I have beagles. They chew things. They chase things. They eat things. Constantly. And dog breath... no one likes that. This ball is relatively easy to make, and helps to keep their teeth clean.
This is a pretty easy thing to knit.
You will need:
Lion Brand Kitchen Cotton Yarn (I love this stuff. It's also a bit thicker than other cotton yarns. And you need the cotton for this project to help with the teeth cleaning) 3 colours help to actually weave this together, but you can use just one.
4mm needles (this is smaller than the yarn recommends, but this keeps your stitches tight)
Stuffing (or a tennis ball works well... not the regular kind, but the ones that are slightly larger for dogs)
Cast on 10 stitches on 4mm needles
Stocking stitch for 60 rows
Do this 6 times, creating 3 lengths of each colour.
Slip the first stitch on each row which will keep your edges really neat and straight.
