I have a one year old mini lop called barney. Last week when i let him out for a run around i noticed his back left leg seemed to be dragging the floor slightly. I took him to the vets and they gave me Lapizole and Loxicom. The vet said it could be a parasite!. I have given him his 5 days of Loxicom and he is on day 3 of Lapizole. Barney is eating and drinking but looks just pitiful when he is out of his cage. He doesnt seem to let this stop him moving around but it must be uncomfortable for him. Has anyone else had this problem with their rabbits?
