Diagnosing Common Illnesses

Respiratory infections in dogs manifest with symptoms such as coughing, sneezing, nasal discharge, and breathing difficulties.

Treatment typically involves seeking veterinary advice for accurate diagnosis and potential antibiotic or medication administration.

Gastrointestinal problems, characterized by vomiting, diarrhea, appetite loss, and abdominal discomfort, necessitate maintaining hydration and temporarily withholding food, followed by a gradual introduction of bland meals like boiled chicken and rice; persistent symptoms should prompt a veterinary consultation.

Skin ailments, evidenced by itching, redness, hair loss, and skin lesions, benefit from regular grooming, hypoallergenic shampoo use, and veterinarian-prescribed medications for effective management.
