Eye injury after dog play

Our 2 year old Cardigan Welsh Corgi spent the weekend at a friends while we were on vacation. Their pet (large golden retriever) and ours played often. At one point there was a fight between them over a bone and our dog was injured on the eye.

Our friends told us there was a little blood from the edge (enough to drip on carpet). A day later when we picked him up there was only redness/swelling and some discharge that discolors the fur below the inner corner of eye. He seemed a little tired, but that is common after a weekend of fun.

He is a little hesitant if you get to close to the eyes but otherwise it does not seem to bother him. My guess is there is a little soreness. We did notice a little additional blinking of the eye which seems to be some irritation.

He does not seem to be bothered by light and is now running around like normal. The wet fur was dried off earlier today and within a couple of hours it is wet again so the clear discharge is continuing. It is hard to tell how red (if any) the eyelid rims are since his other eye is rimmed in black and we can’t compare. The white of his inured eye is red (bloodshot). He had no problems with me taking the photos and handling the area. Just a brief hesitation as I got close to it.

I saw some information on eye rinse/cleansing to do, but did not want to aggravate it unnecessarily. Do you think we should take him to the vet, do any home remedies or just a little TLC until it improves?

Thanks!
