Let’s be real for a second: Rottweilers are basically big teddy bears with jaws of steel. They’ll guard your house, cuddle you on the couch, and—yes—stare into your soul every time you open the fridge. And we’ve all been there, thinking, “A little bite won’t hurt, right?”
Spoiler alert: sometimes it will.
I’ve spent years working with Rottweilers—training them, feeding them, and occasionally watching their humans panic over a grape incident. So, to save you from those “OMG, what did he just eat?!” moments, here’s a friendly list of 10 foods you should never let your Rottie near.
You’re welcome. 😉
1. Chocolate—No, It’s Not a “Little Treat” 😅

I know. Chocolate is the love of your life. But for your Rottie, it’s a serious no-no.
Here’s why it’s dangerous:
- Contains theobromine and caffeine—toxic to dogs.
- Symptoms include vomiting, diarrhea, increased heart rate, seizures, and even death.
Worse offenders:
- Dark chocolate
- Baking chocolate
FYI: Even a tiny piece of dark chocolate can mess with your dog’s heart rate. Stick to dog-safe treats unless you’re trying to make your vet rich.
2. Grapes & Raisins—Healthy for You, Deadly for Them

This one still shocks people. Grapes seem so… innocent. But they can cause acute kidney failure in dogs. 😱
Even ONE grape can lead to:
- Vomiting
- Lethargy
- Loss of appetite
- And yes, total kidney shutdown
There’s no known “safe amount,” so just treat grapes and raisins like they’re radioactive raisins and keep them off limits.
3. Xylitol—The Silent Killer in Sugar-Free Stuff
Got sugar-free gum, candy, or peanut butter? Better read the label.
Xylitol (sounds like a sci-fi villain, right?) causes a sudden insulin release, leading to:
- Dangerously low blood sugar
- Seizures
- Liver failure
Symptoms can start within 30 minutes. So yeah—if you suspect your Rottie got into your sugar-free stash, call the vet immediately. Don’t wait. Don’t Google. Just go.
4. Fat Trimmings & Cooked Bones – A Recipe for Disaster

I know it’s tempting to toss them scraps like a medieval king, but don’t.
Fat trimmings:
Greasy scraps might seem harmless, but they can kick off pancreatitis—a nasty, painful condition that often lands pups in the ER.
Cooked bones:
They don’t crunch, they shatter. Splinters can choke your dog or slice up their insides. That’s not a tummy ache—it’s surgery waiting to happen. $$$ 🙄
Pro tip: Want to spoil them? Stick to vet-approved chews or dog-friendly treats. If you’re considering raw bones, know they come with their own risks (bacteria, broken teeth), so only try them under supervision and after a chat with your vet.
5. Onions and Garlic – Flavorful for Us, Fatal for Dogs
Raw, cooked, powdered—doesn’t matter. Onion and garlic can wreck your dog’s red blood cells, leading to anemia.
Symptoms to watch for:
- Weakness
- Pale gums
- Rapid breathing
Even small amounts over time can build up to dangerous levels. So no, your Rottie doesn’t need a bite of your onion ring.
6. Tomatoes – Especially the Green Ones
Ripe tomatoes? Not the worst. But unripe ones—and the leaves or stems—contain solanine, which is toxic to dogs.
Bad reactions include:
- GI upset
- Lethargy
- Confusion
- Abnormal heart rate (yikes)
Bottom line? Unless you’re growing tomatoes in your backyard and your Rottie’s a curious snacker (which… they are), this one’s easy to avoid.
7. Raw Potatoes – Not Just a Weird Crunchy Snack
Like green tomatoes, raw potatoes contain solanine too. That means:
- Vomiting
- Diarrhea
- Lethargy
Plus, they’re not exactly a gourmet dog treat, are they? Cooked plain potatoes are fine occasionally, but raw ones? Hard pass.
8. Wild Mushrooms – Nature’s Roulette Wheel
Some mushrooms are totally safe. Others? Yeah, they can kill your dog in hours. Problem is—you (and I) probably can’t tell the difference.
Toxic mushrooms may cause:
- Vomiting
- Abdominal pain
- Seizures
- Liver failure
- Death (yep, that escalated fast)
Golden rule: If you’re hiking and your Rottie tries to eat a wild mushroom, stop them like they’re about to chew on your iPhone.
9. Macadamia Nuts – Fancy, But Freaky
These bougie little nuts can seriously mess with your dog’s nervous system.
Even a few can cause:
- Weakness (especially in the back legs)
- Vomiting
- Tremors
- Fever
We don’t even know why they’re toxic to dogs—just that they are. So let’s keep your Rottie away from trail mix, yeah?
10. Nutmeg – No Pumpkin Spice for Your Pup
Nutmeg contains myristicin, which sounds like something in a science experiment and, well… it kind of is.
Symptoms include:
- Disorientation
- Hallucinations (yep)
- Increased heart rate
- Seizures
So next time you’re baking holiday cookies and your dog gives you the look, toss them a dog biscuit instead. They won’t know the difference. 😉
Wait, So What Can Rottweilers Eat?

Let’s not be all doom and gloom here. Your Rottie deserves good food—just the right kind.
Try these instead:
- Cooked lean meats – chicken, turkey, beef
- Veggies – carrots, green beans, sweet potatoes
- Fruits – blueberries, apple slices (no seeds!), bananas
- Eggs – cooked, please (no Rocky-style yolks)
Oh, and peanut butter? That’s a yes if it’s xylitol-free. Always check the label first. Like, every single time.
Bonus FAQ – Because I Know You’re Wondering…
Can Rottweilers eat cheese?
Sure! In moderation. Some are lactose intolerant, though, so start small unless you want to find out the hard way.
Are raw diets safe for Rottweilers?
Controversial topic alert 🚨 IMO, it’s risky unless you really know what you’re doing. Raw meat = potential for bacteria = no thanks.
What about fish?
Yes—but cook it and debone it first. Salmon and whitefish are great for shiny coats and healthy hearts.
Final Thoughts: Feed with Love (And Smarts)
You love your Rottie. I know you do—I mean, have you seen that face?? But love sometimes means saying, “No, buddy, you can’t have my garlic bread.”
Remember: just because it’s safe for you doesn’t mean it’s safe for them.
So, stick to the good stuff, avoid the scary stuff, and keep your furball happy, healthy, and snacking ’safely.

Now go give your good boy (or girl) a treat they can eat—and tell them I said hi. 🙂
