Dog Worming: How to Worm A Puppy or Dog?

Dogs and puppies regularly need to be treated for worms. Intestinal worms and parasites are extremely common in dogs and puppies. Your veterinarian will give you medicine to clear up the situation. Some veterinarians will prescribe a pill that has to be administered monthly to your pet. Worms are contracted in various ways including contaminated soil, mosquito bites, and by eating fleas. Your vet will probably ask you to bring in a recent stool sample to be tested. This is usually done at the puppies/dogs yearly check up.

We have generally wormed our puppies between 6-9 weeks old depending on how their physical strength and development is doing. IMPORTANT: Do not give over the counter worming medicine to a dog that is looking or acting sick. Your dog or puppy should be taken to consult a licensed vet in this case. (Please follow manufacturer’s directions for individual wormers. Deworming history of newly acquired puppies should be obtained to determine whether additional dog worming is needed.) Initiate treatment at 6 weeks of age. For a puppy at increased risk, also treat at 12 weeks, and then monthly until the puppy is 6 months old. Treat mother at the same time.

Nursing Dams Deworming

Treat concurrently with puppies.

Adult Dog Worming

Treat monthly or as recommended by your veterinarian. Also monitor and eliminate parasites in pet’s environment.

Newly Acquired Dogs

Worm immediately: repeat in 2 weeks, then follow above recommendations.

Dewormer Review: Safe-Guard Canine Dewormer

Our favorite dog wormer is the Safe Guard Dog Dewormer. It safely treats against Tapeworms, Roundworms, Hookworms, and Whipworms. This particular product you should not administer to any puppy under the age of 6 weeks. Safe to administer to pregnant dogs and heartworm infected dogs. Very important that you follow the recommended treatment process of administer for 3 consecutive days. All you do is mix the feed granules into your dog’s normal food. There are three different sizing options, so make sure you get the right size. You’ll need a 1 gram package per 10 pounds of dog weight for each dose (see instructions).


  • I was thankful to come across a new, safer, more complete worming method recently and am glad to share it. Formerly I used Strongid at 3, 6 and 8 weeks. This only treats for one type of worm. Panacur or Safe-guard as it is branded to the public protects against all 4 types of canine intestinal worms, plus it is considered an effective treatment against Giardia. It is safe for puppies, adults and nursing mothers. The dosage is per the weight of the animal and is done in three consecutive day increments. All dogs should be done at the same time to prevent reinfection from one animal to another. A recurring treatment should be given at least once during your care of the puppies, though my protocol is 4, 6, and 8 weeks.
    While I have only ever seen roundworms (thankfully – they are gross enough!), there are worms and parasitic conditions that you cannot see or know! This protocol is a cheap, preventative means of starting your puppies on the best start possible. This information is not meant to constititute medical advise. As with any course or treatment for your animal – a licensed Veterinarian should always be consulted.

    PS This treatment, though effective, is not well appreciated by the dogs! It must taste awful. Good luck getting the dose down on the third day.LOL

    • We use a liquid dewormer called Pyran that is given based on the weight of the dog. The treatment is once a week for 4 weeks. Our dogs love the taste and I have never had a problem giving it.
