Why does my dog keep getting pink eye and spreading it to my puppy?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Cattle Dog | Male | unneutered | 1 year and 5 months old | 45 lbs

Hello, I have a almost 2 year old blue heeler which seems to have "pink eye". This would be his second time getting "pink eye", the first time was in July 25, 2017. I took him to the vet and they prescribed him Vetropolycin. He did not have any scratches in the eye, according to the eye test. The infection went away after 3 days. As of yesterday, he got the infection again and now passed it on to my 7 month old German shepherd puppy. Can you tell me what may be the causes of the eye infection?

Hello, sorry to hear about Blue. Some causes of eye infections can be bacteria (typically gram positive organisms) most commonly. Occasionally, dry eye may cause reddening of the eye without an actual infection. Other causes of a red eye include a superficial ulcer or even uveitis or glaucoma which are both more severe. However, if both of your dogs have it, I would be most suspicious of an infectious process. Most corneal ulcers and pink eyes may resolve on their own, however, some may need a topical antibiotic like the one you were previously prescribed. If Blue's eye is not better by tomorrow, then I would definitely have him evaluated by a veterinarian. Hope this helps and best of luck.
