One of the major reasons for skin problems in summer is fleas, especially if
there is an infestation. Other common causes are Atopic dermatitis, mange,
Demodectic mange, bacterial infection, hypothyroidism, Cushing’s syndrome.
Sometimes the clinical exam isn’t enough to reach a diagnosis and a para-clinic
exam (culture of skin scraping, or microscopic exam) may be required.
advice is to administer a good product for fleas and ticks protection like
Frontline Plus, K9Advantix or K9AdvantixII every month and administer treatment
for internal parasites every 3 months. You can also start consider administering
a diet especially formulated for sensitive skin as this can be helpful.
