I made this little guy for a baby. I modified the pattern from Selena K's Aquarias Kitten to post here (with permission) to make him a dog. I also made a couple other changes to the arms and muzzle.

To secure the eyes and nose for the baby to not eat them, I also sewed the buttons with needle and thread.

On my dog, I made the tail too long but didn't feel like remaking it, so for posting the pattern I shortened it.

The original Aquarius Kitten pattern:

Where I got the ears idea, changed a bit.

Any yarn will do. I used four different colors.
One main color for the body, a second color for the paws, and then a third and fourth color for the collar with tag.

F-5 crochet hook (3.75 mm)

Polyester Fiberfill

Yarn needles

Needle and black thread

Three buttons: two for eyes and a black one for the nose

About 8 inches I think? I already gave him a way.

I made the stitches tight so it wouldn't slowly die from the abuse of a small child.
