Will the seams irritate my dog’s skin or damage his/her coat?

No. The Arctic Fleece Bodysuit (like all our garments) is made by a world leading sportswear manufacturer here in the United States. The seams are sewn using a special technique and machine that creates flat seams. This reduces any friction or irritation from the seam, and actually creates a stronger more durable seam. Thus we can guarantee our garments seams for life.
