Thankfully Flea and Tick season may be over for some of us, but that Indian Summer can be a problem. I started using the Seresto Collar and it works great, I did alot of research and its a great way to protect from fleas and ticks. Last 8 months, if you have a water dog they suggest 5 months. It works just like Advanitix only you don't have all the concentrated chemical in one spot Seresto uses a time released process. Love it check it out http://www.dog.com/item/seresto-flea-and-tick-treatment-for-large-dogs/400317/
