How to tell if your dog has fever | Easy guide

Lee este artículo en español

Wondering if your dog has a fever? If they’re feeling off, a little down, and their nose is warmer than usual, it might be time to check for a fever. Recognizing doggy fevers can be tricky, but we’ve got your back with all the signs to look out for and what to do if your furry friend is running hot.

What exactly is a fever in dogs, and when should you worry?

Just like us, dogs can develop a fever when their body is fighting off infections. The challenge is that dogs can’t tell us when they’re feeling crummy, so we have to watch for the signs.

What’s a normal temperature for dogs?

Humans have a normal body temperature of around 98.6°F (37°C), but dogs run a little hotter—think between 101°F and 102.5°F (38°C – 39.2°C). If your dog’s temp is over 103°F (39.5°C), they’ve got a fever. Anything above 106°F (41°C)? Drop everything and get them to the vet ASAP—that’s serious stuff.

How can you tell if your dog has a fever?

The most common signs include:

• Warm, dry nose (but we’ll bust this myth in a bit).
• Lethargy: Is your dog glued to the couch? More so than usual?
• No appetite: If they’re turning down treats, something’s definitely up.
• Diarrhea and vomiting: Gross, we know, but worth mentioning.
• Glassy eyes and shivering: These aren’t normal “I’m cold” shivers—this is a sign they’re feeling feverish.

And if your dog starts channeling their inner soap opera star, complete with dramatic sighs and pitiful looks, it’s time to take action.

How to tell if your dog has a fever without a thermometer

Let’s be real: not everyone has a dog thermometer handy at all times (though you might want to add one to your pet care kit!). But there are still a few tricks you can use to see if your pup’s running a fever.

Physical signs you should look for

• Warm, dry nose: Yeah, we’ve all heard this one, but guess what? It’s not always accurate. Your dog’s nose can feel warm for all sorts of reasons, like the weather or how long they’ve been napping.
• Hot ears: Gently feel their ears—if they’re warmer than usual, that’s a clue.
• Warm belly and inner thighs: These areas tend to hold heat, so check them to gauge your dog’s temp.
• Lethargy: If your dog is acting super lazy or sluggish, it could be a sign.

No thermometer? No problem.

If you’re thermometer-less, you can still use your hands to check for unusual warmth. Feel their ears, armpits, or the inside of their thighs—if they feel hotter than normal, your pup might be fighting off a fever.

How to check your dog’s temperature with a thermometer

If you’re the type to always be prepared (or you’ve learned from experience), having a thermometer on hand is the best way to get an accurate reading.

Step-by-step guide to using a digital thermometer

1. Get the right kind of thermometer: Rectal thermometers are the most accurate for dogs. Yep, it’s not fun, but it’s the best way.
2. Lube it up: A little petroleum jelly makes things more comfortable.
3. Gently insert the thermometer: Insert it about an inch into their rectum. Take it slow—they won’t love it, but it’s necessary.
4. Wait for the beep: Most digital thermometers will beep when they’ve got the reading.

When should you call the vet?

If your dog’s temp is over 103°F (39.5°C), call your vet. And if it’s over 106°F (41°C), it’s an emergency. Get them to the vet fast—this could be a sign of a serious infection or illness.

What’s the deal with warm noses in dogs?

Let’s settle this once and for all. The whole “warm nose = fever” thing? Not always true.

Warm nose myths

Sure, a warm nose might be a clue that something’s up, but it’s not a guaranteed sign of fever. Your dog’s nose temperature can fluctuate depending on a ton of factors—like how long they’ve been asleep or the weather. So if they’ve got a warm nose, don’t panic right away.

What are the real signs of a fever?

Focus on their overall behavior. Are they lazier than usual, refusing food, or just acting weird? These are more reliable signs than just a warm nose.

What can you give your dog for a fever?

Here’s where things get serious: Never give your dog human medicine without talking to a vet first.

Safe medications and what to avoid

You might be tempted to give your dog Tylenol or ibuprofen, but here’s the deal: both are toxic to dogs. Only a vet can prescribe the right meds to treat your dog’s fever.

Home remedies and basic care

While waiting for the vet, here’s how you can help your dog feel better:

• Keep them hydrated: Fever can lead to dehydration, so make sure they have plenty of water.
• Cool compresses: Place a cool, damp cloth on their belly or paws to help lower their body temperature naturally.
• Rest: Make sure they’re resting in a cool, comfortable spot.

How to tell if your dog is sick besides fever

Fever can be a sign of several health issues, but there are other symptoms to watch out for that might indicate illness.

Other signs your dog might be sick

• Diarrhea and vomiting: If it’s happening a lot, it could be something serious.
• Coughing or nasal discharge: Yep, dogs can catch colds too.
• Changes in behavior: If they’re acting off—whether it’s excessive panting, whining, or just not being their usual self—there’s something going on.

When to take your dog to the vet for a fever

If your dog’s fever lasts more than 24 hours, or if they start showing serious symptoms like vomiting, diarrhea, or trouble breathing, it’s time to see the vet.

When fever might signal something serious

A fever can be a symptom of anything from a mild infection to something more serious like distemper. If your dog’s fever doesn’t go down or they start showing other signs of distress, don’t hesitate to get professional help.

Preparing for the vet visit

Before heading to the vet, jot down their symptoms, when they started, and any recent changes in behavior. This info can help the vet make a quick and accurate diagnosis.

Conclusion

If your dog has a fever, the key is to stay calm and act quickly. Keep an eye on their symptoms, check their temperature if possible, and make sure they’re comfortable and hydrated. And if their fever persists or worsens, don’t hesitate to contact your vet.
