This morning I found an ascarid in a pile of muck. The horse is 13 years old last wormed on Dec 21st with ivermectin and praziquantel. . (Last time I saw ascarids was when he was 3 years old, worm counts kept coming back at less than 50 yet he had a wormy belly so after seeing them I dosed him.) He has a very elderly companion body condition good for his age but not a lot of fat. I am minded to give them both moxidectin as this will also treat encysted red worm . Is the old one too old for this will it be too harsh for him?advice please.
