What could be the causes of skin problems in dogs? Many dogs experience itching, redness, or hair loss. To treat these skin issues effectively, it is essential to understand their origin.
Allergies: a common cause of skin problems
Allergies are one of the most frequent reasons for skin issues in dogs. There are several types of allergies:
- Food allergies (triggered by specific proteins in the diet)
- Environmental allergies (dust mites, pollen, grasses, molds, household dust)
- Contact allergies (reaction to cleaning products, shampoos, or fabrics)
💡 Allergic skin tends to weaken the skin barrier, making infections by bacteria or fungi more likely.
Parasites: fleas, mites, and other causes
Several external parasites can cause significant skin irritation:
- Fleas
- Sarcoptic mange (caused by mites that trigger intense itching)
- Demodectic mange (due to an overgrowth of naturally present skin mites)
When left untreated, these parasites can worsen the symptoms and lead to secondary infections.
Skin infections in dogs
Skin infections, whether bacterial or fungal, can also explain lesions, itching, and hair loss. These infections often occur when the skin barrier becomes damaged, especially due to allergies or repeated scratching.
Hormonal and metabolic disorders
Some hormonal conditions may lead to chronic skin issues:
- Hypothyroidism (underactive thyroid gland)
- Hyperadrenocorticism (Cushing’s disease, excess cortisol production)
These disorders affect the health of the skin and coat, often causing symmetrical hair loss, thin skin, or recurrent infections.
When should you consult your veterinarian?
It’s important to consult your veterinarian if your dog shows:
- Persistent itching
- Redness or unusual hair loss
- Skin lesions, scabs, or crusts
- Greasy, dry, or foul-smelling skin
A thorough veterinary exam will help determine the exact cause of your dog’s skin problems and provide the right treatment.
Conclusion: why does my dog have skin problems?
Skin problems in dogs can result from many causes, including allergies, parasites, infections, or hormonal imbalances. A proper veterinary diagnosis remains essential to relieve your dog’s discomfort and improve their quality of life.
