My dog can sometimes have a sensitive stomach but she's fine with Cazitel Plus. She won't eat them of her own free will (even hidden in treats), but I've mastered the technique of giving them to her quickly and calmly!
I gave my dog 1 and a half tablets for 15Kg weight first thing in the morning. Within 2 hours my poor dog had vomitted all his breakfast up. Now I don't know whether he has been wormed or not.
