Well we ended up doing the mitaban dip (much to my concern) and one week away from Yodi's last dip he had a very bad reaction (threw up 6 times between 8am and 3pm) and had to have the reversal shot. He was fine, the vet said don't worry about the last dip, and we are now demodex free!!! The only good thing that remotely came from this whole experience is I found out it is SO much cheaper to give all six of my dogs ivermectin daily than to spend over $300 every six months on heartworm meds from the vet. So I am thankful to have found that little fact out! It's once more step at dinner that I am willing to take to save me a load of cash that can now be put toward their savings for any unexpected moment that may happen for them. As we all know fully well, those moments DO happen! Anyways, I just wanted to share the news! We're still watching Yodi's skin and keeping a close eye on it JUST IN CASE. I'm a paranoid mother now, but hopefully we'll be in the clear for good forever!
