Hi, I tried 2 different grazing muzzles now, and today my mums going to stitch more sheepskin on it as its wearing her fur away, only a little but enough for me to consider buying yet another one. My ri has turned her out last week, and would of mentioned if she felt it didn't fit correctly. Any suggestions as to which to buy , are they all the same? Just want our little hoover to be a comfy as possible whilst on her diet.Thanks. x
