Lightweight plastic running/ racing muzzles allow your dog to pant freely due to their depth and open basket design making them the first choice for off lead running and activities such as canicross, bikejor and lure coursing.


This style is the original lightweight running muzzle and allows the dog to pant, drink and take treats. 


A keeper strap or muzzle stop can be used to help keep the muzzles in place and prevent the dog losing them.  A minority of dogs may benefit from either the keeper strap or muzzle stop but this is not the norm, we find if the dog is in a well fitted muzzle that allows them to pant then very few will try and remove them, however some dogs may lose a muzzle in undergrowth on walks. .

 Measure the length of your dogs head in a straight line from behind their ear, to the tip of the nose. The muzzles are available 19.5 and 21.5cm long and also come with an adjustable leather strap. 

For dogs that measure 18-21cm you need the 19.5cm muzzle, for dogs that measure 22cm and longer you need the 21.5cm muzzle.



This is important to make sure your dog can pant freely.

The circumference of each muzzle size is measured at the end of the basket where the dogs nose will be  and are available in 26, 31 and 35cm.

Hold a loop of tape at 26cm, 31cm, or 35 cm over the end of the dogs nose to see which size they will need to have enough room to pant.


You will now know what length and depth to order from the list below.If you need any help then click here.

(The length of the basket part of the muzzle is 9cm in all sizes.)

Size 5- length 19.5cm / circumference 35cm

The straps will fit a neck of up to approx 15", if this is not long enough then an extension strap may be needed, they can be found here.


Please note that dogs with a high prey drive or a history of reactivity/aggression towards other dogs may still be able to inflict injuries whilst wearing muzzles especially if they are off lead and not under your close control.
