I completed this crochet Chihuaha yesterday.It does have a tail but you can't quite see it in this picture.
It was my first time crocheting a little stuffed animal. It was also my first time modifying a crochet pattern. It was quite an experience but guess what, I'd do it again! It was fun.
The pattern is a Japanese amigurumi pattern that was translated into English. You can find the pattern here but as mentioned, you will need to modify the pattern and figure out how to add more stitches to make everything bigger. I used buttons for the eyes.
