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.
