I have a 70lb doberman (3xl), 92lb shepsky (4xl), 105lb doberman, male tall and thick (4xl) and a Giant Mastiff weighing in at 139lb Rocks his 5xl and looks fly in it! We have soo soooo many spark paws clothes, they are our favorite!!!!!
Fit is borderline small... just depends on the item. I just always try to go up in the winter. The quality is phenomenal. My female dobe likes to rip her brother's jackets right off him, she's a brat!!! It takes her soooooo much longer to tear up his spark paw ...
