I put the Sergeants Gold Flea & Tick Drops on my dogs on Sunday, July 25, 2010 and they became very sick. I spoke with my vet on Sunday night and he said to keep bathing them and give them Benadryl and just keep an eye on them. Both of the dogs had bloody stools and had thrown up most of Sunday evening and night. They were feeling a little better on Monday night but Tuesday morning they both started shaking their heads uncontrollably every time they would stand up to walk. My youngest dog is 3 and he is normally a very social and hyperactive dog, he will not come out of my sons room and lays on my son’s bed under the covers and hides. His personality has done a 360, my old dog is almost 10 years old and she is very lethargic. This is insane that I was able to buy this product and endanger my family members, we think of our dogs as a very big part of our family. Is there anything we can do?
