An odd spot on the top abit to the side a few inches below the top of her neck
It sounds like your dog is experiencing a range of skin issues, including scabbing, excessive itching, a bad smell, and flaky skin, particularly on her back. Additionally, she's showing signs of lethargy, loss of appetite, sneezing, and itching, which have been ongoing for about two weeks. These symptoms could be due to several underlying causes, such as allergies (environmental or food-related), bacterial or fungal infections, or even parasites despite the use of topical flea and tick treatments.
Here are some steps you can take at home to help manage her symptoms:
First, consider giving her a gentle bath using a hypoallergenic or medicated shampoo designed for dogs with sensitive skin. This can help soothe her skin and reduce itching. Be sure to rinse thoroughly to avoid any residue that might irritate her skin further.
Next, since food allergies can sometimes cause skin issues, you might want to switch her to a hypoallergenic diet or a limited ingredient diet. It might take some time to see improvements, so be patient and consistent with the new diet.
You can also apply a soothing ointment or cream designed for dogs to the affected areas. Aloe vera gel or coconut oil can provide some relief from itching and irritation.
Ensure her living environment is clean and free from potential allergens. Regularly washing her bedding and vacuuming your home can help reduce dust and other allergens.
To prevent her from scratching and worsening the condition, you might consider using an Elizabethan collar (cone) temporarily.
Given the combination of skin issues and other symptoms like lethargy and loss of appetite, it's important to monitor her closely. If her condition doesn't improve or worsens, it would be best to consult a veterinarian. They can perform tests to identify the exact cause and provide appropriate treatment, such as antibiotics for bacterial infections or specific medications for allergies.
