About 18" of snow on the ground. All small dogs take notice!
Cats, too!
Having never lived anywhere except Texas, Oklahoma, and Louisiana, I am not sure I could ever get used to the harsh winters the states far north of us see every year. I would yearn to see the real ground - not freezing cold white stuff day in and day out.
But then, all ya'll prolly couldn't tolerate our cold, dry, windy winters, and our hot, dry, windy summers. :)
P.S. Forgot to mention, though not a small dog, one of my dogs is white, and if he got too far away from me when it did snow here, I wouldn’t be able to see him! :)
