Hello. My 6 month old toy manchester terrier absolutely HATES putting his feet on wet grass. The last week here it has been raining and kind of chilly every day, and it was a struggle to get him to go from the sidewalk onto the grass to do his business. Now it's gotten to the point where I can't even get him to go out the door. He plants his feet on the ground and refuses to move. I try luring him with treats but that no longer works, he just stands their shivering. I don't want to just drag him around of course, so what can I do?
