Purina Pro Plan Dog Food Review
I’ve been using Purina Pro Plan for months with my dogs. The result? Better energy, better stomach health, and a coat that shines.
Is Purina Pro Plan Dog Food Good?
Yes. Purina Pro Plan dog food is good. It’s one of the few brands I actually trust and use. It gave my dogs steady energy, a shiny coat, and fewer stomach flares.
I first tried Purina Pro Plan Sensitive Skin & Stomach when my dog had soft stools. Within 7–10 days, things were better. Firmer. Less gas. Less itching. I saw the change.
Later, I tested Purina Pro Plan Sport 30/20 during long hiking weeks. That formula has 30% protein and 20% fat. It kept my dog strong and fast. No crashes. No muscle fatigue. That blend is built for active dogs. And it delivers.
The big reason I trust it? Real research and real experts. They have 500+ vets and pet food scientists on the team. That’s rare. And some vet formulas even need a prescription. That level of vet trust matters to me.
What I Like
- It works fast for sensitive stomachs
I saw firmer stools, less gas, and better skin in days. That’s real relief, not hype.- Top-level sports nutrition is real
The Sport 30/20 formula fueled long hikes and high activity. No fatigue. No weight drop. Just steady power.- Many protein choices (my dogs love that)
Chicken, salmon, beef, lamb, turkey, even bison. My picky eater actually ate meals again. No begging needed.- Easy to find in the U.S.
I can buy it at Chewy, Amazon, Petco, PetSmart, and even vet clinics. No waiting. No out-of-stock stress.
What Could Be Better
- Some recipes have corn, wheat, or by-products
Not ideal for dogs with allergies. Some dogs may react poorly.- A few bags smell too strongly
I noticed this myself. Not every bag, but it happens.- It’s not the cheapest
The special formulas cost more. Worth it for results, but still pricey.- Past complaints can worry buyers
There was a March 2023 recall for one prescription diet due to high Vitamin D.
It was limited. It was voluntary. But worth knowing.
Recommendation
Pick Purina Pro Plan dog food if:
- You need tummy support (Sensitive Skin & Stomach is great)
- Your dog is very active (Sport 30/20 shines here)
- You want science-backed recipes
- You value vet and expert input
- You live in the U.S. and want easy store access
Maybe look at other options if:
- Your dog reacts to corn, wheat, or chicken
- You want a grain-free-only diet
- Budget is tight
Kirkland Dog Food Review
I’ve been feeding Kirkland dog food to my dog for over a year. I’ve seen his health, mood, coat, and energy change in real time.
Is Kirkland Dog Food Good?
Yes. Kirkland dog food is good for most dogs. It gives solid nutrition, real meat first, and great value. I’ve fed it to my own dog for over a year. It worked well for us. His coat looked shinier. Energy stayed steady throughout the day. He also maintained a healthy weight.
I tried Kirkland Signature Chicken & Rice and later Nature’s Domain Salmon & Sweet Potato. Both were easy transitions. No weird smell. No sudden stools.
It is not a vet diet brand like Rx formulas. But it meets AAFCO nutrient rules. That matters. It is a mid-tier dog food with high value. And it feels honest for the price.
What I Like
- Quality for the price:
I pay less and still get real meat, whole grains, and solid nutrition. My dog stayed full. No fast hunger like with cheap kibble.- Many protein options:
I can switch between chicken, lamb, beef, or salmon. When my dog seemed bored, salmon saved the day. He cleaned the bowl.- Formulas for life stages:
Puppies, adults, seniors, and weight control — they have a fit for most needs. It feels simple and stress-free to pick.
What Could Be Better
- Store access is limited:
It is mostly at Costco or Costco online. No Costco? It gets tricky.- Some dogs don’t handle certain proteins:
I met dog owners who said chicken or yeast caused itch or upset. Not every dog clicks with the same mix.- A few health complaints online:
I saw reports of tummy issues like loose stool, gas, or itching. Rare, but worth noting. I had no major issues, but I watched the switch closely.
Recommendation
I’d pick Kirkland dog food if you want solid food, low cost, and no fancy extras. It worked great for my dog. No drama. No stress. Just steady results.
Choose this if:
- You want good value
- Your dog has no big food allergies
- You like simple, proven formulas
Maybe skip if:
- Your dog needs a vet Rx diet
- Chicken or yeast causes issues
- You don’t live near Costco
Best picks I’d start with:
- Kirkland Signature Nature’s Domain Salmon Meal & Sweet Potato
- Kirkland Signature Nature’s Domain Beef Meal & Sweet Potato
- Kirkland Signature Chicken & Rice
If you’re in the USA, Costco makes this easy: big bags, clear labels, fair cost. For most homes, it hits the sweet spot between quality and budget.
