Short answer: panting after heat or exercise is a normal way to cool down, but if panting continues even at rest, or comes with coughing or a change in gum color, it's worth considering as a possible sign of heart disease.
How is this different from normal panting?
Panting from heat, exercise, or excitement typically settles down after a while. If panting continues even while your dog is calmly resting, that could be a sign outside the normal range.
What are the 4 warning signs of possible heart disease?
① Persistent rapid breathing even at rest ② A dry cough, especially one that worsens at night or while lying down ③ Gums turning pale or bluish ④ Getting tired easily with only minimal exercise. If these four appear together, it's worth paying closer attention.
Which breeds should be extra cautious?
Some small breeds have a higher tendency to develop heart valve disease as they age, so if you have a senior small dog, it's worth watching their breathing pattern more closely.
Is there a way to check at home?
Counting your dog's breaths for one minute while they're calmly resting is a useful baseline. If it's noticeably faster than usual, jot it down — it'll be useful info to share with your vet.
What signs mean I should go to the vet?
If resting respiratory rate is clearly faster than usual, coughing keeps recurring, or you notice a change in gum color, it's safest not to wait and get a heart checkup.
