A Small Breeds: If you have a small breed puppy, such as a Chihuahua or a Yorkshire Terrier, smaller pads will suffice. Look for pads that are around 17" x 24".
Medium Breeds: For medium-sized breeds like Beagles or Cocker Spaniels, you’ll need larger pads. A size of 22" x 23" is usually appropriate.
Large Breeds: Large breeds, such as Labrador Retrievers or German Shepherds, will require the largest pads available, typically around 28" x 34" or larger.
