Before You Buy
Key Buying Factors
01
Limited Ingredients
Fewer ingredients reduce the chance of triggering allergies. Look for diets with a single protein source and limited carbohydrate sources.
02
Novel Protein
Proteins like lamb, salmon, or venison are less common in commercial diets, making them less likely to cause allergic reactions.
03
Omega Fatty Acids
Omega-3 and omega-6 fatty acids support skin barrier function and reduce inflammation. Sources include fish oil, flaxseed, and sunflower oil.
04
Grain vs. Grain-Free
Some dogs with allergies benefit from grain-free diets, but grains are rarely the culprit. Choose based on your dog's specific sensitivities.
05
Additives and Preservatives
Artificial colors, flavors, and preservatives can exacerbate allergies. Opt for natural preservatives like mixed tocopherols.
06
AAFCO Statement
Ensure the food meets AAFCO nutritional requirements for your dog's life stage. This guarantees complete and balanced nutrition.
Living With It
Care, Cost and Maintenance
Transition Slowly
Over 7-10 days, gradually mix increasing amounts of new food with old to avoid digestive upset.
Monitor for Reactions
Watch for changes in itching, redness, ear infections, or gastrointestinal issues. Note any improvements or setbacks.
Consistency is Key
Stick with the chosen diet for at least 8 weeks to assess effectiveness. Avoid frequent food changes.
Pro tip
When switching to a limited ingredient diet, we recommend keeping a food diary to track your dog's symptoms and identify any lingering triggers.
Frequently asked questions
How long does it take for a new diet to improve skin allergies?
Most dogs show improvement within 4-8 weeks, but it can take up to 12 weeks for full effect.
Can I mix Nutro Limited Ingredient Diet with other foods?
It's best to stick with one diet to identify triggers. Mixing can introduce new allergens.
Are grain-free diets better for skin allergies?
Not necessarily. Grain allergies are less common than protein allergies. Grain-inclusive diets can be equally effective.
What should I look for in the ingredient list?
Look for a single animal protein source, limited carbohydrate sources, and no artificial additives.
Can these foods be fed to puppies?
Only if labeled for all life stages or growth. Most are for adult maintenance.
