By trying to save money and time, I nearly killed my precious Shih-tzu using this product! Teddy Bear only had about 3 or 4 fleas, but they were driving him crazy and I couldn’t find the Adam’s flea spray we usually use. I picked this stuff up at Walmart istead of Adam’s when I saw that it killed fleas in as little as 1 hour. That SHOULD have been a red flag)! Within that first hour he started panting like mad and drooling, couldn’t sit still and scared me to death. I quickly Googled the product and was absolutely horrified to find over 33,000 cases that had even killed some pets! I gave him a bath toget the stuff off and it made no difference. I called my Vet and they said to bring him NOW. He gave him two shots, one was Atropene and the other a steroid to help him stop drooling. Gave me a new flea pill, Comfortus, to give a week later. Not sure now if I will….Took him home and within minutes he vomited a HUGE amount of white foam and was getting more paniky by the minute. Harder panting and profuse drooling, so I called the Vet and once again said get him here now. He gave him charcoal in liquid form to absorb what was in his stomach, we had black slime all over the place! Got him back home and there was not much difference, except that the drooling was less and he finally started drinking water. He still couldn’t sit still and it was apparent that he was totally exhausted. I finally got him to lay on my lap and I just kept rubbing his hair backwards and forwards and as long as I did that he laid there. If I stopped he jumped like he had frogs in him. I have NEVER seen anything like this and I’ve had dogs and cats all of my life! Before I tried to go to bed, I offered him a bone marrow treat which he loves and to my surprise, he ate it!!! My husband said to give him all he wanted since he refused his regular food. He ate about 6 and we went to bed. He still could not lay still and was still panting and breathing fast. I laid there all night with my hand on him. If I stopped rubbing his fur, he jumped all over the bed. Finally around 4 am he went to sleep with only fast breathing. I got up around 7 am and he won’t get a foot away from me. I think he knows how sick he was. My Vet said they have had other cases that were alot worse, but I can’t imagine what I would do if I had lost Teddy. PLEASE, PLEASE, PLEASE don’t use this stuff on your pet!!! It should be taken off the shelf and Sergeant’s should have to pay for all of our Vet bills!!!! That is nothing compared to all of the suffering our beloved pets have endured!!! I will be calling Sergeant’s today with this story. If there is anyone who has questions or just wants to talk about this experience, please lt me know.
