Poor Sasquatch (I love his name!). I see what you mean about his very swollen eyes. There could be a couple of reasons why they are swollen. He could be having an allergic reaction to something outside, he could have injured his eyes, or he may have an eye infection. Given how suddenly it came on and how swollen they are,I would give your vet a call now to see if they can get him in for an appointment today. When eye problems come on suddenly, I always advise an immediate vet visit because of the delicate nature of the eye and it's important. Just in case there is something his eyes, you can try gently flushing them with some sterile saline, but definitely get him into a vet. Best of luck, I hope this helps!

We got our Great Pyrenees today! He is just two months old but as the day has been progressing we noticed his eyes get more red. Is this normal ? Is it allergies ?? Do we go to the vet ASAP or can it wait for Saturday ?
Congrats on your new puppy, Apollo is so cute! I would take him into the vet first thing Monday morning. It's concerning that his eyes are getting more red, and that's not normal. Any eye problem needs to be checked out promptly as leaving it untreated can lead to vision loss. I hope this helps!

Dogs eyes are randomly swollen hes acting completely normal
Oh my, poor Lamar! I can certainly see the prominent swellings of both of his eyelids. One of the most common causes of eyelid swelling is from an allergic reaction. The tricky part with allergic reactions is that we often aren't able to figure out the trigger - whether he may be reacting to an insect or spider bite, pollens outside, or countless other things. However, since it looks as though Lamar is missing a good bit of hair around his eyelids (although this could also be pigment change and some glare in the picture), other possible causes could be infectious issues, like mange. Certainly other skin lesions or itching would make this scenario more likely. Since it's most concerning that he's possibly experiencing an allergic reaction with swelling on his face, you really should take him to an emergency vet right away for evaluation and treatment. Some allergic reactions can progress to anaphylaxis, which can cause severe breathing difficulties. I hope that he's feeling better soon!

My 7 month old Bullmastiff/Great Dane is having problems with his left eye. His right eye looks straight at me but his left eye seems to roll back into his swollen eye lid. It is also red and quite watery and looks as though it is blanketed by a thic

Hello, I have a 9 week old Australian Shepherd. She seems to have a very watery right eye and it looks swollen on the far left corner. She also seems to be squinting that eye. What could be going on? And what can I do to help?
Poor puppy! Squinting the eye is a sign of pain. From the photo, the only red thing I see is the third eyelid and that looks inflamed. I am concerned that your puppy has either scratched her cornea, is getting a nasty eye infection or has something stuck under the third eyelid. There’s nothing you can do at home for a scratch or infection other than make sure the puppy does not rub the eye as that will make it worse. An elizabethan collar should be worn at all times to protect the eye. I recommend to have the puppy seen today as it likely is uncomfortable. The doctor will use a special dye to check for an injury to the cornea. You pup will likely get eye medications pending diagnosis. I hope this is helpful and please feel free to post any additional questions. I’m not sure if this is reposted by accident!

I own a great Dane mix and she is 13 weeks old. Her right eye is swollen and she's been having diarrhea
Poor Baby! The swollen right eye could be due to an injury or an eye infection. The diarrhea could be due to intestinal worms, GI illness, a change in diet, eating something rotten, or a foreign body. Given the eye problem, she will need to see a vet first thing in the morning. Any eye problem needs to be checked out promptly, as leaving it untreated can lead to vision loss. Please take her into a vet first thing the morning, where the vet can treat her eye and the diarrhea. Best of luck.

Dogs eyes are swollen
Yes, I see what you mean in the picture, George's eyes are swollen. More specifically, it's the skin around his eyes that are swollen. This can be a sign of an infection, an injury, or an allergy. Any eye problem is an emergency because leaving it untreated can lead to vision loss. Please take him into a vet now to get this diagnosed and treated. Best of luck.

Hey I recently was gifted a French bulldog Pitbull mix it is still young only a few months old but I noticed it has a swollen right eye I was wondering if it could be cherry eye which is common in those does or could it be blindness? What do you thin
Oh dear! I agree that his right eye looks quite enlarged compared to the left. This does not look like a cherry eye (proptosed tear gland), as this usually appears as a localized pink swelling in the inner corner of the eye. This looks more like the eye globe itself is swollen or enlarged for some reason. I can't say what might be causing this without being able to do a full ophthalmic exam, but some possible causes would include acute glaucoma, a birth defect, or some type of trauma to the eye or surrounding issues. I would recommend having this checked by a veterinarian as soon as possible to determine what's wrong with the eye and see if it can be treated.

My Belgian malanois, Mechelen, has had an issue with his left eye for 2 days. Tuesday night we noticed it seemed a bit swollen. I put a cold compress on it thinking he may have hit a branch running. Well this morning it is much larger. I slept with h
Thanks for using Boop by Petco! This is concerning and could be due to conjunctivitis as you pointed out though other possibilities such as a foreign body reaction, corneal ulcer or laceration or even inflammation of the periocular structures could also be going on. Regardless, this does warrant a visit to your veterinarian as soon as possible as he is likely painful. They would be able to examine his eye closely and start therapy based on findings. Good luck and have a great day!

Took alpha walking and his eye is swollen
Poor Alpha! The most common reasons for swollen eyes are bee strings/bug bites or an allergic reaction (of which you generally never know the cause). Trauma or something stuck in the eye could also cause swelling in the area. Carefully check the area for any stingers or marks. You can apply a cold (not cold) compress to the area. Unfortunately, unless you find a stinger, you won't know the cause. You must also protect the area from rubbing with an elizabethan collar since rubbing could make it worse. I recommend to play it safe and have Alpha examined by the veterinarian today. The doctor will check the eye as well as look for clues as to the cause. If an allergic reaction is suspected, he will likely receive an injectable antihistamine and possible a steroid or anti-inflammatory. Just like with humans, some pets may experience an anaphylactic reaction. Monitor your dog for signs of an allergic reaction, such as difficulty breathing, general weakness or a progression of swelling. If y

Mickeys eye is swollen and he seems sleepier than usual. Appetite is fine and he's eating okay. He had diarrhea yesterday but today his stools were fine. His eye was fine yesterday, however. He isn't pawing at the eye or scratching it but he squints
Thanks for using Boop by Petco! This could be due to an eye injury or conditions such as a corneal laceration, corneal ulcer, conjunctivitis, uveitis, dry eye (also known as KCS), among many other conditions. I highly recommend that you have Mickey evaluated by your veterinarian for further assessment and treatment. Further therapy would be based on the findings. Good luck and best wishes!
