Menigital worm

Just a quick post on the menigital worm,I called my vet today to see what was given to Ringo Back in April of 2007 as I can`t locate the papers!!! & it was 1 cc of Ivermectin,2cc of Vit.B,& Baytril.It took awhile but he pulled out of it & now it`s as if he never had it.I always make sure there are no rotten boards in the pen & if they do have boards or things to play on,that they are on a stony area as slugs can`t go across gravel.
