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.

Keratitis conjunctivitis or dry eye may cause the accumulation of slimy green mucus on the eye of a dog. Canines could suffer from excessive tearing as a consequence of abnormal lashes, glaucoma, or conjunctivitis infections.
3 weeks before your dog passes you may notice: increasing weight loss, picky eating, a change in respiration patterns, less interest in pleasurable activities, increased self-isolation, eye discharge and skin problems.
There are many reasons dogs can develop conjunctivitis and red eyes, with infections being just one of the possibilities. Allergens, such as tree, grass, flower, and other pollens, can cause itchiness, redness, and discharge in dog eyes. Allergies are one of the most common causes of red eye in dogs.
What are signs of canine influenza in dogs? The signs of this illness in dogs are cough, runny nose, fever, lethargy, eye discharge, and reduced appetite, but not all dogs will show signs of illness.
Your dog`s eyes shouldn`t be red, and they shouldn`t show any signs of eye discomfort, such as rubbing, squinting, blinking, or sensitivity to light. If at any point you notice an increase in your dog`s eye boogers or other worrisome symptoms, make an appointment with your veterinarian.
If you notice your dog squinting in one eye, it could be a sign of dry eye. Other signs of dry eye include redness of the eye, excessive mucus-like material on the cornea and ocular discharge. If you suspect that your dog has dry eye, take it to your veterinarian for an exam.
The medically correct term for dog eye gunk is discharge. Clear to whitish-grey eye gunk with a watery consistency is normal in most dogs. You may notice some dust in them as well.
Answer: Fortunately for us, dogs do not understand they are going to be put down and what happens after they are given the injection that puts them to sleep. I assume that dogs who are put down though feel loved or at least feel reassured by our presence if we are close to them, pet them and talk to them.
If a dog`s eye is swollen, several health issues could be causing it, including allergies, injuries, infections, or abscesses. Regardless of the cause, you`ll need to head to your veterinarian for treatment. Ignoring it is never the answer because it can be painful for your dog.
The white portion of the eye (sclera) can appear red when the vessels on the surface become enlarged. This may result from mechanical irritation, environmental irritants (such as extremely dry air, excess sun exposure), allergic reactions, infection, and other medical conditions.
Canine influenza is a viral infection that primarily affects dogs, but can sicken cats, too. Currently, two strains have been identified in the United States: H3N8 and H3N2.
There is no cure for dog flu. Treatment is supportive, and your veterinarian can advise you on the best ways to keep your dog comfortable during his illness and recovery. Some dogs may require supportive care, such as fluids, to aid their recovery, as well as nonsteroidal anti-inflammatory medications to reduce fevers.
White or cloudy dog eye discharge: Dogs with cloudy or white eye discharge likely are experiencing eye inflammation rather than infection—a common culprit is allergies. Eyes might also appear inflamed due to corneal ulcers, dry eye, or a foreign object irritating the eye.
Pink eye is notoriously contagious in humans, but luckily, Graham says most cases in dogs are not contagious to people or other dogs. However, as always, it`s best to consult your veterinarian about your dog`s specific case to determine how careful you should be until their conjunctivitis clears up.
Certain breeds of dogs are known for having a `normally` increased eye discharge. Rottweilers and English Bulldogs have more goopy eye discharge and small breed dogs such as Toy Poodles and Chihuahuas often have a brownish or clear discharge.
Just like with humans, puppy bloodshot eyes are caused by blood vessels rushing to the scene of irritation or infection. This can happen as part of an overall eye problem or as a response to stress.
The third eyelid has a cartilaginous frame and a gland at its base, which is responsible for producing 30-50% of the aqueous tear film. The gland is very loosely attached to the third eyelid and in some dogs it pops up from behind the edge of the third eyelid, looking like a red cherry hence its nickname `Cherry eye`.
Allowing your dog to die `naturally` at home, in a familiar environment, may be less frightening for them. However, it may be hard for you to watch. Alternatively, a great number of veterinarians offer `home visits` to perform euthanasia which avoids the need to travel to the vet`s office.
If your dog is dying, he/she will show a very clear loss of appetite. There will be virtually zero interest in eating and drinking water. As death nears, the organs like the liver and kidneys are slowly shutting down, making your dog lose digestive functions.
The heart and lungs will stop functioning within minutes after injecting the euthanasia solution, so dogs generally won`t feel pain because they are unconscious. They may react to the procedure by having muscle spasms or crying out due to underlying sickness, yet the whole process is quick, simple, and painless.
It may take a minute or two for the heart to stop. The doctor will listen carefully to your pet`s heart to ensure it has stopped before pronouncing him or her gone. After that, there is no danger of your pet waking up. This is a very common fear for pet owners.
There are many causes of a red eye, but all ocular diseases should always be considered an urgent matter, and be checked immediately by a veterinarian.

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.

Q. Why does a dogs pads on his paws turn such a pink color?
ANSWER : A. I’m confused here. Are your dogs paw pads typically black, but they turn a reddish pink? You may want to see your veterinarian about this to make sure there isn’t anything wrong with his paw pads. I’ve met dogs who have extremely fragile paw pads due to some bad genetics.. they end up getting injured on their paws very easily. I’ve met dogs who are unable to even walk on cement without wearing little doggy booties. It could be that your dog is dealing with some serious discomfort, and you want to get that checked out immediately.

If your dogs paw pads just seem a little bit irritated, you may want to try something like “Musher’s Secret” on them. This is an ointment that you rub on your dogs paw pads to keep them healthy, and smooth. I use this in the winter when there is rock salt all over the ground.. it keeps her paw pads from getting irritated and tearing open. It’s like lotioning your skin to keep it from getting dry and cracked. If you think your dog is dealing with something that is a little more extreme than just some dry irritated paw pads, then see your vet immediately instead of purchasing the Musher’s Secret.

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. 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. 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 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. We have a 4 yr old lab-pit mix we raise from 6 weeks.If my husband tries to take hin by the collar and make him go out to pottie he growls.Problem?
ANSWER : A. This is not good behavior. Rather than take him by the collar, call him to come with you. If he’s not good about coming when called, you can work on that. Keeps treats on hand to to entice him out and reward him when he does go potty and he’ll come to look forward to it. Clicker training is another great way to teach a dog all kinds of things, from obedience to tricks.

Have treats on hand that you know he loves, then simply click and treat. He will come to associate the sound with getting a treat. Start putting distance between you so he has to come to you. Call and click and when he comes to you for that treat, treat him and give him lots of praise. Move to hiding somewhere in the house, call and click. When he comes to you reliably inside when you call, click and treat. When this behavior is consistent, move outdoors with a very long leash. Call and click, if he doesn’t respond, give a light tug on the leash. If he takes even a single step toward you, click, treat and lots of praise. Keep doing this until he comes eagerly. Next, try him off-leash in a securely fenced area. Call and click. At this point he should be responding well and coming easily to the call and click. If he does not, go back to the last step he performed reliably and work on that again until he responds well. Eventually, you can start not treating him every time, but still praise him. Gradually lessen the frequency of the treats until he comes just to the click and praise.

Keep training sessions short, ten or fifteen minutes to start, no more than 30 minutes at a time and do it a few times a day. Try not to do it any time he is overly excited so that he can pay attention to you. Always end a training session on a good note, even if it is just getting him to do something he already does well on command. And never, NEVER punish a dog when they come to you, no matter how far they’ve made you chase them, no matter how frustrated and angry you might be. That teaches your dog that coming to you is a bad thing.

Q. How do I desensitize my dog to squirrels and stray cats in the neighborhood?
ANSWER : A. It depends on the goal that you have in mind. I am going to assume that you would prefer that your dog not chase squirrels or stray cats in the yard/street. In this case, your options include: (1) training your dog on a “Leave it ” cue using positive reinforcement methods, (2) training your dog not to pull on its leash when it sees a squirrel/stray cat, and (3) training your dog to perform a more desirable behavior when it sees a squirrel/cat.
Training your dog on a cued “leave it” command is useful because it will give you the ability to tell your dog to stay away from any number of undesirable objects on your command. Training your dog to perform a more desireable behavior when it sees a squirrel or cat will substitute a behavior you find acceptable (sitting, laying down, coming to the door, etc.) with a behavior you dislike. Your dog can still react, just in a positive way. If your dog pulls on the leash every time you see a squirrel/cat, training not to pull will make your walk safer and more pleasant.
The ideal training method to use with dogs, or any animal for that matter, is positive reinforcement training, particularly a method called “clicker- training.” The basic concept of positive reinforcement training is to pair a reward (reinforcement) with a behavior you want to increase in frequency. In other words, when your dog performs the behavior you desire, it receives an award, which reinforces the desired behavior so you get more of that behavior. There are many excellent books in stores or on-line that describe positive reinforcement training in detail and many give step-by-step instructions for training common commands like “leave it”. Look for books that specifically mention positive reinforcement training or clicker-training. You can also take dog training classes to learn the techniques, find a mentor who already uses clicker-training, or request a consult from one of the pet experts on this site to guide you.
