My dog will go anywhere, but snow does take some getting used to. Walk him around in the snow for awhile and eventually they'll learn that it doesn't kill them to go on white stuff instead of green!

The first time Frankie had to go and it was snowy, she would keep me out until she finally found the single patch of grass available.

It just takes time for pups to realize that snow is okay to pee on.

Also, digging out a small, grassy space in your hard can make it easier.

Thankfully I don't have this problem. Especially because living in Pennsylvania we get TONS of snow. The one thing that I do because Maisy is pretty small is go out in my yard and shovel her some paths and a pretty good size area where she can do her business. Even though she loves playing in the snow she will go over to the shoveled area when she needs to go. I'm sure my neighbors think I'm nuts when they see me making all these paths around my yard...but whatever.

Try using on of those "potty rocks" - they are used for potty training and apparently they have a special odor that makes doggies what to go. More info here:

Oh, and this is a place where you can buy it. I'm pretty sure they have them in pet stores as well.

Snow isn't a problem for me, but one of my dogs refuses to go on wet grass. Instead he'll go right on the patio, wherever he pleases. When it gets really ridiculous the only way we've found to get him back in the grass is to cover the patio in food dishes and keep them full, and feed both of them outside where he was going until he stops.

We had this problem with Zena. My dad came up with the idea to shovel a path from the door across the porch and then shoveled a big square in the lawn. I dunno why, but it works.

During the winter, we put the trampoline close to the house then shovel a path to it. For the most part the area under the trampoline is free of snow so Chloe has a large area to sniff out the perfect spot.
