My dog Rambo and Maddie have the Hartz Ultraguard Plus flea collars, Rambo has been twitching, and losing hair. Maddie has been losing alot of hair, and being sick.
Rambo: 2 year old Yorkie
Maddie: 1 year old Golden Retriever
My dog Rambo was born in 1/9/09 in Spring, TX, he was fine then. We picked up Rambo on 4/3/09 in Spring, TX. When he was about to turn 2 years old, he started having fleas. We bought the Flea collar at Walmart in 5/7/11. He started losing some hair when we put it on. My dog Maddie was born on 1/31/10 in League City, TX. We picked up Maddie on 3/15/10. When she was new, she started having Fleas and Ticks. We put on the flea collar, she started losing almost all of her hair! We will take it off of both dogs forever soon and get the K9 Advantage II flea drops sometime soon. I hate Hartz for all the side effects they do for dogs and cats.
P.S: Hartz sucks! I will avoid their products forever!
