Made to measure 4 legs sweater fleece with regular sleeve

What is the difference between the regular sleeve and the raglan sleeve. This model, the regular, is more tight on the body, I can do longer sleeve too. 

Made to measure is really made with the measurements you will give me from your dog or your cat. This is perfect if you have an animal with irregular size, like a bulldog or greyhound. 
Refer to the image to see what measurements I need.

Be careful to take the measurement right. If you had some extra without telling me, you risk having some place too big and your dog might loose it. The best is really taking the measurement perfect on your dog and then tell me if you want something more loose, or if your dog is still growing.
