Why This & Not That: Internal vs External Parasite Control

Mar 26, 2021|

Are you poisoning your dog? Today we are talking about Internal vs. External Parasite Control. Our beloved pups can come in contact with internal (inside the body) and external (outside the body) parasites from a range of places in our everyday environment, so with summer coming, it’s a great opportunity to talk about parasite control and prevention.

There are many brands of parasite control on the market that provide different functions and coverage for your dog. You do not need to get them from a vet clinic, since they are all sold over the counter anyway, but before choosing one for your pup, there are few things you need to look into and ideally understand to make the right choice for your dog and your family:

There are three types of parasite control products on the market:

  • Oral pills which the dog ingests
  • Topical application which goes on the back of the neck
  • Wearable which normally goes around their neck

Understand the product’s coverage and protection:

  • For example, both Frontline and Advocate are topical dewormers, while Frontline is only targeting on killing tick and fleas, Advocate is a broad spectrum medicine that can also kill mites
  • Another example, both Heartgard and Drontal are oral dewormers, while Heartgard is targeted to kill round worm, hook worm and heartworm, Drontal is a broader spectrum internal dewormer.

Understand precautions and side effects:

All parasite control products contain certain toxins that kill or prevent an infection of parasites. How does the toxin work, how does it travel through our furbaby’s body and how long will it stay there are the questions that are rarely asked by pet owners. It’s very unlikely a pet owner would carefully read the prescribing information page of any dewormer, but we think you really should.

Chateau Canine always advises the LIMA approach, that is, using the least invasive method available. This means, it’s best to have minimal toxins while maintaining maximum coverage. We came up with a table to show everyone the parasite coverage in the most common brands on the market.

Here are some Hot Tips to consider when choosing parasite control products:

Hot Tip 1: Consider your dog’s behavior and its living environment. For example, if your pup is picking up poop or random garbage on the street or walking in dirty areas, then it’s best to use a broad spectrum internal dewormer regularly. If you are living in the far north and there are only mosquitos active for 6 months of the year during the warmer months, then you wouldn’t need to do heartworm prevention as religiously during the winter months when all the mozzies disapear. However if you are living in a tropical part of China where the mosquitos are out all year long, then regular heart-worm prevention throughout the year is safest.

Hot Tip 2: Should we be using an oral product to kill external parasites, and/or using a topical product to kill internal parasites? For example, there are a lot of negative reports online about Nexgard and Bravecto. These two are an oral pill that kills external bugs. Let me explain the process: The toxin goes through your dog’s entire system, and then still has enough toxin to accumulate and stay on their skin, then when fleas and ticks bite your dog, the bugs die. For Nexgard this effect last for a month, and Bravecto lasts for up to 3 months. The US FDA has issued an alert for people who are buying these products. Do you think the convenience of these products is worth the potential impact on your dog’s body? Read the US FDA alert.

Hot Tip 3: No need to double up on coverage. Why? Simply, it minimizes the toxins in your dog’s body. For dogs, Chateau Canine recommends Revolution and Drontal for a comprehensive yet minimally invasive solution for parasite prevention and control. Have a look at the table above (highlighted in yellow) to see how well they fit together. Alternatively you can read more about these two products on the Chateau Canine website.

Hot Tip 4: Types of toxin matters. Most of the topical dewormers are a pesticide, it is therefore unsafe for your dog to lick or digest. Additionally, overdosing can result in poisoning. If you have a very young (human) baby and need to regularly do an external dewormer on your dog, then your (human) baby is exposed to the pesticide as well. Chateau Canine prefers external dewormers with selamectin as the active ingredient, this has been shown to not affect the nervous system of your furbaby.

Finally, China is a fun, exciting and interesting place to live. However when it comes to the environment our dogs live and play in, there are many challenges to keep our dogs free of parasites and bugs. Parasites can be picked up by drinking dirty water, a bug landing in their food bowl, their paw walking in soiled grass (which then gets licked after getting home), a mosquito biting them during summer, or all the fleas, ticks and other insects that are around in many areas with trees or bushes near our homes. Being aware of the choices, and taking preventative action is the best way to ensure our pups are healthy, happy and safe in China.
