Purina ONE SmartBlend Review: Pros, Cons and Verdict

Our verdict
Purina ONE SmartBlend Chicken & Rice is a solid, widely available adult kibble for a healthy Border Collie with no special dietary needs. It puts real chicken first, adds prebiotic fiber and natural glucosamine sources, and is easy to find almost anywhere. Skip it if your dog has a known chicken sensitivity or you want a grain-free or limited-ingredient food. The 8 lb bag is fine for a trial but runs out fast for an active collie.
- Best for: Healthy adult collies on a sensible budget
- Not for: Dogs with chicken sensitivities or puppies
Purina ONE isn’t a trendy food, and that’s partly why so many collie owners end up feeding it. It’s in nearly every supermarket, the formula doesn’t change every six months, and most dogs eat it without fuss.
That counts for more than people think with this breed. Border Collies can be funny about food: some are greedy, some go off their bowl when they’re stressed or bored, and plenty have touchy stomachs. A predictable, easy-to-buy kibble that agrees with your dog is worth a lot. Here’s what the SmartBlend Chicken & Rice formula offers and where it falls short.
What it is
SmartBlend is Purina ONE’s name for its blend of ingredients in the red-bag line. This is the Chicken & Rice formula, an adult dry food with real chicken listed as the first ingredient. Purina describes it as high protein, with a microbiome balance that includes prebiotic fiber to support gut health.
The listing also mentions omega-6 fatty acids, vitamins and minerals for skin and coat, four antioxidant sources for immune support, and natural sources of glucosamine for joints. It’s labeled as 100 percent complete and balanced nutrition for adult dogs. The bag reviewed here is 8 lb.
It sits in the middle of the market. It’s a step up from basic grocery kibble in how the ingredients are presented, but it isn’t trying to compete with fresh, raw or limited-ingredient diets. Think of it as a dependable everyday option rather than a specialist food.

Pros, cons and verdict
Chicken first, without the boutique price tag
Real chicken leads the ingredient list, and the formula is described as high protein to support muscle and energy. For a collie who runs, herds or does agility, that’s the baseline you want. It isn’t a premium raw-style diet, but it doesn’t claim to be.
The gut-health angle
Purina leans on the microbiome message here, with prebiotic fiber included to support digestion. Collies are known for sensitive stomachs, and a steady, consistent food is often the biggest help. If your dog has ongoing loose stools or vomiting, that’s a vet conversation rather than a food swap.
Coat support for a double coat
Omega-6 fatty acids, vitamins and minerals are there to support skin and coat. A Border Collie’s dense double coat shows diet quickly; a dull, dry coat or heavy dandruff is often the first sign something’s off. This formula covers the basics, though dogs with skin issues may do better on a fish-based option.
The 8 lb bag runs out fast
An active 40 lb collie eats a fair amount, and an 8 lb bag won’t last long. It’s a good size to see whether your dog likes the food and tolerates it, but once you’re settled, a larger bag is more practical. Check the live listing for the sizes on offer.
Chicken and grains won't suit every dog
This recipe contains chicken and rice. That’s fine for most collies, but not for one with a diagnosed chicken allergy. If your vet has flagged a protein sensitivity, look at the lamb or salmon versions instead.
Kibble that works as a training reward
This is an underrated point for collie owners. A plain, dry kibble is easy to carry in a treat pouch and doesn’t leave greasy crumbs in your pocket. Many collies will work happily for their regular food, especially if part of breakfast is earned during a ten-minute training session.
That matters for a breed that learns fast and gets bored faster. Feeding part of the ration through short drills, scatter feeding in the garden, or a puzzle toy turns a meal into a job, and a collie with a job is usually a calmer collie.
Pros
- Real chicken is the first ingredient
- Prebiotic fiber and natural glucosamine sources
- Widely available and consistent
- Complete and balanced for adults
Cons
- 8 lb bag is small for active collies
- Not suitable for chicken-sensitive dogs
- Adult formula only, not for puppies
Tips for Border Collie owners
- Switch foods gradually over about a week, mixing more of the new food in each day. Collie stomachs often react to sudden changes.
- Use the feeding guide on the bag as a starting point, then adjust for your dog’s activity and body condition. A working collie and a sofa collie can need very different amounts.
- Pull training treats from the daily ration. Kibble works well as a reward for simple drills, which keeps your dog from putting on weight.
- Feed some meals from a puzzle toy or snuffle mat. Collies need mental work, and making them hunt for kibble helps burn off that busy brain.
- Check with your vet before changing food for a dog with a medical condition, a senior dog, or one with an ongoing stomach or skin problem.

Purina ONE Plus Skin & Coat Sensitive Stomach. Real salmon is the first ingredient, with vitamin E and omega-6 for skin and coat. Worth a look for collies with dry skin or a sensitive tummy, and it comes in a much bigger 31.1 lb bag. Check price
Frequently asked questions
Is Purina ONE SmartBlend good for Border Collies?
For a healthy adult collie with no food sensitivities, it's a reasonable everyday kibble. It has chicken first and is complete and balanced for adults. Dogs with allergies or medical needs should follow their vet's advice.
Can I feed it to a Border Collie puppy?
This formula is labeled for adult dogs. Puppies need a puppy-formulated food until your vet says it's time to switch, which for many collies is around their first birthday.
How much should I feed my collie?
Start with the feeding chart on the bag for your dog's weight, then adjust. If you can't feel the ribs easily, cut back a little; if your dog looks lean and hungry after lots of exercise, add a bit.
Is Purina ONE grain free?
No. This recipe includes rice. Most dogs do well with grains, and grain-free diets are a topic to discuss with your vet before switching.
What if my collie gets an upset stomach after switching?
Slow the transition down and go back to a mix with more of the old food. If the upset lasts more than a day or two, or there's vomiting or blood, call your vet.
Bottom line
Purina ONE SmartBlend Chicken & Rice is an honest, everyday food that suits a lot of healthy adult Border Collies. It does the basics well, it’s easy to buy, and it’s consistent from bag to bag.
Start with the 8 lb bag to see how your dog takes to it, switch slowly, and move to the lamb or salmon versions if chicken doesn’t agree with your collie. For more options, see our guide to the best food for Border Collies.
