How to Identify Common Pet Problems ?

Red eye in rabbits is a common symptom that can be caused by a variety of underlying conditions. These include bacterial infections, environmental causes of irritation, damage to the eye such as keratitis, corneal ulcers or dental disease.
Your rabbits` eyes can be vulnerable to bacterial infections. Common infections include conjunctivitis – also called `pink eye` – where the eyes look red and sore with fluid around the rim. For this, your vet will prescribe antibiotic cream or drops.
The most common causes of weepy eyes include dental problems, tear duct disease, eye infections injuries, and irritation. Book an appointment with your vet if your rabbit has weepy eyes, even if they seem ok in themselves – the sooner the problem is treated the better.
Red-eyed in rabbits is only related to albinism if the rabbit has white fur. Red eyes are caused by a medical condition known as hyperemia. Sometimes, hyperemia is referred to as red-eye. Hyperemia is usually a result of inflammation in a rabbit`s eye.
To keep your rabbit healthy and happy throughout their life, you need to understand your rabbit`s needs. Most domestic rabbits can easily live to be 8 years old, and many can live for up to 12 years.
Most cases of conjunctivitis respond to treatment and clear up quickly, but can take longer or require ongoing treatment if there is an underlying cause such as dental disease,. For more information about treating the underlying causes of eye problems in pet rabbits, follow the links within the causes section.
Can you use eye drops on rabbits? You should never use human eye drops on a rabbit`s eyes. These can cause stinging, irritation, and potential damage to your rabbit eye and cornea. If your rabbit does require their eyes to be flushed (consult a veterinarian first), you can use special pet eye drops instead.
Even though rabbits make crying noises, they don`t produce any tears. If your rabbit`s eyes are wet or weeping, she may have a dental disease, allergies, or an infection. Rabbits don`t usually make crying noises when they are sad or lonely. They are more likely to withdraw and stop grooming themselves.
Cherry eye is a term used to describe the popping out of a tear gland in the eyelid. The condition is uncommon in pet rabbits but needs to be treated by your veterinarian as soon as possible.
Typical COVID-19 symptoms in animals include fever, lethargy, coughing and sneezing, eye discharge and gastric problems such as vomiting and diarrhea.
With a good diet and proper care, a rabbit`s lifespan can range anywhere from five to 15 years when kept indoors, said the AVMA`s San Filippo. Ideally, bunnies should be handled and socialized from a young age so they can become comfortable with people.
Even just 30-60 minutes of sunshine in a day can be enough to help a rabbit produce the Vitamin D they need, especially if it`s combined with a healthy, fortified diet. Make sure your rabbit has hay available, which will have some Vitamin D, and pellets that have been fortified with Vitamin D3.
Death is usually within 1-2 weeks after infection, but occasionally animals survive, and signs will slowly regress over about 3 months. Rabbits showing signs of myxomatosis should be seen by a veterinarian as soon as possible.
The infection will usually clear up in 7 to 14 days without treatment and without any long-term consequences. However, in some cases, viral conjunctivitis can take 2 to 3 weeks or more to clear up. A doctor can prescribe antiviral medication to treat more serious forms of conjunctivitis.
Recognized eye color ranges from brown to brown with a ruby cast to dark brown to blue-gray.
The Florida White is a relatively small breed rabbit originally produced for the laboratory or smaller meat rabbit. They are all white in color with no other markings, and have Albino red eyes.
Flush the eye warm salty water- 1 teaspoon of salt per litre is tear concentration. If you have a syringe handy you can use this to gently flush under the eyelid this may in some cases dislodge a foreign body.
It might be he has something caught it in making his eye run. Try bathing it with cooled, boiled salty water (one tea spoon of salt to one pint of water), or saline solution. That might be enough to sort it out. If that doesn`t work then a trip to the vets never hurts.
Rabbits have a retina with a much higher ratio of cylinders to cones compared to the human retina, which allows them to see better in the dark. In fact, we speak of the rabbit as a crepuscular animal because its visual sensitivity, when darkness begins to fall, is very high.
Healthy rabbit eyes are clear and bright. If you pull up or down on the eyelid, the eye tissue should be pink, not red or very pale. Red, inflamed eye tissue and/or discharge from the eyes could be a sign of infection. Very pale tissue can also be a sign of illness.
There are actually many reasons for conjunctivitis in your rabbit. Infections caused by Pasteurella multocida, Staphylococcus, and Treponema cuniculi are all common culprits. Some of these infections may be transferable to humans, and some can even cause your rabbit to lose their eye if not treated.
This can happen when there is inflammation or irritation of the eye, such as with allergies or eye infections. In this case, the excess tears are the body`s way of trying to wash away what is bothering the eye. Another possible cause of excessive tearing is a blocked tear duct, causing tears to collect in the eye.
In an eye with pink eye, the white part looks light pink to reddish and your eyelids are puffy or droopy. You might see fluid (discharge) coming from the infected eye or crusting on your eyelashes and eyelids.
Most of the time, pink eye is caused by an infection — a virus or bacteria. Viral pink eye is the most common type. Pink eye that`s caused by an infection can spread very easily, so avoid passing it to others by washing your hands often and not sharing items like pillowcases, towels, or makeup.

the most relevant questions and answers related to your specific issue

Q. One eye is more red than the other. Last night he was pawing at it,today, he isn’t. Should I bring him to the vet?
ANSWER : A. Sounds possible that he had some irritation to the eye that is at least not itchy anymore. You can do either, having it checked now to confirm mild irritation, potentially due to debris or a topical irritant to the eye; or you can flush the eye with sterile saline eye wash (over the counter) using care not to poke or prod the eye and see if the irritation goes away on its own within the next 24 hrs. It has shown improvement already it appears, however if it is not cleared up and your pet seems irritated by it AT ALL, then it should be looked at by a vet and tested for a possible corneal scratch or ulcer. These can cause redness of the eye, eye discharge and pawing at the face. They are usually treated by prescription only topical eye antibiotic ointment and generally do very well after treatment.

Q. My Pug’s nose is red and he doesn’t have a yeast infection. He is taking medicine for that. It seems to get worse when he goes outside. Any ideas?
ANSWER : A. Redness or irritation can be caused by a number of things including yeast infections as you mentioned, but can also be caused by allergies to the environment, or even cold or hot weather. Dogs with short fur can often get sunburns on the skin, and the cold may also irritate or cause redness when outdoors. Allergies to pollens or other outdoor allergens may also cause redness on the body or nose. An allergy medication from your vet is usually all that is needed to clear this up.

If the redness is happening just when outside, it may also be that your dog is digging or nosing around in something that is irritating. It may be a good idea to watch your dog a few times while he is outside to see if there is anything he enjoys exploring. The redness could just be irritation from that.

However, if you are concerned about the redness, it is always a good idea to bring it up with your veterinarian to make sure there is not a more serious cause behind it.

Q. Bunny has one very red eye, what do I do? he seems really sad also…
ANSWER : A. You can clean the eye with warm, boiled water and cotton wool. If the redness doesn’t go away in the next day or two you should take your rabbit to your vets. Please, note that if your bunny looks unwell and is not eating you should take him/her to your vets without delay.

Q. Weak, discharge from eyes, swelling on right eye, does not want to open eyes. What is wrong?
ANSWER : A. If the discharge from the eye is green or yellow in color, it can indicate a secondary infection. Swollen eyes can be caused by a number of things ranging from allergies to infections, to injury to the eye itself or surrounding areas.

It is best to have your pet’s eye examined by your local vet. They will most likely wish to place a stain in the eye that can check for damage such as cuts or scratches. An ointment can then be given to help reduce inflammation, pain and take care of infection.

Until you can get to the vet, be sure to not let your pet scratch or paw at their eye as this can make things worse. You can also use a warm wet washcloth to gently remove any debris and allow the eye to open some, providing relief. However, if symptoms worsen, or the swelling travels to the face, head or neck, it may indicate a serious allergic reaction which should be treated immediately.

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. Yes I have a Chiquita and her left eye was swollen and red then next it spread to the other eye. What should I do when all the vets are close?
ANSWER : A. If both eyes are swollen shut or you are seeing swelling of the face and neck in addition it may indicate a serious allergic reaction and you should seek care from an emergency vet immediately. It is also best to try and schedule an appointment with your regular vet when they reopen if the eyes are very red or bothered or if the redness spreads. You can use a warm washcloth to remove any debris from the eyes to make them more comfortable, however seeking veterinary care is best.

Q. What can be given to dogs to stop the brown draining around dogs eyes? I was told tetracycline would work.
Thanks
ANSWER : A. Eye leakage is normal in some breeds of dogs, especially those that are more “bug-eyed” types. This eye leakage is just normal tears coming from the eye which can stain lighter colored coats. Unless there is an infection it does not need to be treated with antibiotics. Signs of infection usually include drainage that is thick or goopy and is yellow or greenish in color. Dogs with infections may also want to keep the eye closed, or may paw and scratch at it.

For plain tear-staining. Tear-stain wipes can be used around the eyes to remove the stain and bring the coat back to natural color. If infection is suspected, it is best to have your vet take a look at the eye prior to placing any medications in it.

Q. Yellow lab F, approx 9-10 yrs. Sudden onset of extreme redness in one eye, now seems to have spread to other over 24-48 hrs. Healty, active, good app.
ANSWER : A. This could be a bacterial conjunctivitis. Dogs can pass these infections around, just like people can. The fact that it started in one eye and moved to the other suggests infection, but I can’t rule out something more serious like glaucoma. I feel like anytime a dog’s eye gets acutely red like this it’s cause for alarm, and needs to be checked out as soon as possible. Like I said above, it’s likely a simple eye infection, but get it checked out to be sure.
