The thought alone concerns you, doesn’t it? Don’t worry that’s why you’re here; we’ve put together a list of the best dog dewormers for you to consider.

Opening up a can of worms . . .

deworming your dog with the best options

Unfortunately, dogs, just like humans’, contract worms and other revolting parasites from the environment, which can have numerous health implications, both to your pet and to their fellow housemates.

If these worms are allowed to grow unchecked, they will adversely affect the life of your dog and can lead to malnutrition and other health-related problems. It is, therefore, crucial to get rid of these parasites by administering dewormers as part of your dog’s health routine. [1]

Taking preventative measures

Most pet parents will buy dewormers only after they receive a prescription from the vet, or when they have a new puppy in the house. This should not always be the case. Deworming your pooch should be done regularly in order to keep them healthy at all times.

Even if the dog does not display any symptoms of worm infestation, most authorities recommend that you should at deworm your dog at least every six months. [2]

Importance of treating a parasite infestation

Once in a while, life-threatening illnesses can result in a dog plagued by worms. The two most common examples are roundworms in puppies whose immature immune system allows the worms to reproduce in the intestines to such as extent that they can cause a devastating infestation; and some cases of lungworm.

Lungworms [3] can cause coughing and difficulty in breathing, and also prevent the blood from clotting. This can result in unexpected bleeding, and in extreme cases, a dog can die from a sudden brain hemorrhage.

Symptoms of a worm problem in dogs

There are numerous health implications if your dog should have a worm infestation, so knowing the signs of a worm problem is more important than ever. Symptoms include:

  • a ravenous appetite
  • weight loss
  • gastrointestinal upsets (such as vomiting or diarrhea)
  • a pot-bellied appearance
  • and a dry or scurfy coat.

Can dog worms be passed on to humans?

The common dog roundworm (Toxocara Canis), can be passed on to humans [4]. A healthy adult human’s immune system can usually effectively deal with the challenge; children [5] are another story.

If a young child should ingest worm eggs, the larva can move through the tissues. Should a larva end up in the brain or eye, serious complications, such as seizures or blindness can follow.

If you are a parent, then you understand what deworming means, and why it is essential to deworm your children every three months. Puppies are no exception, and you must do the same for them too. Maybe a good way to always ensure you remember to do it would be to deworm both your children and puppies at the same time.

Keep your dog safe and healthy at all times by ensuring you deworm them at least every six months. Take care and we wish you many more happy years with your best friend!
