Do I need to use pads with your diapers & belly bands?

Not necessarily, depends on the situation. The diapers themselves are very absorbent, but you may want to use the pads for heavier urination times such as overnight and travel. Many customers also use them when the dog is in heat. They are completely washable. The pads are also great at helping to keep your dog dry as they wick the moisture away from their body.
