Hello, I've got a 5 month old Lab who has purple/dark skin on the knuckles of each paw, they seem to be itchy and he constantly wants to lick them. I've put a cone on him and changed his diet to a single protein, and it has been 2 weeks and he has not improved yet. His paws have a weird smell to them and his eye lids tend to be reddish at times. Lastly he has developed strange looking black spots on his stomach near his genitals

Poor Roco. It sounds like he most likely has allergies. It may be to the protein in the food, or environmental allergens, or a combination. It sounds like you are on the right track to try to change the protein, but it may be that he needs a prescription diet from your veterinarian. It may also be that he has a yeast infection on top of allergies. The black spots most likely are areas of hyperpigmentation from the allergies. I would recommend you speak w your veterinarian about allergies, an allergy diet, and doing some skin testing. Good luck
