Dear Yulia and the team, thank you a lot for this fabulous experience of customer service. Purchase of the muzzle for my German Shepherd was simplified from the very beginning owing to the clear instructions and the video tutorials and the scheme "how to". All your messages were useful and exact, delivery terms are at the top! The muzzle fits excellently, made very well, and my dog wears it without objection. as the hardware doesn't hinder breathing, barking or drinking. Well, it is total success. Thank you all a lot! Well done!
