I use a dremel only on Gracie. When I showed it to Charlie he sniffed it and when I turned it on for him to get use to the noise he freaked. A lot of noises scare him. I just let it run while I was brushing Gracie and had Charlie runnin around the room. For 25 mins he cried and hid in his crate. I tried a couple other times hoping he's get use to it, to no avail.

I only started needing a helper with Charlie when he reached 5-6 months old. He got too big for me to handle on my own. He hasn't always been held down.
