Hi I have been using the new Seresto collar on both my dogs and some fosters with great success. I live near thick woods full of ticks and fleas I also hike alot with them. Even though our very warm summer I had no problems. What's nice is they last up to 8 months! Similar to Advantix it releases the ingredients slowly over time throughout the entire body. If you have a dog that is in the water alot they suggest replace every 5 months, also available for cats too!
