It does. It takes longer for Milbemycin to leave the system, and I have read 3 different recommendations. One said to wait 1 week, one said to wait 2 weeks, and one said not to use it at all. I think there was info posted in Losul’s thread about how long it takes the body to elminate Milbemycin. You want to wait 3 times longer than whatever the halflife is, so that there is no more than 1/8 of a dose in the body.
