This is a fun, and informative, custom Mini Schnauzer vinyl window decal. Tell people the way it is: I Don’t Need Therapy I have a Mini Schnauzer! While these are great for car windows, they work very well on house windows also. Many Lucky 7 Schnauzer owners use our vinyl window decals to make glass doors more obvious – especially to young Schnauzer puppies that don’t yet quite understand clean (invisible, but hard) glass. Order one for each vehicle, and at least one for a house door or window.
