My baby was killed not even almost 9 months ago. I had used the Hartz ultra guard plus flea & tick spray. The reaction she had was heartbreaking. I’m still upset and recovering from her death. She was only 7 years old. She immediately had a seizure from the spray. She recovered but not even 2 weeks later had back to back multiple seizures. Nothing had ever changed from when she was born; the only new thing used was the flea spray and she had a life ending reaction. I had to end up putting her down due to the state she was in and I’m still emotionally damaged from losing my lil babe that was apart of the family. The photo is her a few weeks before this happened. She was healthy and nothing was wrong with her. I urge all to not use this brand for your dog or cat at all.
