothers milk to puppy food and gained some mobility it is time for another round of deworming at the age of 6 weeks.

Although your puppy has now developed a little better immune system yet they are extremely vulnerable to worm infection and its severity.

4th Deworming Session: At 8 weeks of age

At the age of 8 weeks now your puppy is much more independent and has a much more active life. This active life comes with increases in risks including more opportunities for worms to attack your adorable pup.

Therefore do ensure proper vaccination accompanied by a deworming session to give their healthy happy l;ife a little boost.

5th+ Deworming Sessions: At 1+ Year of age

With time your puppy will develop a much stronger immune system. You may not need as many frequent deworming sessions as before. However, ensure to continue mandatory deworming sessions every 3-6 months to ensure your puppy is not under attack by any types of worms.
