Dear Maryta,
Thank you for your service. I will send a photo as soon as my dog gets used to the muzzle. I am still training him. Though as far as I see the muzzle is comfortable. It is not firm and hard as most of the muzzles I've seen before. My dog is also not the breed that you expect to wear a muzzle for aggression.
My dog just needs it for his addiction of balls. When he sees a rolling ball he becomes a really loud dog and looks like crazy. It becomes even more tough lately. Thus, if I wish to let him out he has to be muzzled. I will send his photo for you soon.
