Reasons Why Dogs` Eyes Become Swollen

It can occur secondary to an irritant like soap or smoke or an invading foreign matter like dust, hair, and grass. Viruses like distemper, herpes, hepatitis, and canine influenza also could cause eye infections. Funguses and parasites have also been known to result in swollen eyes.

Conjunctivitis is an uncomfortable condition that may cause your dog to paw at their eye, blink or squint. You may also notice clear or green discharge from the eye or that the white of the eyes, eyelids or area surrounding your dogs eye are red and swollen.
A sticky, tenacious eye discharge could point to canine dry eye, a failure to make enough tears. Symptoms can also include mucus and inflammation. Dry eye may be the result of distemper, injury, a knock in the head near a tear-producing gland, or the dog`s immune system attacking the tear gland tissue.
Dogs have a third eyelid, or nictitating membrane, in the inner corner of the eye, which is also covered by conjunctiva. In healthy dogs, the conjunctiva of the eyelids is not readily visible and has a pale pink color. When conjunctivitis occurs, the conjunctival membranes become red and swollen.
The best treatment for a dog`s swollen eye is bringing him to a vet, who can administer treatment based on the cause of the swelling. “Most eye issues can be treated with medicated eye drops,” Moucha said. “Some infections need oral medications as well. Sometimes surgery may be necessary.”
A dog`s swollen eye is not something to take lightly, as most eye infections will not go away without treatment. As soon as you notice your dog`s eye is swollen, you should bring them to the vet to get treated.
Apply ice or a cold pack wrapped in a clean, wet washcloth to the eye for 15 to 20 minutes at a time to decrease eyelid swelling and pain. You can safely give your child an allergy medicine or antihistamine by mouth. This will help to decrease eyelid swelling and itching. Benadryl every 6 hours or so is best.
Unfortunately, you would be mistaken to think that the same eye drops you use are suitable for dogs. You should not use human eye drops on dogs. If your dog is experiencing eye irritation, contact your vet and take them in to get an eye examination and possibly eye drops that are safe for dogs.
Dogs can cry in one of two ways: vocally, in a way that tugs at our heartstrings, and with tears. When it comes to those sad-sounding noises, your pooch is most likely trying to express excitement, frustration, anxiety or pain.
The most common causes of new eyelid swelling include allergies, pink eye, and styes, but skin infections, thyroid disease, and herpes are other possible causes.
Your dog`s eyelid may also be torn or bruised due to trauma, like a fight. Begin by placing an ice compress to minimize swelling. Arrange to take the dog to your vet afterward to have the eye checked and prevent an infection from developing.
Any breed of dog may develop viral conjunctivitis if they encounter viruses that cause inflammation in the eye membranes. These viruses are usually quite contagious and can take 3 to 4 weeks to fully resolve.
One popular method is using a warm, damp cloth to gently clean and soothe the eye area. Another option is using a saline solution to flush out any irritants.
An unspayed female dog`s vulva will become swollen as a part of her normal heat cycle, but it should return to its “normal” size after the heat is done (anywhere between 2-21 days is considered normal).
Typically, eye swelling in your upper or lower eyelid is just an uncomfortable annoyance that will go away on its own within a day. But if the swelling lasts longer, it`s important to treat it because some problems can quickly damage your eyes.
A black eye is bruising and swelling around your eye, usually caused by a blow to the area, such as a punch or fall. It should get better within 2 to 3 weeks.
With clean hands, massage along the length of the eyelids towards the ear (massage upper lid down and the lower lid up) with the eyes closed using comfortable pressure. Massage for 30 seconds and repeat 5–10 times after warming the eyelids. This helps to push the oil out of the glands.
Massage. Massage the eyelids immediately after applying the warmth. Massaging helps to push out the oily fluid from the tiny meibomian glands.
Dogs are good at reading us, and they usually know when we are being affectionate, such as when we kiss them. Because they love affection from us, most dogs do like being kissed. However, they don`t like the act of being kissed but rather that we give them attention and show affection.
It`s not unusual for dogs to grieve the loss of a person they`ve bonded with who is no longer present. While they might not understand the full extent of human absence, dogs do understand the emotional feeling of missing someone who`s no longer a part of their daily lives.
Dog`s eyes can produce tears, but insofar as we are capable of knowing, they don`t seem to be producing emotional tears. They most certainly are capable of expressing emotion, and they typically will express sadness by whimpering or whining or hiding their face. They just don`t cry when they`re sad.
Corneal abrasions generally heal within three to five days. Medication is used to prevent bacterial infections (ophthalmic antibiotic drops or ointment) and to relieve spasm and pain (ophthalmic atropine drops or ointment).
Red eyes in dogs can happen for number of different reasons. Common causes include allergies, an injury, dry eye or a foreign object in the eye. Sometimes red eyes are no real problem. But others need an immediate trip to the vet.
Some injuries may affect your dog`s ability to open its eye entirely. A bloodshot appearance in the white of the eye may indicate trauma or irritation. A yellow or greenish discharge can signal an infection, which may occur as a result of an injury.

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few.

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. My dog licks his feet and legs and they are turning brown. He is a white dog. Can you help?
ANSWER : A. Licking the feet and legs can be caused by a number of things in dogs including allergies, illness or even stress behaviors. Allergies are the most common in dogs, with yeast infections coming in second. Allergies can cause the area to become red and itching, making your dog want to lick and chew on them. Over time, the area may become stained from saliva, especially in lighter or white-coated dogs. Yeast infections are also common between the toes, and may cause a smelly “corn chip” smell to appear near your dog’s feet. Again, dogs will attempt to lick and chew to relieve the itch. Keeping the feet clean and dry can help relieve both allergies and infections and pet wipes or a baby wipe of all paws when your dog comes in from outdoors may also help. Keeping your dog from licking the space with either dog booties or an Elizabethan collar is also good as it will prevent secondary infection and staining of the paws and legs. If your dog is determined to keep licking and keeping the feet clean and dry do not help, then your vet can help by providing a medication to treat any infection or provide relief of allergies.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. I was told by my vet that my dogs cherry eye was caused by something hitting his eye when he was poking around under a bush. I was told surgery needed
ANSWER : A. Prolapsed gland of the eyelid refers to a pink mass protruding from the animal’s eyelid; it is also called a “cherry eye.” Normally, the gland is anchored by an attachment made up of fibrous material. The most common sign of “cherry eye” is an oval mass protruding from the dogs’s third eyelid. It can occur in one or both eyes, and may be accompanied by swelling and irritation. He may have acquired it by getting an injury to his eye but this isn’t the case sometimes. Sometimes there is a weakness in the fibrous attachment.

The veterinarian will review the mass in the dog’s third eyelid and determine if there is an underlying cause for the condition. The diagnosis of the prolapsed gland could be scrolled or everted cartilage in the third eyelid, abnormal cells in the third eye, or a prolapse of fat in the dog’s eye.

Treatment often includes surgical replacement of the gland in the dog’s eye, or removal of the entire gland if the condition is severe. Conversely, if medications are recommended, they are typically topical anti-inflammatory drugs that are effective in reducing swelling.

Q. Rescued a dog almost two weeks ago, and now that her kennel cough is gone her personality shines!! No previous training, how should I start?
ANSWER : A. POST FOUR:

After your dog is familiar with the behavior you lured from scratch, and taught to your dog, you can start to use the “no-reward marker” I talked about. What you do is ask the dog to perform the behavior, and if the dog does not perform the behavior, you simply say your no-reward marker (choose one: eh-eh, hey, uh-oh, oops) show them the treat, put it behind your back, and BRIEFLY ignore your dog. Just turn your back for a second or two, before turning back to your dog and saying, “let’s try that again.” When you’re ready to start over with your dog, make sure you move around. If you are repeating the same cue while in the same position, while your dog is in the same position, you are likely to receive the same results. The more you move around, and start fresh, the better your chances are of having your dog listen to your cue the second time around. BIG rewards when they dog it successfully! Lots of praise and treats.

My no-reward marker is “hey.” When my dog does something wrong I say, “hey” and she immediately understands that she needs to offer a different behavior. This is clear to her. I don’t have to say it in a mean way, I simply say, “hey” in a normal tone of voice and she understands what the word means.

Once you’ve built up that connection and communication with your new dog, you can work on all kinds of fun behaviors! I personally enjoy the more zen-like behaviors: https://www.youtube.com/watch?v=ruy9UMcuGh8

I like to teach my dog fun tricks that offer her a “job” to do of sorts like object retrieval: https://www.youtube.com/watch?v=I4iertZSva8

(object retrieval training completed; what it looks like: https://www.youtube.com/watch?v=jx0Dml28FGY)

Scent-games are fun too! Very confidence building. Hide a REALLY smelly treat in a box, and place that box in a line of boxes. Let your dog go in the room while saying something like “search!” or “find it!” and watch them hunt for that smelly treat! Lots of rewards when they find it!

Q. My dog keep hacking like a cough or something in her throat, what can I do?
ANSWER : A. Hacking and coughing can be caused by a number of things ranging from foreign bodies such as twigs stuck in the mouth or throat, to infections or illnesses such as Bordetella or Kennel cough, common in dogs that frequent kennels, dog daycare or dog parks. In older dogs, heart and lung issues can also be indicated by a cough that does not go away.

If you think there may be a foreign object stuck in your dog’s throat, you can sweep a finger gently through the back of the mouth or throat if your dog will let you. If something feels stuck and is not easily moved by the finger, it is best to contact your vet to have the object safely removed. This usually requires sedation so that your dog does not become panicked or move, causing the object to become further stuck or cut the throat.

If your dog is showing other symptoms of illness in addition to the cough such as runny nose or eyes, fever, lethargy or changes in appetite, it may indicate a viral or bacterial illness such as kennel cough. These are usually treated with a cough medication in severe cases, plus rest and treatment of any additional symptoms until the condition improves. In bacterial causes, antibiotics may also be given to help your dog feel better.

If your dog has a constant cough that does not go away, or has had changes in ability to exercise, breathing, or appears to have swelling around the chest or abdomen, in may indicate a lung or heart issue. Your vet can thoroughly examine your dog for any signs of heart or lung problems and can then offer care as needed depending on the cause.

Q. Why does my dog eat grass?
ANSWER : A. As another user mentioned, dogs can eat grass when they want to vomit. Sometimes, when a dog has an upset tummy, they will eat grass. If you notice your dog eating grass frantically, you can assume vomiting will shortly follow. Grass does not digest and pass normally. If your dog eats too much grass, it can cause serious issues with pooping. Your dogs poop can end up all tangled inside of her, and it can need veterinary assistance to remove it. The same goes for celery, so avoid feeding celery to your dog.

The other day my boyfriend accidentally left the laundry room door open where we were keeping the trash that was filled with cooked chicken bones. She ate one of the chicken bones lightning fast. We had to induce vomiting by feeding her some hydrogen peroxide. After we had fed her the peroxide, she immediately began frantically eating grass because her tummy was upset.

If there is something lacking in your dogs diet, it could be that your dog is eating grass to make up for it. I am sure that my dogs diet is extremely well balanced (I do not only feed her an air-dried raw food-type diet (Ziwipeak), but a wide variety of safe, healthy foods), so when she eats grass, I know that it is because she has an upset tummy.

That is why I think it is important making sure your dog has a very well balanced diet. If your dog is on a low quality kibble, your dog may be trying to let you know by eating grass (or eating poop).

Q. This morning my dog came in and had swollen eyes with mucus coming out. They look bloodshot and he paws at them.
ANSWER : A. If your dog’s eyes are swollen it is possible that illness or an allergic reaction is causing the problem. It is best to keep your dog from pawing or scratching at the eyes as this can make the swelling worse or cause a secondary infection. If the mucus is green or yellow, it may also indicate and infection has occurred. This is usually treated with antibiotics from your veterinarian. Until you can get to the vet, it is best to prevent your dog from pawing at his eyes with an Elizabethan collar. You can also use a warm wet washcloth to remove any excess debris and keep the eyes open. If the swelling worsens or moves to the head, face or neck it may indicate a medical emergency that should be treated immediately.
