some boxers have droopy eyes, just how they are. some droop because they are tired. Reese's eyes dont droop, and Savannahs will if she is tired. i have been owned by other boxers though that have had very droopy lower lids. just one of those quirky boxer traits
Abby's get really red when tired, when stressed and after playing hard (long walk, running burns a long time or playing hard with Brady). As for droopiness...the only that our vet mentioned to us was with respect to our cocker, who has droopy (cute!) eyes...the vet jsust mentioned that when eyes are too droopy, they can be subject to more infections. So he just recommended that we keep our eye out for infections and if it became a recurrent problem (so far, so good), there is a surgical procedure they can do to correct the droopiness...but this is only if recurrent infections occur.
gunnar's are red and droopy too. my vet said it's normal, his eyes droop and form little pockets and dirt and gunk collect there, which makes them red, like allergies kinda. i just try to keep them as clean as i can.
Kane had boogies in his eyes when I first got him, but I started washing his face with a clean warm washrag every morning and in no time it vanished. I think it probably has to do with pollens and dust blowing around. But he likes his faced washed either way and it seems to keep the gunk away.
another thing to watch out for is Ectopic something.. Its where they are born with their eyelids being out of kilter or something close.. They get alot of eye boogers because the eyelid is rubbing the eye and irritating it. Vet said it could also cause the animal to go blind.
