This muzzle is great, very durable, and all the straps are adjustable. The M4light will not fall off my dog making it extremely safe for training. The padding makes it more comfortable for her to wear as the metal basket does not touch or pinch her nose. The only thing is I should have measured the circumference with my dogs mouth more open which would allow her to fully pant and drink with the muzzle on. I would recommend this muzzle to anyone and I am very happy. For express shipping to Canada it will take 6-7 business days.
