Listing Description: these heavy duty stainless steel dog muzzles were designed 30 yrs ago for dogs that are used in industrial situations such as meat processing plants and farms in general ; where dogs may have to wear muzzles for their entire working day . as well as depriving the dog from the ability to bite they offer some protection for them when working in tight situations such as yards where they are likely to get knocked around. their ability to drink is unaffected . they are also very suitable for guard and attack dogs that need muzzled for those parts of the day when people esp kids may be around them .wearing these muzzles will alert people to the fact that they are looking at "no nonsense " type dogs. available in 4 sizes , large , medium, small , pup made in nz from 3/16 stainless steel these muzzles should last the life of your dogs . you are buying direct from the manufacturer which means that they are significantly cheaper than previously but the time to buy is now as when i make the next batch the price will inevitably increase due to component cost increases .sorry missed a question in last listing. average weight is 325gm but don't look at that as a disadvantage as i have always found that dogs react better to a positive weight .standard postage at the moment is around $8.20 a tip : measure across your dogs head in a line just behind the eyes and then from that line to the end of its nose so as to give me some idea of head size . please note that if you want to bring a dog for a fitting or pickup a muzzle , our domicile is Clinton not Balclutha as this site insists. price is now $138.00 gst inclusive
