What Are Dog Worms

There are numerous parasites for which your canine companion provides the perfect host. Some, like the sarcoptic mange mites, fleas and ticks, are external, but the ones on the inside, like dog worms, although not as easily noticed, can cause serious health issues, weight loss and even death.  

Did you know; Almost all new-born puppies are born with worms

Types of Worms That Affect Dogs

It’s super important to know what type of worming treatment you’re going to need for your canine companion.



Almost all puppies need worming and suffer from roundworms at some point during their lives; there are two types Toxocara Canis and Toxascara Leonine, one of which can also cause problems for humans as well as your dog.


Hookworms can cause some severe health issues in your puppy and, in some instances, can be fatal. More common abroad, these nasty dog worms can be found in moist wet environments like beaches and riverbanks.


Whipworms are again quite common and can affect pups of any age. The eggs can survive in the environment for several years and can be contracted either by contaminated foodstuffs, water or soil, or infected faeces from other animals.

What about Lungworm?

Lungworm is becoming increasingly common in this country and can make your pet extremely ill; in fact, 9% of dogs with a heavy infestation die.

The larvae are found in slug and snail trails and there are several hotspots in the UK; where the risk is much higher, visit the kennel club’s website, which has a comprehensive guide with everything you need to know about Lungworm and prevention. Symptoms include weight loss, breathing difficulties and general sickness.

Common signs of worms:

  • Noticing the worms in stools or vomit
  • Pot-bellied appearance
  • Sickness
  • Diarrhoea
  • Loss of appetite
  • Dull coat
  • Weight loss
  • “Scooting”
  • Lethargy
  • Pale gums 

What’s the Correct Dosage

When administering worming cream or tablets, getting the dosage correct is vital; this will depend on your dog’s weight, which can vary depending on age and the amount of exercise it does daily, so don’t guess!

The dose for large dogs is different from kittens. Worming treatments can cause side effects, so it essential to get it right.

Sneak Them Into Your Dogs Food

Most worming products come in pill form, they are often flavoured in an attempt to make them more palatable and some pooches will snaffle them up no problem.

Alternatively, if Fido is not keen, you can hide them in a small chunk of cheese as a treat. Covering them with a coating of peanut butter or ham can sometimes work too. What dog wouldn’t eat that! 

If you have a dog that dislikes swallowing pills and is hard to fool, you may have to place the treatment directly into the rear of his mouth and hold it shut until he swallows it down.

How Often Should You Worm a Dog?

Always read instructions carefully as some worm medication needs to be given whole, some on an empty stomach or a specific amount of food, some are a single dose and some need to be repeated.

Here’s the kicker

It might seem obvious, but it is vital to ensure your dog has swallowed all the de-wormer and doesn’t spit it out when you’re not looking; pets can be sneaky.

Many worm medicines for dogs and cats recommend a course of treatment every 3-6 months, so your pup is not re-infected with dog worms. However, the frequency of treatment depends on several factors such as lifestyle, age, weight and environment. for example, puppies need a different course of treatment to cats, kittens and large dogs.

Puppy Schedule: When to Worm Puppies 

  • Puppy worming starts from the age of 2 weeks, then fortnightly until they reach 12 weeks of age, then monthly until six months old; after that, every 3-6 months will keep worms at bay. The best puppy and kittens wormers are excellent prevention against worms which can be fatal in puppies.
  • Working pups, which mix with birds and other animals, those which like to scavenge, who spend a lot of time in or near water, live in households with young children, or live in areas where there is a higher risk of picking up certain types of parasites may need worming more frequently or more effective treatment.

If you have any queries about tablets or worm solutions, give your vet a call and discuss any worries. They will answer any questions and discuss the best treatment for your individual requirements.

Possible Side Effects 

Most dogs and cats suffer no side effects after de-worming, from either worming cream, syrups or tablets; however, it helps if you know what to look for.


Your dog may throw up after being wormed; this is nothing to worry about, especially if they have a significant infestation as the little blighters need to be expelled somehow. Although it can be disturbing to spot worms in your dog’s vomit, it means the worming cream or tablets are working until the next treatment.


This is extremely common and is perfectly normal. This is because the worms being eliminated from the intestinal tract by the treatment causes inflammation, leading to poor Fido getting the runs. This is nothing to worry about unless it lasts longer than 24-48 hours; just make sure your dog is drinking plenty.

What to do if they are poorly?

If your dog vomits after worming or has an upset tummy, it is a good idea to wait for 12 hours then feed bland food such as boiled chicken, white fish and rice for a day or so until things get back to normal. If you are concerned about your dog after any parasite treatment, consult your vet. For more general tips on dogs needs, it’s here.


  • Always read the instructions carefully
  • Keep fleas away (they cause tapeworms)
  • Make a note in your diary when the next prevention treatment is due
  • Store away from pets and children
  • Practice good hygiene
  • Contact your vet immediately if your pet becomes ill after using worming medicine.

Alternatives & Other Effective Treatment

1. Syrups & liquids

Liquid dewormer for dogs has its own pros and cons as well as price points. We did an extensive review of Beapar worming syrup, which turned out to be a great worming option.

2. Natural products

There are many commercial worming products that get rid of worms effectively, but did you know there are natural alternatives too. As your furry friend needs worming throughout his life, some people worry that the ingredients in worming drugs may cause damage over a long period of time or nasty side effects.

Therefore they mix it up with FOOD GRADE DIATOMACEOUS EARTH, pumpkin seeds, fermented vegetables and herbs such as Tyme, which is good for hookworms; these are low price ingredients that can be added to dinner or a treat and act as excellent prevention.
