Hair loss and scabbing on your Chihuahua's ears can be attributed to several potential causes. Considering the age of your pet, one possibility is an endocrine disorder such as hypothyroidism, which can lead to skin changes and hair loss. Another common cause could be a skin infection, either bacterial or fungal, which often results in scabbing and hair loss. Additionally, parasitic infestations like mites (for example, scabies or demodex) can lead to similar symptoms.

Given that your dog is on flea and tick prevention collars, it's less likely that fleas are the cause, but it's important to ensure that the collar is effective and changed according to the recommended schedule. Also, allergies, either environmental or food-related, can cause skin irritation and hair loss.

To help your pet, ensure that the environment is clean and free from potential allergens that could exacerbate skin issues. Regularly wash your dog's bedding and any areas where he spends a lot of time. It's also beneficial to maintain a balanced diet that supports skin health; some diets are specifically formulated for skin and coat health.

For immediate relief, you can use a gentle, hypoallergenic shampoo to soothe the skin. Be careful when cleaning the ears not to cause any further irritation. If the scabs are severe, a topical ointment prescribed by a veterinarian may be necessary to promote healing and prevent infection.

It's crucial to monitor for signs of infection such as increased redness, swelling, or discharge from the affected areas. If your dog seems to be in pain, is excessively scratching or shaking his head, or if there's a foul odor coming from the ears, these could be signs of a more serious condition that needs immediate veterinary attention.

In the current condition, if you notice any of the following symptoms, it would be wise to seek immediate veterinary care: difficulty breathing, significant changes in behavior or appetite, vomiting, diarrhea, or signs of pain such as whining or reluctance to move. These symptoms could indicate a more serious underlying health issue, especially in a senior dog with a history of heart conditions.

Remember, maintaining regular veterinary check-ups is important for senior pets to monitor their overall health and manage any chronic conditions effectively.
