I am so pleased with these shirts! They are amazing quality and so cute! My cat seems to be comfortable in them as well. This brand is my go to for pet clothes. I definitely recommend both this brand and this shirt!Challenging to find shirts for my 4.5 pound guy, but this fits perfectly and no pee through!Don’t be like me. I should have listened to the reviews and sized up. Whiskey is a puppy, and he wears an XS, but this shirt runs small. It fits more like a crop top—minimal stretch. The colors are vibrant and soft/breathable enough for dogs. @whiskey.partipoodle is 4.5 pounds.Shirts should be purchased in a larger size than suggested. A bit to snug for suggested size.Bought an XL for my dog and it doesn't even cover his back.My dog loved his little shirt, well I loved it for him. It is very long which fits him well because he has a long torso. It isn't very soft but fits very well.It is very difficult to find clothes that fit my dog around the neck in length and around the arms and belly. These shirts fit perfectly and are very soft.
