Canada PoochSnowsuit - Black - Size 14 (13-15" Back Length)

My dog has a 25" chest and 18" back and 15" height. What size should I get?

If there a hole on the back to hook the leash to?

Would this suit work for a long and skinny, long legged dog (miniature poodle)? I want my pup's legs to be covered.

Is lining fleece?
