Please note this important correction.
In the pull-out poster "A Practitioner's Quick Reference to Selected Parasiticides for Dogs and Cats" that accompanied the August 2013 issue, please note in the chart for dogs that Vectra 3D (Ceva Animal Health) is also effective against Amblyomma americanum (Lone star tick).
We regret any confusion this may have caused. Download a corrected PDF of the poster by visiting dvm360.com/ParasiticideChart2013.
