My Chi's were born 4/6/15. I have two and I know I NEED to start house training right away. They sleep in a crate (good size, fits blanket and puppy pad). But Im having a hard time starting a bathroom routine bc I keep saying to myself they are too young. I KNOW they cant hold it long but when should I start. I want them to go outside but they go crazy shaking when I put them on the grass. Seems they are too scared.
