Christmas Alpaca Dog Pajamas

The 2 Pack Dog Fleece Striped (+ solid) Sweaters are wonderful! My miniature poodle seems to greatly enjoy both sweaters. He is 7.6 lbs and the medium fits him well while being spacious to accommodate his fluffy hair when his hair is long. Fitwarm did an excellent job with the design. I appreciate the sewing because there are no itchy or rough seems throughout. So glad I bought the 2 pack! The colors are lovely ❤️

Cute Floral Dog Sweater

Perfect in every way!!

These turtleneck sweaters are amazing for my pugs! They are soft, warm and cozy. The size medium fits my two smaller 15-16 pound pugs perfectly! They wash and dry wonderfully. The material is soft and they have great stretch to them which means they are easy to put on and they don’t stretch out as your dog wears them. I love the fabric, which is a substantial weight, stretchy, velour, over fleece or knitted sweaters because amazingly the dog hair doesn’t get stuck all over them! I ordered the three pack of pink tones for my new girl and loved them so much that I went back and ordered the three pack of purple and the three pack of green!

2 Pack Fleece Sweater

Light, cool and sun protection

The UV Protection T-Shirts are lightweight and cool for warm weather. Our small rescue girl has several in all the colors Fitwarm offers. She looks adorable in all of them; especially pretty lavender. Even when it is warm, I like her to wear something colorful to be seen easily in our big backyard.
