Why is my dog losing hair around one eye? Allergies or other?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing her allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. This could also be due to something like mites and that can be easily determined with an exam and basic cytology which your veterinarian can perform. There are medications such as Apoquel or prednisone which may help with the itch. 

There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. 

Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). 

If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests.

 Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

Hair loss in that area is generally due to allergies, mites or less likely and autoimmune disease. You can try giving Shadow an over the counter antihistamine to see if it helps. Wipe his eyes out daily to keep them clean. If he is rubbing the eyes, put an elizabethan collar on him to protect them. If you are not seeing any improvement, or if he is getting worse, I would recommend a vet visit. Taking care of things early is much better. I hope this helps Shadow.

Small amounts of hair loss at the corners of the eyes is not likely to be associated with an actual eye problem fortunately. In the absence of any itchiness, this is not something I would be terribly concerned about at this time. Keep an eye on the issue for spreading of hair loss or adversely effected eyes. If you want immediate answers to the problem, the only way to do this is with dermatologic diagnostics include skin scrapings, cytology, cultures, and/or biopsies of the areas of loss. Hope this helps.

Oh dear, poor Gidget! Some of the most common causes of hair loss and black discoloration of the skin around the eyes include allergies, ringworm, and mange. Skin discoloration can occur as a result of chronic irritation and inflammation of the skin. If Gidget is scratching at her face or rubbing it on the ground, I recommend putting an e-collar (cone) on her to prevent further hair loss and also to prevent injury to her eyes that could occur from her scratching/rubbing. Otherwise, the best thing that you can do is to take her to her vet for an exam. The vet may need to perform a skin scrape (to check for the presence of the mites that cause mange) or a fungal culture (to check for ringworm). Based upon their exam and test findings, they will be able to prescribe the best medication for Gidget, whether it is an antifungal, anti-parasitic, antibiotic, or anti-inflammatory medication. I hope that all goes well for Gidget!

Without a photo it would be hard to say. Irritation from rubbing, minor allergies, etc can all be potential causes. If the area becomes bothersome, doesn't heal, changes in size or shape, becomes red, or oozes debris, then it should be checked out by your vet.

It looks like Noel could have a skin or eyelid infection secondary to something like allergies, ringworm, or mange (a mite infection). Some autoimmune skin diseases can cause similar signs. I would recommend seeing your vet - they might want to take a sample to examine for mites or infection, then may recommend some oral or topical treatments.

I recommend getting this checked by your vet. It could be a small injury, it could be a form of mange, it could be an infection, there's no way to know for sure without an exam. Your vet will do an exam, probably a skin scrape of the affected area and based on these results, will be better able to tell you what is going on and what the best treatment will be.
