    Buyer’s Guide: How to Choose the Best Dewormer for Dogs

    Who Should Buy Dog Dewormer Products?

    It is very common for dogs to pick up internal parasites. Canines love to play in places where all sorts of worms could exist. They don’t do it on purpose; it is just a regular part of a dog’s life.

    Different types of pests live in soil, fecal matter, and other things you might find outdoors. If your dog were to accidentally swallow any of these worms, or even get them from their mother when they were a puppy, then you’d want to get them treated to prevent them from getting ill. Prevention is always a smart idea, but many of these products will control and prevent at the same time.

    All pet parents should be prepared to buy dewormers to protect their fur babies. Pay attention to your dog’s behavior and get them checked by the vet if you suspect that they have gotten worms. Those wanting to avoid them in the future need to prepare for the fact that they will have to have a steady supply of dewormer on hand.

    Features to Consider Before Buying

    Ingredients

    There are a lot of ingredients listed for dewormer medicines. Not all of the formulas used work on the same types of worms. Do your research and make sure that your dewormer contains the active ingredients necessary to kill that type of worm you’re targeting. For example, the medicine should include piperazine for roundworms.

    Parasites Targeted

    Regardless of the dewormer brand you buy, each box should clearly list the parasites that the medicine is targeting. There is no point in giving your dog the pills if they don’t specifically target the specific type of worm that has infested them. Today, most of these medicines target various parasites, however making sure the product covers what you need is a must.

    Number of Doses

    Pay attention to whether your dewormer is in one-day or three-day doses. If you can’t commit to giving your dog the medicine for three days straight, then you’re better off buying a brand where you only have to administer one and forget about it.

    Method of Administration

    The method in which the medicine is administered is also important. Some dogs are very picky, and no matter how much your wrap the pill in deli meat, they’ll find a way to swallow the treat and spit out the pill. Pet parents should know which presentation to give to their pets for the easiest administration possible.

    Side Effects

    The last thing you want is to give your dog something that could negatively affect them. Look through the listed side effects before purchasing a dewormer. Most trusted brands are still easy on their digestive systems and are a bigger benefit to their quality of life with it than without it.

    Like with any medication, please keep a close eye on your dog during the first 24 hours and call the vet if you notice any abnormal signs or side effects.

    Age and Weight Requirements

    Not all dewormers are made for every dog breed. You have to pay very close attention to the medicine that you are buying. It should be specific for your dog’s breed size and weight. Follow all instructions labeled on the box to ensure they are getting the proper dosage.
