excellentI have an 8.5 year old German Shepherd and have used Advocate since I first got him. I find it the most effective and easiest way to ensure that my "loved one" is protected. Some would think it is expensive but you must remember, you are administering with ease a complete cover for your pet. You are not paying for, then trying to administer a few separate tablets to cover the things he may be susceptible too. He is my baby and I want him around in comfort for a long, long, time. Every time he gets a bath - every 4 - 6 weeks, I use a new tube of Advocate on him. He has always been flea free and shown no signs at all of any worm infections.
At Christmas I was given a kitten (oh joy! as if one much loved and spoilt pet isn't enough to look after!) and I started him on the Advocate as well last month. He has had no adverse reaction to it and appears to be worm and flea free!
