Plain-English summary
A study found that about 29% of dogs with skin allergies related to food had an allergic reaction to milk proteins. Specifically, many of these dogs reacted to casein, a protein found in milk, which could be a significant cause of their skin problems. This information is important because some vaccines contain casein, and dogs with this allergy might have adverse reactions to those vaccines. If your dog has skin issues and you suspect a food allergy, it might be worth discussing milk allergies with your veterinarian.

Abstract
We investigated the IgE reactivity to crude and purified milk antigens in the sera of 112 dogs with cutaneous adverse food reactions (CAFRs). Of the 112 dogs, 33 (29%) had specific IgE for crude milk antigens. In the dogs with milk-specific IgE, IgE reactivity to casein, bovine serum albumin (BSA), α-lactalbumin, β-lactoglobulin, and bovine IgG were 81%, 85%, 39%, 27%, and 35%, respectively. Casein and BSA may be important allergens in dogs with CAFRs. Some canine vaccines contain casein hydrolysate as a stabilizer and the pooled serum with anti-casein IgE showed IgE reactivity to the vaccines containing it. Information about IgE reactivity to casein in dogs with CAFRs could be useful for predicting adverse reactions to the vaccines including casein hydrolysate.
