For sparse and short-coated breeds such as greyhounds, italian greyhound, beagles, bulldogs, dachshunds, whippets, and chinese cresteds, a coat is a must. Their lack of hair makes them less tolerant of cold and they will appreciate an extra layer as soon as cooler weather arrives. Some dogs, particularly the northern breeds like the American Eskimo or Keeshond and double coated breeds such as the Collie or Sheltie, can tolerate colder temperatures without a coat. However, if the weather is bitterly cold or your dog is very old, very young, or their coat is sparser than usual due to a medical condition, these breeds too will appreciate the added warmth.

Dogs are a diverse group - it's one of the things we love about them. From Big-chested bulldogs to the elegant borzoi, petite Yorkies, playful bichons, Labs and Goldens, Shelties and Poodles - there's a size and shape to please everyone. However the variation of body types can make it pretty difficult to fit them for clothing.

Which style ?

Winter wear for dogs can be grouped into three basic styles:

Coats - Coats have closures around the neck, usually a wide strap between the front legs under the chest and there is another closure behind the front legs around the widest part of the chest. Some coats have narrow straps which pass under the hind legs and help hold the back of the coat close to the body. These styles have the most flexible fit.

Jackets - Jackets are similar to coats but instead of a chest strap there are "armholes" for the dog's front legs. There is usually some type of velcro or snap closure on the back.

Sweaters and t-shirts - Just like a sweater for people, these are pulled on over the head. There are armholes for the front legs, some styles have either "sleeeves" or straps to fit over the hind legs also.

Note that different manufacturers use these terms interchangeably.

Measuring for a Good Fit:

In order to get a good fit on a coat, you will usually have to take three measurements:

1. The length of your dog's back, from the base of the neck to the base of the tail. This is the most important measurement and the one used by most manufacturers to determine dog coat sizes.
2. Around the deepest part of the chest just behind the front legs.
3. Around the base of your dog's neck.

So, which to buy?

If your dog has an average build and his measurements are a perfect match to those given for a particular coat or sweater, this is a no-brainer. But what to do if your dog is between sizes? Or if they don't have an "average" body type? Here are some suggestions:

• Read the manufacturer's sizing recommendations. Some list "suggested breeds" for a particular coat or sweater size and style. If your dog is one of these breeds (or has a similar size and body shape) this can help you determine if that particular garment is or is not likely to fit.
  
• If your dog's back length puts him between sizes or he has a very wide or deep chest, get the next larger size.
  
• When in doubt, buy the larger size. A coat that's a little too large is better than one that's too small. As with our clothing, coats insulate better if there is a thin layer of air between the coat and body. A coat that's too tight won't be as warm. If you're handy at sewing you may be able to adjust the chest and neck areas for a better fit.
  
• Because of the placement of the leg holes, some dogs simply aren't meant to wear sweaters or other garments with "sleeves". When in doubt, a coat is a safer bet.
