Pet Sizing Guide

Pet Sizing Guide

A handy guide to get the perfect fit for your perfect pet!

Measuring your pet is very important as sizes for clothes can be confusing; remember that sizes cater for the tiniest of dogs, so your ''small'' Spaniel may in fact be an x-large in dog clothing when compared to small for a teacup Chihuahua!  We recommend you measure your pet using the guidelines shown below and choose the size giving the most room.

Important: this is a guide on 'how' to measure your pet. In addition to this page, please ensure you check the product size which can be found on each individual product page entitled 'Sizing Guide'.  This can be found under the product description.  Please check the size on every product you are looking at because sizes vary between styles, so a 'small' in one brand, can be a 'medium' in another brand.

Pet Clothing Measuring Guide

Top Tips:

The 'chest' is a really important measurement, getting it right will mean your pet can move freely without any restriction or without tripping.

If your pet ''freezes'' when wearing a new coat - it could be because their movement is restricted and they need to go up a size.

If your pet is on the cusp of two sizes (or at the maximum of one size), is a little bit ‘chubby’, has a broader chest or has a thick coat, it is often better to choose the larger size. Remember that any pet clothing and especially collars should fit comfortably and snug without any restriction or tightness. 

        It is important to ensure that your pet is happy wearing clothes and that they are supervised at all times. If your pet, especially dog, is prone to chewing - then it may be best to remove any fashion accessories - such as a broach, otherwise, please supervise your pet at all times.

        Pet Collar Measuring Guide

        Pet collars are measured by neck circumference i.e., where the collar will sit. Pet collars, especially for dogs, should be snug with enough room to fit two fingers between your pets neck and the collar. The collar should not be loose enough to slip over your pets head. Collars should also not be so tight as to restrict breathing or cause coughing. There are 2 ways in which you can determine the right size collar for your pet.

        Option 1: measure your pet's old collar (if it's the right size). To do this lay the dog collar out and use a tape measure from the outer edge of the buckle to the hole used to find the right length.

        Option 2: measure your pet's neck. To do this, use a tape measure to measure how you wish the pet collar to fit around your pet’s neck i.e. with enough room as not to be tight but not too loose that the head slips through. A rough estimate is to allow two/three fingers to fit easily under the tape whilst measuring. Alternatively measure your pet’s neck, then add a couple of inches.

        On most dog and cat collars you will see the neck length quoted such as 8"-11".  The diagram above shows you how this measurement is calculated.  If the pet collar length is quoted - this is most likely the full length of the collar from buckle to the opposite end. It is best to go for a collar size where the neck size sits mid-way.  This will allow you the room to alter accordingly.

        Note: for Sighthounds such as the Greyhound and some other long necked breeds, the collar is worn much higher, actually at the top of the neck below the head, but in measuring for coats and similar garments, the neck measurement for these dogs is taken lower than the collar, about midway between collar level and withers.  For dogs with short thick necks, such as Pugs, and dogs with a very full coat in the neck/chest area like Pomeranians, determining the neck measurement can be a bit tricky. For most clothing, and neckwear accessories like bandanas on this type of dog, you may want to use a neck measurement taken a bit lower than collar level (closer to the withers) for a more flattering fit.

        Pet Harness Measuring Guide

        Pet harnesses are measured by chest circumference. This is the widest part of your pet's chest, usually just behind the front legs.

        Some pet harnesses need you to check the neck size. This is the size that will need to be large enough to slip over your pet's head comfortably. Harnesses sit just below the neck on top of the shoulders - so should be slightly larger than the actual neck size. 

        Pet Socks Measuring Guide

        Our pet socks are mainly suitable for tiny to small breeds of pets. It is important to measure your pet's paws accurately, taking into account their paw width and length. Socks that are too big will fall off easily and socks that are too small will not be comfortable for your furry friend.

        Each brand of pet socks may have their own sizes which means a small in one design may be a medium in another so always click on the 'Sizing Guide' or check in the product description found on each product page to double check the measurements of those particular socks. Socks sizes are governed by length and width. Examples of typical sizes are shown in the diagrams below:
