Your puppy threw up, or skipped breakfast, or suddenly started limping, but somehow still has enough energy to zoom around the house. Now comes the question every puppy parent eventually asks: Do I call the vet, or do I wait and see?

With puppies, it isn't always easy to tell. Some symptoms can be monitored at home, while others warrant a call to your veterinarian or a trip to the emergency room, and because your puppy can't exactly tell you how they're feeling, knowing what to look for can make those decisions a little easier. 

So, we asked Dr. Doug from Juno Veterinary to help us play a round of “Call the Vet or Chill?” He walked us through common puppy scenarios, from vomiting and soft stool to coughing, limping and changes in energy, and explained when puppy parents can monitor, when it's time to pick up the phone and which signs shouldn't wait. The biggest takeaway? Look at the whole puppy, not just one symptom. Their appetite, energy, behaviour and interest in the things they normally love can tell you a lot about how they're feeling. 

When should you take your puppy to the vet?

There are generally three ways to think about changes in your puppy's health:

• Monitor at home: Your puppy has a mild or isolated symptom but otherwise seems like themselves.
• Call your vet: Something is persisting, happening repeatedly or being accompanied by other changes in your puppy's behaviour.
• Seek emergency care: Your puppy is showing signs that could indicate a serious or rapidly developing health problem.

One of the most important things to consider is not just the individual symptom, but how your puppy is acting overall. Are they eating? Drinking? Playing? Interested in treats? Responding to you normally? A single soft stool in an otherwise energetic puppy is very different from diarrhea in a puppy who suddenly seems exhausted and doesn't want to eat.

Here's how Dr. Doug breaks down some of the scenarios puppy parents commonly encounter.

Call the Vet or Chill? 9 Common Puppy Health Scenarios

1. My puppy vomited once but is still eating and playing

Verdict: Monitor for now.

One isolated episode of vomiting doesn't necessarily mean something is seriously wrong, particularly if your puppy immediately returns to their normal behaviour. Keep an eye on them and watch for additional symptoms or repeated vomiting. If your puppy vomits three to five times in one day, Dr. Doug recommends contacting your veterinarian.

2. My puppy hasn't eaten all day

Verdict: Monitor closely, then call your vet.

Puppies can occasionally have changes in appetite, but prolonged refusal to eat deserves attention. According to Dr. Doug, if your puppy hasn't eaten for more than 24 hours, contact your veterinarian.

There is another important distinction to make: is your puppy simply uninterested in their regular meal, or have they lost interest in everything? If your puppy refuses their food but happily accepts a favourite treat, that's different from a puppy who doesn't want food, treats, toys or other things they normally get excited about. 

3. My puppy has no energy and doesn't want food, treats or toys

Verdict: Seek emergency veterinary care.

A puppy who suddenly has very little energy and has lost interest in food, treats and play is showing more than an isolated symptom. Dr. Doug considers this combination of symptoms a reason to seek emergency veterinary care.

Pay attention to changes from your puppy's normal. Puppies sleep a lot, but when they're awake, they should generally still respond to the things they usually enjoy.

4. My puppy has diarrhea and seems really tired

Verdict: Call your vet right away.

One unusual bowel movement is very different from gastrointestinal symptoms paired with a noticeable change in behaviour. If your puppy has diarrhea and appears unusually tired or lethargic, Dr. Doug recommends calling your veterinarian and having them examined.

5. My puppy had one soft stool but otherwise seems normal

Verdict: Monitor for now.

One soft stool doesn't necessarily warrant a trip to the vet. If your puppy is otherwise eating, drinking, playing and behaving normally, you can generally monitor them and see what their next bowel movement looks like. If the diarrhea continues, becomes severe or is accompanied by other symptoms, contact your veterinarian.

6. My puppy is limping but still wants to play

Verdict: Call your vet and discuss an appointment.

A puppy who is limping but still energetic and interested in playing may not need an immediate trip to the emergency room, but the limp is still worth discussing with your veterinarian. Dr. Doug suggests calling your vet and potentially scheduling an appointment for the following day. If your puppy is unable to bear weight, appears to be in significant pain or the limping follows a major fall or injury, the situation may require more urgent care.

7. My puppy is coughing

Verdict: Monitor and get a video.

Dr. Doug calls this one a “semi-chill.” If your puppy coughs but otherwise seems well, record a video if you can. Coughing can be difficult to reproduce once you're actually in the exam room, so having a recording gives your veterinarian more information to work with. Monitor your puppy and contact your veterinarian with the video if the coughing continues or you're concerned. If your puppy is struggling to breathe rather than simply coughing, however, that's different. Difficulty breathing should be treated as an emergency.

8. My puppy's gums look white or very pale

Verdict: Go to the ER.

Healthy gum colour can provide useful information about your puppy's circulation and overall health. If your puppy's gums appear white or very pale, Dr. Doug recommends going directly to an emergency veterinarian. Pale or blue gums are also recognized as potential emergency warning signs alongside symptoms such as difficulty breathing and collapse.

9. There's blood in my puppy's stool

Verdict: It depends on how much.

Seeing blood in your puppy's stool can understandably be alarming. According to Dr. Doug, a small amount of streaking blood may be something you can monitor while arranging an appointment with your veterinarian rather than heading immediately to the ER. But if your puppy's stool appears to consist primarily or entirely of blood, seek emergency veterinary care. As with other symptoms, pay attention to the bigger picture. Blood accompanied by repeated diarrhea, vomiting, weakness or lethargy should be taken seriously.

Important: These are general guidelines, not a diagnosis. Your puppy's age, medical history, vaccination status and other symptoms can change how urgently they need care. If you're unsure, contact your veterinarian.

When in Doubt, Call Your Vet

Perhaps the most important advice from Dr. Doug is also the simplest: If you're worried about your puppy, it's ok to call. You don't have to diagnose the problem yourself before picking up the phone. Knowing your puppy's normal behaviour can help you notice when something has changed. Pay attention to their appetite, energy, stool, movement and interest in the things they usually love. Sometimes the answer will be, “Keep an eye on them.” Sometimes it'll be, “Let's get them in tomorrow.” And sometimes it'll be, “Head to the ER.” The important part is knowing that you don't have to make that call alone.
