How to Measure Your Dog 

Waist - This is measurement A 

Using your tape measure, measure around the waist of the dog where you want the nappy to sit. If your dog is a boy and you are measuring for a belly band, be sure to include his penis in the measurement.  

When taking this measurement leave room to move, you do not want the waist of your pets nappy too tight. The wasit on all Dundies products is adjustable, so you can always tighten them. 

Length ( Belly to Back) - This is measurement B 

This measurement is only needed for Snappies and All in Ones. As per the diagram, you are measuring from where you want the nappy to sit on your pets back, running it all the way along your dogs bottom, past their tail, through their hind legs and onto their belly. This is the overall length of the nappy. 

This measurement is important so that your dogs Dundies sit at the right height on their back, and don't sit too short like hipster jeans. 

Common Dog Breeds & Their Sizes

Dogs bottoms are not easy to guess the size of. A bulldog, like sophie in the video, wears a size large. This is because they have very wide bums, where as a greyhound that is a much larger dog, also wears a large because they have a more thin longer bum. This breed guide in conjunction with measuring your dog can help you determine the ideal size for your pet. Please keep in mind that these recommendations are based off standard size for that breed, so if you dog is larger than normal, is overweight or is underweight, it is always best to measure.
