I've noticed Joe still is suffering with those wretched bot eggs - I am struggling to get them off (they seemed to die down but are now back ) I've wormed him about a month ago (it said on the tube that it covered bot eggs). But, when the vet came out the other week for something else, he noticed the bot eggs and said we'd have to worm him again before winter. Can you "over worm"??? I don't want to just dose him again - any ideas on "when" I should do it? I'm on the yards worming program at the mo - but they've not mentioned worming again. Any ideas?
