Science Plan Dog Food Review: Real Customer Experiences & Expert Opinions
Okay, let's talk about this Science Plan dog food. I found myself looking for a new chow for my buddy, Buster. He wasn't exactly unwell on his old stuff, but maybe a bit sluggish? And his coat wasn't looking its best. You know how it is, you start noticing little things.

So, I was at the vet's for his check-up, just chatting, and the vet mentioned Science Plan. Wasn't pushy about it, just threw it out there as an option lots of people liked. I'd seen the bags around, of course, they're everywhere. Felt a bit like, "Okay, maybe it's time to try the 'science' stuff," even though I'm usually a bit skeptical of fancy names.
Making the Switch
Decided to give it a go. Picked up a bag of the adult formula, I think it was chicken flavor. First thing I did when I got home was open the bag and take a sniff. Smelled like, well, dog food. Nothing weird or chemical-like, which was a good start. The kibble size looked decent for Buster, not too big or tiny.
Now, I didn't just dump the new stuff in his bowl. Learned that lesson the hard way years ago with another dog! Did the slow switch thing over about a week, maybe a bit longer:
- Days 1-2: Mostly old food, just a little sprinkle of the Science Plan mixed in.
- Days 3-4: Maybe like, three-quarters old food, one-quarter new stuff.
- Days 5-6: Went about half and half.
- Day 7 onwards: Mostly Science Plan with just a bit of the old, then finally just the new food.
I watched him pretty closely during this whole process. Gotta keep an eye on their appetite and, you know, their output. Didn't want any nasty surprises on the carpet.
What I Saw
First impressions: Buster ate it right away. No sniffing and walking off, which he sometimes does if he's suspicious. So, that was a plus. He seemed to like the taste okay from the get-go.
Digestion: This was the big one I was watching. Thankfully, no upset stomach. His poops actually firmed up a bit, which was honestly an improvement. Consistency is key, right? Seemed like he was digesting it well.
After a few weeks: This is where I started noticing more subtle stuff. His energy levels seemed to pick up a bit. Not like bouncing-off-the-walls crazy, but more enthusiastic for walks, more playful in the evenings. Could be coincidence, maybe the weather got nicer, who knows? But it lined up with the food change.
And his coat! This was probably the most obvious change. After about a month, maybe six weeks, his fur definitely looked shinier and felt softer. Less flaky skin too. That made me feel pretty good about the switch.

So, yeah, that was my experience. I went into it just needing a change, heard about Science Plan, gave it a proper try by switching slowly, and watched what happened. For Buster, it seemed to work out pretty well. Coat's better, energy's good, digestion is solid. It's a bit pricier than the old stuff I was buying, gotta admit, but seeing him doing well makes it feel worth it for now. We've stuck with it since.
