That's looking better!
Ok. Is that his "back toe" ?
Don't wrap the toe to the foot with your vet wrap. Hard to explain! Apply your SSD, then apply your gauze, you may need to put a tiny roll or folded piece of gauze in there to help separate the toe. Let your gauze help "spread out" the toe or fill in that gap if that makes sense.
If I'm doing toes, I cut my vet wrap into longish thin/narrow strips. I start at the base of the toe, wrap out the toe, then back in. Since this is the back toe, when you get to the foot pad, go across the foot pad and come up between one of the front toes, then you can go across the top, under the back toe and up the ankle. Does that make any sense at all?
Even if I'm just doing a toe, the whole foot and other toes usually end up getting wrapped individually, especially that darn back toe because I'm pulling it up. My strips are narrow, so I end up with layers. Not like a huge stack of wrappings, just layering them until I get it how I want.
If you have a helper, that's even better. I do this by myself usually, so if you are alone in doing this, have your strips already cut.
Don't wrap so tight that you can't get scissors in there to cut the wrappings off. The way I wrap, there's usually no way I can "unwrap" the dressings, I cut them off.
