it's important to know the size of the muzzle to take first.
I don't think you can get it online.
I will go to prague within 10 days and I have been requested to buy a couple.
If you let me know what size more or less your dog is (is he adult or will he still grow?) maybe I can take back one more.
The cost is very little (max 4-5 euros) but it will be useless if it's too big or small.
However i confirm it's really excellent.
