4-month puppy has red eyes & boogers. Is it an environmental allergy?

Hi , my puppy around 4 months old is getting red eyes repeatedly. I’ve been taking her to work with me and while we were gone from home for longer periods of time I’d notice her eyes were clearing up but when we’d get home she’d start to get the red eyes again. It’s mostly just her one eye. This has been happening for about a week now. She’s also having increased eye boogers throughout the day. I thought it must be an environmental allergy because it kept coming and going but I’m not sure.

Hi, and thanks for your question. This sign could be compatible with an upper respiratory tract inflammation/infection or possibly to a conjunctivitis (inflammatory, allergic, infective). A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
