I used Hartz Ultra Guard on my dog about amonth ago – within a few days she was lethargic, had extremely sensitive skin and began losing hair. After about 7-10 days her hair was coming out in clumps – I bathed her daily for three days and now (about a month has passed) the hair is beginning to grow back in. She was completely bald from her rear end to about midway up to back including back legs. Also the around the neck area in which I applied the drops was bald – No one will ever convince me that this WAS NOT a result of the Hartz medication – is there any recourse to remove this product from being sold? My God, animals are dying from this!
