The last few days you’ve noticed your dog looking at you a little funny, it was almost like a cute winking in one eye or both. Today though, you are sure of it – your dog is genuinely squinting and it is in both eyes. “My dog won’t open his eyes,” you think. So what should you do?
Anytime your dog is having a problem with his eyes, you should take it seriously and consult your veterinarian. There are many potential eye problems in dogs that may or may not be serious. Your vet can help determine the underlying cause, whether it be benign in nature or something severe, and set your dog on the right treatment program.
In majority of cases when pet owners running into the vet’s office saying my dog won’t open his eyes, the reason is dog eye pain. There’s something that causes your pooch pain whenever his eyes are open, thus he chooses to keep them closed to avoid eye pain.
When a dog is suffering from an eye pain, their reactions are to squint and keep their eyes closed. Sometimes your dog may show signs of behavioral distress. Your dog could hide it by sleeping more, or can show decreased appetite, aggression, and hiding behaviors. There are several things you need to consider if your dog won’t open his eyes, so here’s everything you must know.
My Dog Won’t Open His Eyes. What Should I Do?
Canine Eye Pain
Canine eye pain or discomfort can occur from either external or internal irritation of the eye (Dr. Mcnabb, 2015). There can be other signs of eye pain in dogs, including pawing at the eyes, or an avoidance of hard foods and a refusal to fully open his mouth, too.
Dogs can’t tell you what they are feeling, so it may not always be easy to know that your dog’s discomfort is due to eye pain. There are many different causes that could be behind your dog’s eye pain including eye infections, bacteria or injury. The first thing most owners do is try a few basic at home remedies like saline to flush the eyes; after that, if your dog won’t open his eyes still, then you have to seek the help of a professional.
In most cases when you find yourself saying my dog won’t open his eyes, the likely cause is that your pooch is suffering from eye pain that needs to be dealt with. Your dog’s eyes reaction to pain is due to a high concentration of pain fibers or nerves within the cornea and conjunctiva. The highest distribution of these nerve fibers is located near the surface.
A corneal ulcer or scratch can be extremely painful and cause a reflexive spasm of the iris inside the dog’s eye. The severe pain that these types of dog eye nerve reactions can cause your dog will result in your dog squinting or holding his eyes shut completely as a way to cope or try to deal with the pain.
The important thing is that once you realize that flushing with saline or dog eye drops is not a solution, that there is no debris in your pet’s eye to cause the discomfort, you need to seek medical attention for your dog immediately to determine what could be any one of a number of causes of eye pain. Below is what you should consider.
Common Causes of Eye Pain
There are many different causes of eye pain that your veterinarian will go over with you when you arrive. Your vet will use special equipment to look into your dog’s eyes to see things that are not visible with the naked eye.
Your veterinarian is looking for signs that point to common causes of eye pain. Some of these causes of eye pain in dogs that veterinarians find more frequently, according to Merck Vet Manual, are:
- Debris or other foreign material on the surface of the eye.
- Inflammation of the iris or anterior uveitis may cause dog eye pain. Your vet will have to determine the direct cause of the uveitis in order to treat.
- Dog glaucoma, which causes an elevated pressure on the inside of the eye, can feel like a pain sensation to a dog. Their instinct can be to hold their eyes closed.
- Trauma, or some type of injury to the eye tissue or the eyelids, may be causing pain.
- Internal eye socket (orbital) infections are extremely painful and will often cause signs of mouth related issues, such as refusal to open his jaw.
- Dry eye, or KCS (keratoconjunctivitus), can cause dogs to have a painful gritty, dry sensation on the surface of the eye. This can lead to keeping the eyes closed.
Your veterinarian will go over the common causes of eye pain while examining your dog. Generally, it will be one of these conditions that is causing your dog’s eye pain and your vet can start a treatment plan right away. Your vet can use a special ophthalmic medication, atropine, to immediately reduce the symptoms of pain for your dog.
Furthermore, in some occasions your dog may be keeping his eyes shut because of the dog eye care products you’ve used to deal with this like dog eye boogers (tear stains). Some of these can be overdone, and others are not always completely safe, even if they’re effective. Angel Eyes for Dogs, for example, is a controversial product.
Symptoms of Dog Eye Pain and Issues
When your dog is having eye pain, he’s likely to demonstrate this in a number of ways. If you’re saying my dog won’t open his eyes, then it’s the first sign of something being wrong. But other signs can be physical, while others are behavioral. Some dog eye pain symptoms may be obvious to you and others you may not even notice.
While there are several dog eye care products you can try to flush out your pet’s eyes to make sure there’s no debris, if your dog still won’t open his eyes after that, a vet visit is a must.
Your veterinarian will discuss the number of symptoms that you should be watching for as you start treatment for your dog’s eyes. These symptoms are also the most common signs of dog eye pain in which you should seek veterinarian assistance right away:
- Squinting or closed eyes
- Excessive tearing
- Mucus or any pus-like discharge from the eyes
- Bloodshot or red eyes
- Any type of cloudiness, bluish haze or filmy covering of the eye
- Dilated, constricted or uneven pupil sizes
- Photophobia, which is fear of bright lights
- Excessive rubbing of eyes
- Cherry eye, or red covering of the eye
- Pain when opening the jaw
Any time that your dog is showing these types of dog eye pain symptoms, it is time to call the veterinarian. It is important because even if you do not understand your dog’s fear of bright lights or hiding behavior, know that not all eye diseases cause direct eye pain sensations.
Your dog may be having other eye difficulties that it is having trouble expressing, such as a type of dog eye allergy. The only way to know is through a complete and thorough examination at the vet’s office.
Eyes are a very sensitive issue, so this must not be delayed. If you find yourself looking up information online on my dog won’t open his eyes, and you’ve already tried washing them, then it’s time to call your vet. Ignoring it may not only impair your dog’s sight, but its ability to communicate.
Complete Examination of Dog Eye Pain
When your dog gets to the veterinarian or specialist, the first thing is to go over your dog’s complete medical history and do a thorough physical examination. Your vet will then begin a complete ophthalmic examination.
Often the dog’s eye exam can only be done after the vet uses a topical pain reliever to stop the squinting, and even after that, most dogs have so much anxiety about the pain and the procedures that many doctors opt to sedate the dog in order to be able to do a more thorough exam of the eye.
Your vet will do a number of tests including a Schirmer test, a fluorescein stain of the cornea, and a tonometry. Using magnification, an examination of the eyelids and the surface of the dog’s eyes are completed.
From there your vet can do additional eye examinations as needed such as an ocular ultrasound. Complete blood counts are also taken to see if there are any other underlying conditions. Because eye pain in dogs can be a symptom of a severe health problem, all possible conditions need to be ruled out through a thorough examination and diagnosis.
Corneal Ulcers in Dogs
Corneal ulcers are one of the most common causes of eye pain in dogs (NHAH, 2014). A corneal ulcer can be a very serious condition and is often caused by trauma. They are also very difficult to treat, and some veterinary sources say that it may even be impossible.
Dogs rubbing their eyes on carpet or getting a cat scratch can cause an ulcer. Veterinarians use the fluorescein stain to see the layers of the epithelium to see if there is an abrasion or ulcer in the dog’s eye, and how deep it has formed.
Corneal ulcers in dogs are a very serious condition that requires veterinary attention right away. It’s painful for the dog, and your vet can help get treatment started immediately.
Glaucoma in Dogs
Glaucoma is a common condition that results in eye pain in dogs. This condition causes pressure to be placed on the dog’s eye, causing inner eye fluid drainage blockages.
Glaucoma can become a chronic condition. It can cause eye pain and if left untreated will eventually lead to blindness. However, regardless of treatment, over 40% of all dogs who get glaucoma will go blind within a year, even if they get treatment (Slatter, D. 2001).
When you run into the vet’s office saying my dog won’t open his eyes, your veterinarian will prescribe a treatment plan for your pooch to follow based upon the diagnosis that he receives after examination. It is important that you follow the plan accordingly. It could include things like steroid eye drops, antibiotics, or even surgery.
You need to be sure to follow through with your veterinarian’s orders. Your dog’s eyes will last its lifetime and is its way of getting through life, protecting itself and you, and expressing its emotions and feelings.
Your best friend made a commitment to you, no strings attached, now it’s up to you to follow through and help your dog get through this medical emergency.
