Hi Shawna-

Do you know what the average length of time to clear the infection was versus the length if time using Immitricide? I know when we used the Immitricide the dogs came up negative in typically 6 weeks after treatment. One was still weak positive at 6 wks but came up negative at the next test which I believe was 6 wks after that.

The problem I see with Ivermectin is that it would appear that some folks dogs are getting infected while taking it.
