Important Things To Consider Before Buying The Best Dewormer For Dogs
There are some key things to keep in mind when looking for the best dog dewormer. They include:
Types Of Worms
Unless the vet specifically classifies the best dog dewormer as a broad-spectrum drug, you must buy the specific dewormer for each type of worm. The best place to start is by identifying the type of worm infestation your dog has through a visit to the vet and proper testing.
The stool usually tells which type of worm she has, and the best treatment can commence. Do not buy over-the-counter dewormers without having the correct information about the type of worm infestation you are treating.
Age & Weight Specifications
The best dog dewormer has a specific age to administer the drug. Stay away from medications with vague instructions, and always follow your vet’s instructions. Also, make sure you have a guide about the weight specification to administer the drug appropriately based on your dog’s weight.
Most dog parents who overdose their doggies do so because they do not know their weight. They end up giving more than they should per pound of weight. Be sure to know how much your pup weighs, so you can dose him appropriately.
While you may not expect any side effects in deworming, it is always prudent to be prepared for them. The side effects are usually short lived and self limiting, but they can be scary. You may see vomiting, diarrhea, and even dead worms in their stool. In severe cases, your dog may have an allergic reaction which can include seizures and labored breathing. Take her to the vet immediately if these symptoms occur after you’ve administered the medication.
Form Of Medication
You know your pooch best, so depending on her eating habits, choose the dewormer that is most palatable for her. You can choose from chewable tablets, liquids, granules, or powders. Puppies, for example, may easily take to liquid or powder dewormers mixed into their food as opposed to chewing a tablet. Also, opt for flavored tablets if you have a finicky eater so that they can think it is a treat instead of medication.
Who Needs Dog Dewormer?
All dogs need to be dewormed for their overall health. Dogs are unfortunately excellent candidates for worms and other parasitic infestations, because they love to slurp, lick, and gobble up suspicious items in their path. Some of the things they eat are contaminated with parasitic elements, resulting in worm infestations.
The most common worms found in dogs include hookworms, roundworms, tapeworms, and whipworms.
The vet will take a look at your pooch’s stool to ascertain which worms are present and then treat them using a broad-spectrum drug that targets multiple worms simultaneously.
Since all dogs need deworming, it is crucial to know when to deworm your dog at every life stage.
Puppies should be dewormed before their first vaccination. This is why the dosage for deworming pups begins at as little as two weeks for some dewormers to six weeks for others. The medication is given in intervals of two weeks until the pup is 10 or 12 weeks old.
Deworming your pup when she is so young is vital even if she doesn’t go outside yet. Contact with other dogs that go outside can result in a worm infestation in your puppy, and in some cases, a pup already has worms from her mother.
Adult dogs generally need deworming every six months. But if they live in a rural area where they roam around and can eat anything undetected, you should bump up their deworming schedule to every two months.
Dogs that live in an urban area may be less likely to have a severe worm infestation, because they live in more controlled environments. However, they still need to be dewormed to keep them healthy, so stick to the six month schedule.
Deworming a pregnant or nursing mother dog is crucial to not only her health but also the health of her puppies. Deworm her approximately 10 days before she is due to give birth. Continue with the treatment every three weeks for as long as she is lactating to help prevent worms from reaching her pups through nursing.
Always check with your vet about the best over-the-counter dog dewormer for pregnant/lactating mothers.
Why Is Deworming Important?
Deworming is important because it not only contributes to excellent general health of your pooch; it also prevents transference of the parasites to other members of your household, from humans to other pets.
Worms are intestinal parasites which can be transmitted via vomit and fecal matter. Here’s why it’s important to get rid of these little monsters:
Protect Your Dog’s Immune System
Worms can placate existing diseases while enraging others, because they affect the immune system of your dog. They can deactivate some immune system cells. But through deworming, your dog’s immune system becomes more resistant to parasites and some of the diseases they cause.
In most cases, because the worms themselves contain allergens, they end up triggering severe allergic reactions in your dog.
Activate Immediate Response To Vaccinations
Remember when I said that doggie parents must deworm their puppies before they have their first vaccination? Well, that is because parasitic worms weaken the body’s immune system, making it hard for your pooch to respond well to a vaccination.
Combat Worm Infection
Double deworming (i.e. deworming with double or triple the recommended dosage dosage) is the best way to completely combat worm infestation. Dogs are susceptible to worm infestation even from natural tendencies like sniffing at infested fecal matter. And in pregnant mothers, the closer she gets to her due date, the more active the parasites become, so she is vulnerable to significant parasitic infestation at this time.
Unfortunately, a nursing mother can transmit parasites to her pups through her milk. It is important to ensure that even as you deworm your furry friend to get rid of internal parasites, you also treat her for external parasites like ticks and fleas.
Topical treatment options are readily available on the market, ranging from specially treated deworming collars, shampoos, and sprays to a liquid treatment placed at the back of your dog’s neck.
Types & Symptoms Of Worms
Worms can enter your dog’s body when she sniffs, licks, or ingests matter infected with the parasite.
Here are the types of worms you can expect, how they infect your pooch, and symptoms of infection:
Types Of Worms
Roundworms are found in fecal matter. They are prevalent in nursing and lactating mothers, so there is a high chance of being transferred to pups through her milk. Symptoms include a bloated stomach, anemia, weight loss, and pale gums, among others.
These worms eat the host’s food, so she doesn’t get enough nutrients while causing her to have severe diarrhea. They can be fatal in puppies, and unfortunately, they can also find their way into humans with lethal effects. Unless you are using the best roundworm medicine for dogs, the effects could be devastating.
These worms are found mainly in the small intestines of your dog. Hookworms are blood suckers, taking blood from their hosts and causing them to be weak and malnutritioned. The result can be death in young puppies. Symptoms include loss of appetite, weakness, and lethargy, as well as vomiting and diarrhea.
Dogs get hookworm infestations from eating the carcass of an infected animal. You can get infected with hookworms if your dog has them. Also, eating unwashed vegetables can result in hookworms in humans. Your dog will need double deworming to effectively get rid of hookworms.
Heartworms are caused by a simple mosquito bite, and unfortunately, there is no way to tell if the mosquito carries the infection. This is the reason vets advise that you make sure your pet is taking dewormers to prevent heartworms.
The gestation period for heartworm larvae to mature into adult heartworm is seven months after the initial mosquito bite. The adult heartworm makes its way into the heart and lodges in the arteries and blood in the heart.
Symptoms include coughing, lethargy, inability to exercise, and even unconsciousness. Unfortunately, these symptoms begin to manifest only when the heartworms have overcrowded you dog’s heart and lungs, which is why the disease can become fatal seemingly very quickly.
After the initial bite, the dog will not show any symptoms, and sometimes even regular checkups with the vet may not show any heartworm. Because of this, vets recommend that dog owners give their pups monthly heartworm dewormers from a young age as a preventative measure.
You can prevent heartworm by giving your dog monthly deworming tablets, using topical medication that deters mosquitoes, and also using an injection every six months.
You will find whipworms at the junction of the small and large intestine. They are blood suckers as well, and your dog can get infected with whipworms from contaminated soil. Their symptoms are very severe, with your dog having bloody diarrhea and vomiting, as well as severe weakness.
These worms grow exponentially in a short period of time compared to heartworms, causing a lot of damage in a short span of time. Heartworm dewormers are very effective against whipworms, but you can also opt for the usual oral dewormers if you catch the infestation in the initial stages.
Tapeworms are found in the intestine of your dog where they attach themselves and block the intestines. These worms infect dogs when they swallow fleas and lick themselves when they have a flea infestation on their coat. Fleas are carriers of tapeworm larvae which they transfer to the dog.
The symptoms of tapeworms include moving segments of the tapeworm around the anus, in the stool, and even on bedding. Also, you will notice your dog licking her anus a lot or dragging her hind quarters along the floor to minimize the irritation. Another symptom is acute weight loss even though your pet is eating normally.
A shot or tablets are effective in curing a tapeworm infestation. Once administered, the medication destroys the worms, and you will not see them pass through the stool.
While these are not actual worms, ringworms can be treated with a dewormer. They manifest as dry, itchy, scaly patches on the dog’s skin, and dogs get infected from contact with the spores of the fungus that causes ringworm. Cats are known carriers of these spores, so make sure you treat your dog and cat as well as yourself, since ringworms from dogs can infect humans.
The symptoms include itching in the affected area, and treatment can last two months. Oral medication is effective, but you also need to use shampoos and ointments on the skin. Also clean and disinfect her bedding to prevent a recurrence.
In the video below, you can learn how to identify these worms:
A dog suffering from a worm infestation can suffer for years from the parasites unless she is diagnosed properly and put on the correct regimen of drugs. But the great news is that this best dog dewormer review consists of the best solutions that can alleviate the discomfort once and for all.
For instance the 8in1 Safe-Guard 4 Canine De-Wormer (a 3-day treatment), which is the best worm treatment overall, has the capacity to effectively deal with the most common types of worms. It’s also fast and comes complete with a guide to make your work easier.
The rest of the dewormers on this list are also special in their own way and will serve you well if they match your specific needs.
Of course, make sure you do the basics for the best results including getting the timing of the dosage correct and using the best dog dewormer for the type of worms your dog has.
