Diaper Liners & Booster Pads
Booster pads help increase absorbency for times when changing your pet's diaper or wrap might be more difficult (e.g. at nighttime or while your pet is sleeping). Use with disposable or reusable doggie diapers or belly bands.
On the other hand, diaper liners will absorb the pee from your pet and prevent leaks, so using liners with washable diapers and male wraps allows you to reuse the diaper and requires less frequent washing.
