Finally, after Three tries from Two different companies we found a Harness that fits our Precious Little Boy (Sir Papi De Mi Corazon) a 3 lb Chihuahua.
The first one (×××s)received from Fida was an Inch too Small around his Chest, even though according to his measurements and the size chart provided by Fida it should have fit. We sent it back, and went a size Larger(××s). It fit Perfectly!
It has a Solid Chest Piece, instead of several Straps %26 Connectors making it Lighter, Softer %26 more Comfortable for him.
Would Definitely Recommend, just be aware of the Size Difference between Actual Measurements %26 Sizing Chart.
