My doctor says for human eyes, you should use ice for 24 to 48 hours around that area. After that you can use heat, but if heat makes it worse, then go back to using ice. Should be the same for dogs, but again, be careful and take her in when you can...
Hopefully someone else can chime in? We'll all be thinking of you little Hailey, Mommy will take care of you!
