Hill’s Science is great for allergies and has been tested with scientific rigor and under the supervision of veterinary nutritionists.
It is made with real chicken listed first on the label, which means that chicken is the main ingredient.
Hill’s Science Diet for sensitive stomachs is rich in antioxidants which aid bowel repair and promote good skin condition.
It is formulated to be easy to digest and gentle on the stomach of dogs with a sensitive constitution.
This formula is considered the best dry dog food for itchy skin because the ingredients are good quality and it doesn’t contain artificial flavors, preservatives, or colors.
However, it is not a true hypoallergenic diet as it contains a range of ingredients, rather than a single protein or carbohydrate source. But if you are looking for an affordable, good quality diet to suit a sensitive stomach then Hill’s Science could be it.

Canidae contains high-quality ingredients with lamb as the main ingredient.
Importantly it is wheat-free and uses healthy options such as sweet potato, chickpeas, and peas as a carbohydrate source.

To promote healthy digestion it contains probiotics and has good levels of omega 3 and omega 6 oils to improve skin health and promote a glossy coat.
Canidae also makes other flavors to the same high standard, including unusual protein sources such as bison, which is a good option if you suspect your dog has food allergies and wish to try feeding a flavor they haven’t eaten before, making it a best dry dog food allergies.

Whilst this food does not meet the strict criteria that would make it appropriate for an exclusion diet to see if your dog has allergies (For this the Purina HA is advisable) it is a good, high standard food that has a restricted range of proteins and non-wheat based carbohydrates.
The main ingredient is venison meal – the keyword here being ‘meal’ as it is the by-products of venison rather than the pure meat.
The carbohydrate is supplied by brown rice and oatmeal, which are both healthy and nutritious.
The Nutro does have limitations but no more so than other competitor diets.

Bottom Line
And finally, when selecting a food for your dog with a sensitive stomach or food allergies look for a food that lists pure meat (rather than meat meal) as number one ingredient and a source of carbohydrates that are not derived from wheat, but from alternative sources such as sweet potato, brown rice, or oatmeal.
This combination of pure meat and a non-wheat carbohydrate is a good starting point for the best dry dog food for dogs with allergies.
