My puppy's eye is droopy, losing hair, and irritated. What's wrong?

It looks like an infection around the eyelid. This can happen if the eye has been excessively moist lately. The other common cause of this hair loss around the eye is a mite known as Demodex. This is normally seen in puppies. Sport looks like he's a senior, so it's less likely, but still possible. The cause of the swelling can usually be identified by a veterinarian. They can look for the mite and treat for infection. The vet will also be able to give medication that will take down the swelling, which is much needed now. For now, it's best if you can flush the area with saline. You can find this at the local pharmacy or supermarket in the eye care section. Flush for 15 seconds twice a day. This will give some relief and help to treat/prevent infection. I recommend taking Sport to the vet within the next few days to keep this from getting worse.

Have your dog seen by a vet. Your dog could have an eye infection or may have injury his eye. Any eye problem needs to be checked out by a vet promptly as leaving it untreated can lead to vision loss.

An allergy would likely cause more general symptoms instead of affecting just one area. Discuss any additional medications with your vet before given any. An e-collar (cone) should be used to prevent pawing. If current therapy is ineffective, consider a recheck with your veterinarian or veterinary ophthalmologist.

It appears he may have an entropion. This is where the eyelids roll inward so the hair and lashes can scratch the eye and cause irritation. This maybe secondary to confirmation or secondary from swelling. Your vet can check for an ulcer and hopefully prescribe anti inflammatory meds if there is not one. From there, they will check for dry eye and discuss surgery to fix the entropion to provide permanent relief

I would get this checked by your vet as soon as possible. It could be a number of things, from fungal or bacterial infections, to mange. Identifying it quickly can save a lot of time and trouble as some of these conditions are a challenge to clear up. Your vet will do an exam, pluck some hairs and possibly do a skin scrape, which involves scraping a dulled scalpel blade on the skin to remove hair and a little skin to examine under the microscope. Based on these tests, your vet will be better able to tell you what is going on with your puppy's skin and how to treat it.

Squinting the eye abnormally could be caused by pain which could be caused by a variety of conditions, including allergies, bacterial or viral infection, corneal abrasion or ulcer, or something stuck under the eyelids. The discharge you described could occur with any of these conditions. I would recommend that you have Bella examined by a vet since eyes can go downhill very quickly. The vet will do a thorough exam and may need to do one or two tests to determine what is going on so they can select an appropriate treatment.

It's hard to see from the picture, but it may be something that C is getting into causing the irritation. Allergies to food or the environment can sometimes cause irritation and bumps on the body, sometimes around the eyes. If the bumps come and go, making a note of any potential triggers such as a certain type of treat given before they appear, or playing at a particular park/location happens prior may help you pinpoint if an allergy is the case. Parasites, infections from bacteria, fungus and yeast can also cause irritation and redness, and a skin scraping from your vet may help narrow that down as a possible cause. Even if the bumps aren't actively there, having the area examined by your vet may turn up some answers behind why it is happening.
