Bug bites can get swollen, especially if Yuki is having an allergic reaction. You can contact your vet for the correct dosage of a medication such as benadryl to see if that will help. If the swelling continues or worsens, or affects her head, face, or neck, it is best to bring her in ASAP for immediate allergy shots and some steroids to help the swelling go down. Blisters can sometimes appear "bubble like" and may be red, swollen and balloon and can be due to injuries, burns, friction and more. Keeping Yuki from messing with it is best to prevent infection as it heals.
