The Health Red Flags All Pet Owners Need to Know

Here are the warning signs every pet owner should know and never ignore.

Sudden bloating or a swollen tummy

A pet with a tight, swollen abdomen should always be seen urgently, especially dogs. It might look like they have simply eaten too much, but it can sometimes signal something far more serious, like gastric dilatation and volvulus (GDV), where the stomach fills with gas and twists. It is painful, fast-moving, and can become life-threatening very quickly. Watch for restlessness, repeated retching without bringing anything up, drooling, or obvious discomfort.

Open-mouth breathing in cats

Unlike dogs, cats do not normally pant. So if your cat is suddenly breathing with their mouth open, take it seriously. It can be linked to stress, pain, or breathing difficulties and should always be treated as urgent, particularly if it comes on suddenly or is accompanied by weakness or collapse.

Struggling to urinate or not going at all

Frequent trips to the litter tray or garden with little to show for it is a red flag. Straining, crying out, or passing only small drops of urine needs prompt attention. In male cats especially, a blockage can turn into a full emergency very quickly.

Early signs of heatstroke

Heatstroke does not always start with collapse. Early warning signs include heavy panting, drooling, restlessness, vomiting, wobbly movement, or bright red gums. If your pet seems unsettled or unable to get comfortable in the heat, do not wait to see if it passes.

Sudden lethargy or not quite themselves behaviour

It is tempting to put a subdued day down to tiredness. But if your pet suddenly becomes withdrawn, weak, or uninterested in things they would normally love, pay attention, particularly if other symptoms are present. Sudden lethargy can be an early sign that something more serious is going on.

Repeated vomiting or diarrhoea

One isolated episode is not always cause for alarm. But repeated vomiting or diarrhoea is different, especially if there is blood, signs of pain, weakness, or your pet cannot keep water down. Get them seen as soon as possible.

The bottom line

Pets can go downhill quickly. What seems like a small change can sometimes be the first sign of something much more serious and acting early can make all the difference.
