Smartbites Immune Support Crunchy & Soft Chicken Flavor Dog Treats
Verified May 25, 2026
These are low-calorie, crunchy-and-soft chicken-flavor treats for adult dogs, designed to be used as a complement to a regular diet. They provide a moderate protein and fat level for a treat, and are fortified with vitamin E and other nutrients to help support immune function. The recipe is grain-inclusive and uses chicken meal and animal fat as key animal-derived ingredients.
Nutritionally, these are well-formulated functional treats for adult dogs, with reasonable calorie content per piece and added vitamin E to support immune health. Chicken meal as the first ingredient provides animal protein, and the overall protein and fat levels are appropriate for a small snack. They’re best used in moderation alongside a complete and balanced dog food, especially for dogs that tolerate chicken and grains well.

At a Glance
KibbleLab Review
Strengths
- Chicken meal as the first ingredient offers a named, concentrated animal protein source for a treat.
- Relatively high protein (29%) and moderate fat (15%) for this type of product, which is good for a snack item.
- Fortified with vitamin E and other vitamins and minerals to support overall nutrition and immune function.
- Very low calorie per treat (about 2 calories), which helps with weight control when used as directed.
Considerations
- Contains chicken and wheat, which can be problem ingredients for dogs with known allergies or sensitivities to these foods.
- Includes animal fat and animal plasma; while nutritionally useful, dogs with unknown food sensitivities may need a supervised trial to ensure good tolerance.
- These treats are not a complete diet, so total daily treat intake should stay within the recommended number and main meals should be adjusted to avoid excess calories.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
02
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
03
Whole Wheat
Whole wheat is used primarily as a carbohydrate and fiber source in pet foods, offering energy, some plant-based protein, B vitamins and minerals and more fiber and nutrients than refined wheat. It can aid digestion and satiety—particularly in dogs—but is not essential for obligate carnivores like cats and may cause allergic or gluten-sensitive reactions in some pets, so it should be avoided in animals with known wheat intolerance, certain metabolic conditions (e.g., obesity, diabetes) or specific dietary restrictions.
04
Animal Fat
Animal fat is used in pet foods as a concentrated energy source and palatability enhancer, and can provide fat-soluble vitamin absorption and essential fatty acids (including arachidonic and linoleic acids, depending on the source) that support skin, coat and overall cellular function—particularly important for obligate carnivores like cats. Because it is calorie-dense and prone to oxidation, fats are typically rendered and stabilized; owners should be aware that high-fat diets can contribute to obesity and may trigger pancreatitis in susceptible dogs, so quality, source, and total dietary fat should be considered.
05
Mixed Tocopherol
Mixed tocopherols are a blend of natural vitamin E compounds (alpha, beta, gamma and delta tocopherols) used in pet foods primarily as a natural antioxidant and preservative to protect fats and fat‑soluble nutrients and extend shelf life. They also supply dietary vitamin E—an essential antioxidant for immune function, skin and coat health and cellular integrity in dogs and cats—and are generally safe at typical use levels, though they are not a substitute for a complete vitamin formulation and may be less effective in animals with fat‑absorption disorders.
