I LIKE BIG MUTTS dog sweater - size large

NWT. Blue knit doggie sweater with I Like Big Mutts design. New, never been worn. Size is large but I think my pup parents would agree this runs a bit small. Neck circumference approx 16”. Sweater end to end is 18”. must go over doggie head and then slip legs through the leg holes (see pics). Has slit for back clip harness.
