Hello again

I have worked out an answer for you below ...

1. Propylene glycol is used as an inert dilutant in this sort of situation as Ivermectin does not mix with water, so only Ivermectin itself is the potentially toxic factor, but if you gave the regular amount for your weight of dog then there can be no extra risk to Poochy.

2. What you did will not cause your dog nay harm of any sort but it may mean the Ivermectin is less effective given this way, you may want to repeat the dose using Propylene Glycol one week from now just in case.

Also I should be available online for you the next two hours today so please do not hesitate to get straight back to me if your dog's condition changes in any way or you would like to talk things over with me further.
