Dog sweater - first fitting

This is the cabled sweater from Judith Swartz's Dogs in Knits - before the sleeves and ribbing. I used Brown Sheep machine washable worsted and I'm surprised at how soft it is.

It's been getting cold at night here and I'd like to knit robes for the little Lears - similar in shape to Lucinda Guy's versions. I'd like them to look like they are from the original stage production of Peter Pan - jewel tones, cables, mother of pearl buttons, appropriate in the nursery and in battle on deck. When taunted by pirates, one can say, "This isn't my bath robe, it's a very long sweater my mother made me."
