It took me a long time to write this review because cancer does kill and you cannot blame on something you tried. But I later read on earth clinic or the facebook group for this med that fenbendazole isn't recommended for dogs that have kidney issues. Schnauzers are prone to kidney problems.
I bought fenben (panacur brand, as recommended by J. Tippens) on 9/19. My dog was dead within a month, on 10/17. I know it has helped PEOPLE but on the facebook group (mycancerstory.rocks for pets) pretty much all the pets are put to sleep after trying this dewormer. And there aren't only schnauzers posted there. I only read 1 story that a dog beat cancer after taking panacur.
I think this medication might help human beings beat cancer, but not pets. Mind you, I was also giving my dog essiac tea internally and cansema (black salve) externally.
Cansema worked fast on literally pulling the tumor out of his paw pad, but the tumor was so big that it would take a while to remove the whole tumor (it was wrapping around his paw, I wrote about it on my post about castor oil and turmeric).
I suspect fenbendazole affected him in a negative way, because how come he had been diagnosed in mid 2020 and he was still eating and walking and after starting on fenben, he lost his appetite and became too weak to go for walks or even poop? He was losing his balance and seem uninterested in everything, even when someone knocked on the door.
I think people should not give this to their pets to treat cancer because the pet cannot tell you if it is affecting them internally.
I wish I had not tried fenben because my dog was still interested in going for walks and walking himself to drink water and eat his food. But I am not angry at his death, he would have passed away eventually, even if it would have been 5 years later. I am glad he isn't in pain anymore. I don't have another dog now.
