An alternative to a buster collar for a dog with a wound on its belly

Our dog took 4 days to get settle with a buster collar then found she could scratch quite close to her wound. We made her pyjamas as an alternative & they are working well.
I used a man's vest and her harness.
NB A buster collar is aka an e-collar or elizabethan collar.

Step 1: The jamas

They are made from a vest with a couple of patches of stitching along the bottom edge to make leg & tail holes. The shoulder straps are cut so that she can get in. I had to make the leg holes quite narrow to stop her stepping out of the hole and into the 'jamas & looking like she was in a sack race.
