Pet's info: Dog | Basset Hound | Female | spayed | 45 lbs
I bathed my 10 year old basset hound with hartz ultrgaurd pro. It contains Phenothrin and has many complaints with serious side effects. The recommended dosage was 3 tbsp for 31-45 and 4 for 46-60 lbs. My dog is on the 41-47 range and I used roughly 4 tbsp. She slept all day and hasn't shown any lack of appetite or symptoms in the 20hrs since bathing. Should I be worried with the reports of fatal symptoms? Is there something I should do preventatively when I get off work today?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If you followed the label instructions then the risk of side effects are rare. I would assume you would have seen them by now. The product wouldn't be on the market if it wasn't safe. There are sadly no medications on the market that are 100% safe, everything has reported side effects. My only advice is to avoid flea and tick dips and sahmpoos. Use a good preventative like the oral flea and tick medications: Nexgard, Bravecto or Simparica or the Seresto Collar which lasts 8 months. I wish you and Baylee the best!
