I have a german shepherd spayed 9 yr old diagnosed with grade 3 breast cancer . Breast was removed , margins not clean , so lymphangitic spread . She had a large axillary node , 4.7 X 4.5 cm . I put her on daily fenbendazole 50 mg/kg ( she is 30 kg , so 1500 mg ), vitamins ( dog vits , curcumin , Vit E ).After a week , I increased her fenben to 3000 mg daily and added 0.1 mg / lb ivermectin weekly . In two weeks her node has decreased to 3cm X 2.5 cm measured with calipers . I didnt have the node biopsied , because it most likely was hard and enlarged due to the breast cancer on the same side and needling may spread more cancer cells . DOG DOSES ARE NOT HUMAN DOSES !! So far so good ! She looks great , her old happy self . I think I will continue for 6 weeks , following her node size . Then put her on maintenance . Nothing is written about this in the veterinary literature . The vet suggested a referral for radiation . Radiation would also radiate the heart and lung and probably cost thousands of dollars . I said NO to that . Just an FYI !
