I both the Hartz Ultra guard dual action topical for dogs and puppies and applied it about 5 days ago.
The next day I noticed a tuft of hair standing up a bit and when I felt, I thought it was tick. As I looked, I realized it was lump on her skin. I didn’t put it together with the UltraGuard until just now because I thought it was scrape/scab from her running through the bushes…but this morning I noticed 3 more and they are all inline with were the Ultra Guard was applied.
Going to bathe her now. She seems okay but this is outrageous – I think, and hope, I’m one of the lucky ones.
