at what age is it ok to start giving ivemec and zimectrin? I have 1 that is 6 months and 2 that are almost 4 months old.
you can start at 4 to 5 months... Ivomec has 1% ivermectin and Zimecterin has 1.87% ivermectin. Mainly used for heartworm prevention but can be used for ear mites.
If a 50 lb. dog needs a 1/2 a cc of ivomec then it just makes sense that slightly over a 1/4 cc would be enough when using Zimecterin. A little extra will be ok but not much more.
There are other wormers out there for intestinal worms that are way better than Zimecterin.
