I understand you're concerned about your dog's swollen ear. It's important to remember that I'm an AI and cannot provide medical advice.

Here's what I can tell you:

* Swollen ears can have many causes. An insect bite is one possibility, but it could also be an allergic reaction, an ear infection, or something else entirely.

* It's crucial to take your dog to the vet. They can examine the ear, determine the cause of the swelling, and provide appropriate treatment.

Here are some things you can do while you wait for your appointment:

* Keep your dog's ear clean and dry. You can use a soft cloth to gently wipe the area.

* Avoid putting any medications or creams on the ear without consulting your vet.

* Monitor your dog for any other signs of illness. These could include fever, lethargy, loss of appetite, or changes in behavior.

Please do not delay in seeking veterinary care. Your dog's health is important, and prompt treatment can prevent complications.
