Homemade Dog Food for Itchy Skin: Read This Before You Start

Homemade dog food for itchy skin can sound like the kindest option. But a UC Davis study found that of 200 online and book recipes, 95% lacked at least one essential nutrient. Before you cook, talk to your vet about whether food is even part of the problem.

Why is homemade dog food for itchy skin risky?

Itchy skin has many causes. Food is only one of them, and many dogs with a food allergy also have an environmental or flea allergy. So changing the food on a hunch can leave you with a dog who is still itchy and a diet that is missing something.

The UC Davis study looked at 200 online and book recipes. Only 4 were adequate, and those were written by board-certified veterinary nutritionists. That is why we do not give recipes and why we do not suggest you build one from the internet.

How do vets check for food allergy?

The reliable way is a strict elimination diet trial. Your vet chooses the diet and the length. Veterinary guidelines describe 8 to 12 weeks.

Option your vet may choose	What it is
Novel protein diet	A protein your dog has not eaten before
Hydrolyzed prescription diet	A prescription diet type used in food trials
Home-cooked recipe from a nutritionist	Written by a veterinary nutritionist, not found online

Blood, hair and saliva tests are not reliable for food allergy. Hair and saliva tests showed poor accuracy and cannot be recommended.

Why not a pet-store “limited ingredient” food?

Over-the-counter limited-ingredient foods can carry traces of other proteins. That can spoil a trial. Treats, chews, dental sticks, pill pockets, toothpaste, flavored medicines and supplements can do the same.

What should you do before changing your dog’s food?

1. Book a vet visit. Say you are wondering about food, and bring your notes.
2. Write “Everything My Dog Eats.” Include the main food, treats, chews, toothpaste, flavored medicines and table scraps. Your vet can then avoid proteins your dog has already had.
3. Keep scoring the itch. A daily 0 to 10 score and a note about anything new give your vet a baseline.
4. Change nothing until your vet says so. That includes treats, chews and toppings.
5. Check fleas too. A flea comb and a white towel take 5 minutes. Ask your vet about flea control for every pet.

What should you ask your vet?

• Is a food trial right for my dog?
• Which diet, how long, and which treats are allowed?
• Should flavored medicines or flea products be switched to unflavored versions?
• What do I do if my dog slips and eats something off the plan?
• What itch score drop would you count as success, and when is the recheck?

What if you have already started cooking?

You are not alone, and many loving owners have tried it. Do not feel bad. Write down what your dog has been eating, take the list to your vet and ask what to do next. Do not stop or change anything drastically without advice, especially for puppies, seniors or dogs with other health conditions.
