The Adnikia turtleneck dog sweater is knit from plush, high-stretch DeRong fleece that traps body heat while allowing unrestricted movement. Its calming swaddle design features wide chest panels that cross over, distributing gentle, swaddling pressure to lower heart rate during storms or fireworks. Four-season versatility makes it a Uv-blocking cover in summer and a windbreaker in fall. Easy on and off with an adjustable elastic toggle.
