Choosing any medication for your pup is an important decision just as with picking a high-quality dog treat. You have to be sure that you do not pick something that could harm your pet.
To help make choosing the best heartworm prevention easier, here are some frequently asked questions which provide some in-depth information.
What is heartworm?
The American Heartworm Association defines this condition as a disease where heartworms live inside the major organs, such as the lungs and heart, in addition to getting into the blood vessels of a mammal.
The worms cut off the blood supply, which leads to serious health problems and eventually death. Dogs get this disease through mosquito bites.
This is a serious condition for dogs because the worms can live their whole life cycle inside a dog’s body. They can reproduce rapidly, leading to a severe infestation. This is why dogs must have heartworm prevention medication.
What ingredients are in heartworm meds?
There is a lot of talk about medications given to dogs and how they could cause adverse reactions.Some people worry giving a dog heartworm medication is damaging to the dog. However, according to Belvoir Publications, experts agree that the risks of not giving your dog heartworm preventative are more serious than the risks of giving your dog the medication.
With that in mind, not every heartworm medication is equal when it comes to ingredients. You could compare this to how not every dog collar is equal even if they look similar. Because of this, you need to know the ingredients in a medication.
Ivermectin and milbemycin oxime are active ingredients in some of the best selling medications. They are generally safe for use with minimal adverse effects. Another option that is safe for dogs is diethylcarbamazine or DEC.
The main issue with DEC is that a dog cannot have heartworm when taking the medication because it could cause death. You also must give DEC every day to maintain protection.
Some heartworm medications may also contain ingredients to protect against fleas and ticks, which could have additional side effect risks.
When should I give my dog heartworm meds?
There are different schools of thought about this because some experts think overuse could lead to resistance.
However, think about it this way: do you only put an ID dog tag on when you think your pet could go missing or do you put it on all the time just to be safe?
The chances are you keep it on all the time as a precaution. You should do the same thing with heartworm medication and use it all year as the prevailing experts recommend.
