Silicone Mouth Cover Dog Muzzle in Six Sizes

This is a silicone mouth cover rather than an open basket, made for medium and large dogs and sold in six numbered sizes. It is available in black, red and yellow, and the soft silicone makes it lighter than many hard muzzles, from 2.3 oz (66 g) in the smallest size to 8.7 oz (248 g) in the largest.

Sizing starts with your dog's mouth circumference, which you can measure with a soft tape just behind the nose. No. 1 suits 7.1 to 8.3 in (18 to 21 cm), No. 2 suits 8.3 to 9.8 in (21 to 25 cm), No. 3 suits 9.8 to 11.4 in (25 to 29 cm), No. 4 suits 11.4 to 12.2 in (29 to 31 cm), No. 5 suits 12.2 to 13.8 in (31 to 35 cm) and No. 6 suits 13.8 to 15.4 in (35 to 39 cm). Each size is slightly larger than the range it covers; the inner circumference runs from 8.7 in (22 cm) to 15.7 in (40 cm), and the depth from 3.5 in (9 cm) to 5.7 in (14.5 cm).

Because a mouth cover can limit panting, keep wear brief, avoid hot conditions and never leave your dog alone while wearing it. Introduce it slowly, with treats. Wash with warm soapy water and dry it fully before storing.
