Bests & Worsts Reviews from Amazon

I started using the Seresto Collar for my 115 lb dog because he had reactions to the Trifexis and Nexgard. The first collar worked great, no fleas for about 7 months. Order another one and was very disappointed, didn't seem to work as well. Ordered a 3rd one because I felt I had no choice since the reactions to the oral flea meds. After about 2 weeks after using the 3rd one, I noticed some neurological problems. He was weak in the rear legs, lethargic, had a head tilt to the left and unable to control his BM. At first I thought it was his age, he will soon be 12 years old. I removed the Seresto collar just to see if it was a reaction. I gave him a bath with Dawn dish soap to remove any of the chemicals from the Seresto collar. After 12 hours, he was much improved, after 48 hours he was almost back to normal. I just called the Bayer Company to report what had happened and the rude woman on the phone told me that there was NO WAY the Seresto Collar caused any of the symptoms. Almost like she was shaming me for blaming the collar. Be very careful if you decide to use this collar. I have been searching the internet to see if others have had this problem, there are a lot of the same stories out there, not just mine. BEWARE almost lost my dog with this collar and Bayer will not listen, so guess I am out all that money as well. Google Seresto Collars and hang on for all the nightmare stories.
