Add a fish oil for the most EPA + DHA

Skin trials used 22 to 85 mg of EPA + DHA per kg a day, which is 500 mg to 1,930 mg for a 50 lb dog, and Deley Naturals Fish Oil gives that in ⅓ to 1⅓ tsp a day for $0.09 to $0.34 a day. Give it two months.11 Our skin and coat guide compares fish oils this way.

What the research says

Colostrum is the first milk from cows; in Purina's dog study it raised gut antibodies.12 In a 2025 review of 5 small trials, probiotics lowered itch and skin scores in every trial.13 Dogs in the fish oil skin trials improved on 22 to 85 mg of EPA + DHA per kg a day.7, 8 If your dog is very itchy, your vet can check for fleas, infection and food allergy and prescribe faster relief.11
