Each Harris Tweed coat has a fitted and shaped back panel, lined with polar fleece.
'Waistcoat' - One piece of Harris Tweed covers the chest down to the stomach, protecting the chest and underbelly. This can either be in the same material as the back, or in a contrasting colour. This is also lined with polar fleece and joined to the back panel by buttons - 2 or 4 at the chest (depending on the size of the dog) and 2 on the back.
Each dog coat is made to measure, which means a couple of fittings is needed to ensure measurements can be taken and final placement of the buttons/fixtures are right.
A pattern is made for each coat and then the chosen Harris Tweed, coordinating polar fleece, buttons and bias binding assembled into the final coat.
This is the most complex coat to fit correctly, therefore fittings with the dog are preferred rather than a remote order. Usually for mail order coats, as fittings are not possible, a calico pattern is made from the measurements to test that the fit is correct before cutting out the Harris tweed. for this design, this may need more than one pattern to ensure the right fit.
The Harris Tweed is treated with Scotchgard to protect against stains and makes it easier to clean and keep clean.
