I have had rabbits all my life and have never previously wormed except once about six months ago I saw worms in one of my rabbits 'Bonnie' who is eleven years olds, droppings. I wormed him and his hutchmate for 28 days with Panacur which they hated but got used to and they seemed to put on weight. Again Bonnie has lost weight and I have looked into worming again but I am wondering if i should worm all of the rabbits. They share the garden with two dogs and a duck (who are all regularly wormed). We have 10 rabbits including one continental Giant that are housed in pairs. They are rescued bunnies so I don't know if they have ever been wormed. I just wondered if anyone could reccomend a wormer or if Panacur is the best? Bit unsure what to do for the best? Many thanks X
