I went to Walmart earlier today and bought this product. I came home and used it on my chihuahua PeeWee. About an hour later I noticed he was making a choking sound and running around acting very strange. I Googled the product and found this site, Thank God. After reading a couple of the posts I snatched him up, got him into the bath tub and bathed him thoroughly. He seems to be calming down some now but I will be up with him through the night to make sure he is OK. I am so thankful for this site, it may have saved my best friend.
