Usually, yes. Most of our styles can be made shorter or smaller, and some can be made larger. Common changes are taking up the length for a short-bodied hound, shortening or removing sleeves, and widening or removing a neck. Each one is quoted, except adding a skivvy neck, which is a set-price add-on: see adding or removing a skivvy.
Email aroo@houndtees.com.au with what you're picturing, your hound's measurements and a photo, and we'll come back with a price. For a shorter length, measure from the base of the neck to the top of the first tail joint, because that's where the altered garment will finish. An altered piece can't be returned or exchanged if you change your mind, so measure carefully.
Turning a long sleeve sweater into a sleeveless one leaves two small seams over the armhole where the sleeve was. On a new order we make the change before it ships, so allow 10 working days. For something you already own, here's how to send it in.
