I have a 1 year old 56lb Golden Retriever lab mix, I have him on Frontline Plus as a preventative as well as Intercepter for heartworms. The Frontline Plus has been pretty effective as a preventive for fleas but he still gets a number of ticks on his coat. We will be out hiking in the woods for hours more frequently now with the weather getting nicer. I have heard that the Seresto Collar is really effective in repelling ticks which is my biggest concern with the area I live in. I was curious if it is possible to combine both the Frontline Plus along with the Seresto Collar (only if its safe), or if you would recommend one over the other.
