The most commonly used drugs for treating giardia in dogs are Metronidazole (Flagyl) and Panacur (Fenbendazole). So why don't they work?
We wouldn't want to live without our veterinarians but in this case their tools are lacking so let's talk Giardia (which sometimes I capitalize and sometimes I don't.)
The most commonly used drug is Metronidazole (Flagyl). Drugs.com says
it's an antibiotic yet Wikipedia says its an antibiotic/antiprotozoa.
All I know is that giardia is not bacteria, it's a protozoa. I also
believe if it worked I wouldn't be helping so many people who have put
their dog through the Flagyl treatment two, three or four times already.
And then there are the side effects of the drug. Some of them are scary.
I took these from the human side effects list because how would we know if our dogs were experiencing some of these things? Of course your dog may not show signs of side effects but personally I won't give my dogs anything that might cause seizures. Especially when I know natural healing methods to cure giardia in dogs without any side effects (unless you want to count improved health.)
Note that the drugs used for giardia do nothing to aid the damaged tissue in the gut.
Next we have Panacur (Fenbendazole). This drug is a pesticide used to kill intestinal worms.
Giardia is not a worm. It is a protozoa
As for possible side effects? Diarrhea and vomiting. Because a pesticide is a poison, the body tries to get rid of it. And a dog with giardia has diarrhea already.
Kind of a double whammy on the gut don't you think?
Nearly all of the people I've helped cure their dog of Giardia have given the drug protocol more than once to their dog before they contacted me.
The time range of infection has ranged from 2 months to 2 years before they used this natural approach and finally won the battle. Just remember, curing your dog of giardia can be done with patience and persistence.
The longer your dog has had it, the longer it will take to get rid of it.
