How much does a grazing muzzle really limit grass consumption for minis? I use one on my welsh pony and it does limit his intake a lot, probably by 80%. My dry lot is full of fallen leaves and will be for amount a month. It is futile to rake or leaf blow it and then let them out as it fills right back up. So my minis are stuck inside unless they are being worked because they will stuff themselves with wilting leaves. If I got a muzzle would it limit them enough so they could go out on grass for 20 minutes to a half and hour? I really hate to disrupt their diet as they both need dry lots, but I hate to see them inside even though they are content and have "rooms with views". Thanks!
