🚨 Emergency Symptoms

⚡emergency

Seizures

Seizures are a neurological emergency. While brief seizures are not always life-threatening, they require immediate veterinary evaluation to determine the cause and prevent recurrence.

🫃emergency

A bloated, hard abdomen in dogs can indicate GDV (gastric dilatation-volvulus or "bloat"), which is a life-threatening emergency requiring immediate surgery. Large, deep-chested breeds are at highest risk.

⚠️ Urgent Symptoms

🦿urgent

Limping

Limping indicates pain or injury.

😷urgent

Coughing

Persistent coughing can be kennel cough or heart issues.

💧urgent

Excessive Thirst

Drinking significantly more water than usual (polydipsia) can signal kidney disease, diabetes, Cushing's disease, or other metabolic conditions in dogs.

👂urgent

Ear Infection Signs

Ear infections are one of the top reasons for vet visits. Dogs with floppy ears, allergies, or who swim frequently are especially prone.

⚖️urgent

Unexplained Weight Loss

Unintentional weight loss in dogs is always worth investigating. It can indicate parasites, dental pain, organ disease, cancer, or malabsorption issues.

📋 Other Symptoms to Monitor

🤮monitor

Vomiting

Occasional vomiting in dogs is common, but persistent vomiting needs veterinary attention.

💩monitor

🍽️monitor

Not Eating

Loss of appetite can range from picky eating to serious illness.

🐕routine

Excessive Scratching

😮‍💨routine

Bad Breath

While some degree of dog breath is normal, persistently foul breath often indicates dental disease, which affects over 80% of dogs over age 3.

🍑routine

Scooting (Dragging Bottom)

When dogs drag their bottom along the ground, it usually indicates anal gland issues, which are one of the most common reasons for vet visits.

👁️monitor

Eye Discharge

Some eye discharge is normal, but changes in color, amount, or consistency can indicate infection, allergies, or eye injury requiring treatment.

Frequently Asked Questions

How do I know if my dog's symptoms are serious?▼

Emergency signs include difficulty breathing, collapse, seizures, bloated abdomen, inability to urinate, uncontrolled bleeding, or suspected poisoning. Symptoms marked "urgent" warrant a vet visit within 24-48 hours. "Monitor" symptoms can be watched at home for 1-2 days if your dog is otherwise eating, drinking, and behaving normally.

What are the most common reasons dogs visit the vet?▼

The most common reasons include vomiting, diarrhea, skin issues (scratching/itching), ear infections, limping, coughing, and not eating. Many of these resolve on their own, but persistent symptoms lasting more than 48 hours typically need professional evaluation.

Should I give my dog human medication for symptoms?▼

Never give your dog human medication without veterinary guidance. Common OTC medications like ibuprofen and acetaminophen are toxic to dogs. Even "safe" medications like Benadryl require proper dosing from your vet. Always call your veterinarian before administering any medication.

When should I take my dog to the emergency vet vs. waiting?▼

Go to the emergency vet immediately for: difficulty breathing, seizures lasting more than 3 minutes, suspected poisoning, severe trauma, bloated/distended abdomen, inability to stand, or profuse bleeding. For other symptoms, call your regular vet during business hours for guidance.
