Pet owners should pay close attention to any significant, unusual, or ongoing changes in their pet's normal behavior, appearance, appetite, mobility, or physical condition. Veterinary care may be necessary if your pet experiences a loss of appetite, repeated vomiting, ongoing diarrhea, sudden weight loss, unusual weakness, or difficulty walking.
Excessive scratching, changes in the skin or coat, difficulty urinating, persistent coughing, unusual swelling, visible wounds, signs of pain, or sudden behavioral changes can also indicate an underlying health problem. More serious warning signs include seizures, significant bleeding, severe dehydration, suspected poisoning, breathing difficulty, or loss of consciousness.
Some symptoms may appear minor at first but can worsen if left untreated. Severe, sudden, or rapidly worsening symptoms require prompt veterinary attention to help protect the pet's health and prevent potentially serious complications.
