Lynn, for what you want to use the muzzle for I think the metal/leather muzzles are really an overkill. I use plastic greyhound muzzles for a variety of things--to prevent arguments that occur when a couple of males get to playing too roughly and inadvertently hurt one or the other. That kind of things causes fights--the basket muzzles will allow the dogs to breathe and to drink. They are light weight and in the greater view of things, cheap
I also use them to keep one of my dogs who gets way too intent on eating grass (and pulls up big hunks of grass, roots and all and tries to gulp it down. Since I once sweated out a full week of three times a day x-rays for a partial blockage cause by big clumps of grass my dogs don't get to play Dobegoat. Over the years I've had several who wanted to but that first and last experience of a partial block from clumps of grass was enough to convince me.
The ones I like best are made in Italy--called Valla and advertised that way. They are beige and come in a wide variety of sizes. Adult bitches take either a size 7 or 8 and adult males take either 8 for a smaller male and my bigger males have always worn size 9's. I buy them from Ryan's Pet Supply in Phoenix, Arizona. They are online at www.ryanspet.com
, phone number is 800 525-7387. Other online and catalogue outfits carry them but if they are NOT described as muzzles by Valla of Italy they aren't the real thing. There are a number of other plastic greyhound muzzles are say they are made in Italy and maybe they are but if they aren't advertised as Valla--they aren't the real thing.
Prices from Ryan are usually the best--sizes from 7 to 10 are either just under or just over $10 each. Shipping is always the killer so I usually place orders with a couple of friends to make minimum (which is usually around $150)--we order toys, muzzles and occasionally scissors or clippers to make the minimum.
A word of caution--Pet Edge was the first place I found these years ago and while the still carry a plastic basket muzzle it isn't a Valla and doesn't fit as well on a Dobe nor do they hold up as well.
