Puppies instinctively conceal illness—so it falls to attentive caregivers to spot subtle clues that something isn’t right. This guide details early warning signs—ranging from eye/nose issues to behavior and elimination changes—explains why each matters, and outlines when to call your vet or use **Ask A Vet**. Plus, discover how **Woopf** and **Purrz** can support your puppy during recovery.

1. 👁 Eye & Nose Discharge or Irritation

Clear tear staining is often normal, but thick, yellow/green discharge, squinting, pawing, cloudiness or redness—particularly around the eyes—suggests infection, foreign bodies, or distemper :contentReference[oaicite:3]{index=3}.

• Symptoms: watery, crusty, smelly eyes; pawing at face.
• Concern: conjunctivitis, infection, kennel cough, distemper.
• Action: call vet or via **Ask A Vet** if discharge is persistent or colored.

2. 🤒 Fever or Abnormal Temperature

Normal puppy temperature is 99–102.5 °F by 4 weeks age :contentReference[oaicite:4]{index=4}. A resting temperature >103 °F or <99 °F—combined with lethargy, appetite loss, or shivering—could indicate serious illness.

• Check rectally using a pet thermometer.
• Elevated temperature may signal infection; low suggests shock or hypothermia.
• Action: seek vet care immediately.

3. 🍽 Appetite & Thirst Changes

• Refusal to eat >24 hrs or lack of interest in favorite foods.
• Excessive thirst or begging behavior.
• Action: record amounts, consult **Ask A Vet** and bring puppy in if persistent.

4. 💤 Lethargy or Behavior Changes

Puppies are playful by nature—sluggishness, isolation, whimpering, or irritability may indicate pain, infection, or congenital issues :contentReference[oaicite:6]{index=6}.

• Signs: sleeping more, withdrawing, unwilling to play.
• Concern: pain, anemia, heart disease, early parvo/distemper.
• Action: monitor closely, call vet if no improvement in 24 hrs.

5. 🤢 Vomiting & Diarrhea

While puppies commonly vomit/drop stools due to teething or diet changes, persistent vomiting/diarrhea—especially with blood, mucus, or fever—indicates infection (parvo, distemper), parasites, or blockages :contentReference[oaicite:7]{index=7}.

• When mild: feed small bland meals (rice & boiled chicken).
• When serious: blood in stool, multiple vomits per day, dehydration.
• Action: urgent vet visit—especially if fever, pale gums, or weakness.

6. 🚾 Changes in Bathroom Habits

Increased or decreased urination, accidents, straining, or blood in urine can indicate urinary tract infection, kidney issues, diabetes, or congenital malformations :contentReference[oaicite:8]{index=8}.

• Monitor output and ability to urinate/poop normally.

7. 🐕 Respiratory Signs—Coughing, Sneezing, Breathing Problems

• If cough lasts >5 days or respiratory distress occurs, seek vet help.
• Calm environment, hydration, and use **Purrz** diffuser to support breathing.

8. 🪶 Weight Loss or Failure to Grow

Regular weigh-ins are vital—unexpected weight loss, failure to gain, or plateau without reason may indicate illness, parasites, or congenital disease :contentReference[oaicite:10]{index=10}.

• Use weekly weigh-ins or body condition scoring.
• Action: record and share trends with your vet or via **Ask A Vet**.

9. 🐛 Skin, Coat, and Ear Issues

• Action: early treatment can prevent infestations or chronic dermatitis.

10. 👣 Neurological Signs & Abnormalities

• Monitor onset and pattern—note time, duration.
