Why Does My Puppies Breath Smell Like Metal? Quick Guide for New Owners
Okay, so the other day, I was snuggling with my new puppy, Gus, and I got a big whiff of his breath. Instead of that sweet puppy breath everyone talks about, it smelled... metallic. Like, seriously, like I was sniffing a handful of pennies. It totally freaked me out!

My first thought, naturally, was, "Oh my god, is he okay?!" I immediately went into full-on panic mode.
My Investigation Begins...
I started by, you know, inspecting his mouth. I gently pried his little jaws open (he wasn't thrilled, let me tell you) and looked around. I didn't see anything obvious – no bleeding gums, no weird sores, nothing stuck in his teeth. Everything looked pretty normal, just... tiny and puppy-like.
Then, I started doing what any modern pet parent would do: I hit the internet. I typed in "puppy breath smells like metal" and, well, a whole bunch of stuff came up. Some of it was reassuring, some of it was terrifying. Teething, apparently, can sometimes cause a metallic smell. Okay, that made sense, Gus is definitely teething – he chews on EVERYTHING.
But then I saw stuff about kidney problems and other serious illnesses. My heart started racing again. I was picturing all sorts of worst-case scenarios.
Calling the Vet
After about an hour of spiraling down the internet rabbit hole, I decided I needed a professional opinion. I called my vet and explained the situation. The receptionist was super calm (thank goodness) and said it could be teething, but it's always best to bring a puppy in for a check-up, especially a new one.
So, I booked an appointment for the next day. I spent the rest of the day obsessively sniffing Gus's breath (he probably thought I was crazy) and trying not to panic. I gave a treat which is good for breath.
The Vet Visit
The vet was awesome. She examined Gus thoroughly, checked his gums, looked at his teeth, and listened to his heart and lungs. She asked me a bunch of questions about his diet, his energy levels, and his, um, bathroom habits.
After the examination, she smiled and said, "He looks great! It's most likely just the teething. His gums are a little inflamed, which is perfectly normal when they're getting new teeth. That can sometimes cause a metallic smell."

I felt such a wave of relief! She recommended some puppy-safe chew toys to help with the teething and told me to keep an eye on him. If the smell got worse, or if he showed any other symptoms, I should bring him back in.
I should observe any changes about:
- Vomiting
- Diarrhea
- Lethargy
Lesson Learned
So, the moral of the story? Don't always trust the internet! It's a great resource, but it can also send you into a panic. When in doubt, call your vet. And, apparently, metallic puppy breath isn't always a sign of impending doom. Sometimes, it's just... teething. Gus is happily gnawing on a rubber bone as I type this, and his breath, while not exactly minty fresh, is definitely less metallic.
