A reliable and recommended solution for keeping young pups free from multiple worm infections.

The PetArmor 7 Way De-Wormer is designed to treat a broad range of common parasites in small dogs and puppies weighing between 6 and 25 pounds. It targets seven types of worms, including tapeworms, roundworms, and hookworms, which covers many of the usual threats to young dogs. The chewable tablet form is a big plus, as it makes giving the medication easier and more pleasant compared to pills or liquids, especially for puppies. It's safe for puppies aged 12 weeks and older, which fits well with typical deworming schedules. The product advises watching your puppy after dosing to ensure the full dose is consumed, which is a helpful tip to make sure the treatment is effective.

It is recommended to consult a veterinarian before re-treating or for diagnosis, which is important since the need and frequency of deworming can depend on your puppy’s environment and health status. The packaging provides clear dosing instructions by weight, helping to avoid confusion. This product is limited to small dogs and puppies under 25 pounds, so it’s not suitable for larger breeds or adult dogs. While the broad parasite coverage is helpful, it doesn’t cover all possible parasite types, so a vet’s advice remains key.

PetArmor 7 Way offers a convenient, vet-quality option for puppy owners needing a simple and effective way to handle common worm infections in young, small dogs.

Form of Dewormer
A little syringe would be a helpful addition, as it currently only comes with a measuring cup.

The PETARMOR Sure Shot 2X Liquid De-wormer is effective against 4 types of worms—2 roundworms and 2 hookworms. This makes it a suitable choice for comprehensive parasite control in dogs. It's designed for puppies as young as 2 weeks and is safe for dogs of all sizes and breeds. The dosage is straightforward: 1 teaspoon per 10 lbs. of your dog's body weight.

Puppies need frequent treatments at 2, 3, 4, 6, 8, and 10 weeks of age, while adult dogs should be dewormed monthly if they live in heavily contaminated environments, making it a practical option for both young and adult dogs. The product is available in a 2 oz. bottle, which is convenient for multiple doses. However, one potential inconvenience is the need for frequent treatments during the early stages of a puppy's life.

Safety and minimal side effects are highlighted, as it is vet-quality. Always ensure to follow the dosage instructions to avoid any possible complications. If in doubt, consult with a veterinarian. This product is particularly beneficial for dog owners looking for an easy-to-administer liquid form of dewormer that covers a broad spectrum of parasites.

Buying Guide for the Best Dewormers For Puppies

Choosing the right dewormer for your puppy is crucial for their health and well-being. Dewormers help eliminate internal parasites that can cause serious health issues. When selecting a dewormer, it's important to consider several key specifications to ensure you pick the best fit for your puppy's needs. Understanding these specifications will help you make an informed decision and keep your puppy healthy and happy.
Type of ParasitesDifferent dewormers target different types of parasites such as roundworms, hookworms, tapeworms, and whipworms. It's important to know which parasites are common in your area or which ones your puppy is most likely to encounter. Some dewormers are broad-spectrum and can treat multiple types of parasites, while others are more specific. If you're unsure, a broad-spectrum dewormer is often a good choice, but consulting with your vet can provide the best guidance.
Age and Weight of PuppyDewormers are formulated based on the age and weight of the puppy. Puppies have different tolerances and dosage requirements compared to adult dogs. It's crucial to choose a dewormer that is specifically designed for puppies and to follow the dosage instructions carefully. Overdosing or underdosing can be harmful. Always check the product label for age and weight recommendations to ensure the safety and effectiveness of the treatment.
Form of DewormerDewormers come in various forms such as tablets, chewables, liquids, and pastes. The form you choose can depend on your puppy's preferences and ease of administration. For example, some puppies may readily eat a flavored chewable, while others might need a liquid that can be mixed with their food. Consider your puppy's behavior and what form would be easiest for you to administer consistently.
Frequency of TreatmentThe frequency of deworming treatments can vary depending on the product and the type of parasites being targeted. Some dewormers require a single dose, while others may need to be administered over several days or repeated at regular intervals. It's important to follow the treatment schedule recommended by the manufacturer or your vet to ensure complete eradication of the parasites. Consider your ability to adhere to the treatment schedule when choosing a dewormer.
Safety and Side EffectsSafety is a top priority when choosing a dewormer for your puppy. Look for products that are approved by veterinary authorities and have a good safety profile. Be aware of potential side effects, which can range from mild (such as temporary digestive upset) to more serious reactions. Reading reviews and consulting with your vet can help you understand the safety and potential side effects of different dewormers. Choose a product with a proven track record of safety for puppies.
Veterinary RecommendationConsulting with your veterinarian is one of the best ways to ensure you choose the right dewormer for your puppy. Vets can provide personalized recommendations based on your puppy's health, age, weight, and specific parasite risks. They can also guide you on the correct dosage and administration. A vet's recommendation can give you peace of mind that you are making the best choice for your puppy's health.
