Hello, my dog had 2 molar teeth removed 4 days ago, and from the swelling, the vet said this had caused cherry eye and the third eyelid gland has come out. The vet said that it shouldn't be too long untill the gland will recede back in when the swelling goes down , which it has, but the gland is still out and now it has gotten very red around his whole eye, especially the gland which prior was pink. His eye is also very dry. Please take a look at the attached picture and any advice as to whether i need to seek treatment immediately would be appreciated. Thanks
