Common causes & symptoms to monitor

Common hair loss issues in dogs include:

1. Allergies: Dogs can lose hair due to allergies, resulting in itching and skin irritation.
2. Parasites: Fleas, mites, or ticks can lead to bald patches and intense scratching.
3. Infections: Fungal or bacterial skin infections can cause hair loss and skin discomfort.
4. Hormonal Imbalances: Conditions like hypothyroidism can lead to hair loss and changes in coat texture.

Hair loss can be generalized or localized (e.g. bald patches). Additional symptoms may include redness, inflammation, sores, and excessive licking or scratching. Consulting a veterinarian is crucial for accurate diagnosis and treatment.
