Bringing home a puppy is exciting, but young dogs are vulnerable to several serious diseases that can affect their health quickly. New dog parents should be aware of common illnesses like parvovirus, distemper, rabies, kennel cough, and intestinal parasites. Symptoms such as vomiting, diarrhea, coughing, fever, weakness, or loss of appetite should never be ignored. Vaccinations, regular vet checkups, proper hygiene, and a balanced diet are essential to protect your puppy from these life-threatening conditions. Early detection and preventive care can help ensure your furry friend grows into a healthy, happy companion.
