I would like to make a sweater for my Chinese Hairless Crested. Its been really cold and snowy here in Ohio, and he wants something nice and warm. He weights about 9lbs. Thanks!
There are a bunch os dog things listed here, I bet you can find a sweater you like.
Most patterns for dog sweaters are by measurements not weight. There are dozens of patterns. Here’s a few smaller ones you can see if they work or you can work with them. See the link Marilyn posted for lots more.
