Over the gauze or foam bandage-layer, put at least 3 wrap-layers of vet-wrap - it doesn't stick to skin, hair, or feathers, only to itself, & doesn't leave a tacky residue, either. U just stretch it slightly, to make it cling. // Vet-wrap is reinforced with fine, tough threads, is much tougher than any ordinary bandage material, & will stand up to the use & abuse of that missing dew-claw space.
If he's tempted to mess with them [lick, nibble, groom], i'd add a footless SOCK over the vet-wrap, constructed of Ace bandage, put on from the bottom up [ankle toward knee]. Use safety pins
that go all the way thru to the underside & back up, to secure it top & bottom; the 4-inch wide Ace-wrap should B fine - put yer HAND under the Ace bandage to prevent him being stuck by the pins, when U insert them!
There's no dewclaw there anymore, but the dog will instinctively lay his leg down when he needs it while running, so it needs protection, or he'll tear the fragile new skin. // I'd keep an Ace wrap on them, for at least 3-weeks from the day they were removed.
I know some breeds want them removed from the forelegs [Dobes, for instance] for cosmetic reasons, particularly to show - personally, as we know that dogs use them functionally, i don't take them off... but then again, i don't own a Dobe that i want to show, either.
Dogs use them as thumbs to hold objects for chewing, & as traction cleats on tight turns - BCs are frequently filmed in agility with both forelegs clamped to the soil by the dewclaws, as they accelerate into a turn.
