Severe squinting with spasms of the muscles around the eye is a symptom of a
painful eye. Any painful eye condition can cause squinting. The tightening of
the muscles rolls the eyelids in against the eye.
Once rolled in, the rough edges of the lids and the hairs rub against the
eyeball, causing further pain and spasms.
Treatment: Anesthetic drops can be applied to the eyeball to relieve the
pain and break the cycle. The relief is temporary, unless the irritating factor
is identified and removed.
is characterized by frequent loose or liquid bowel movements. It can be caused
by something as simple as a change in diet or a more serious illness or
infection. Diarrhea may be sudden in onset and short in duration. It can also
last for weeks to months or occur off and on. A single bout of diarrhea is
generally not a cause for concern in dogs-but if it persists for more than a
day, it can lead to dehydration , may indicate an underlying health issue and
should be checked...
Bacterial blepharitis isa condition in which the eyelids become thick,
reddened, inflamed, and encrusted. Mucuslike pus may adhere to the lids.
Blepharitis in puppies occurs primarily in association with puppy strangles. In older dogs
it can be associated with various skin diseases, including canine atopy, demodectic mange, autoimmune
diseases, and hypothyroidism.
Staphylococcal blepharitisoccurs in both puppies and adults. It is
identified by small white pimples on the edges of the eyelids. The pimples
Treatment: Blepharitis is treated with oral and topical antibiotics. To remove adherent
crusts, use a washcloth soaked in warm water as a daily compress over the
eyelids. Three or four times a day, apply a topical ophthalmic ointment or
solution containing neomycin, bacitracin, or polymyxin B. Your veterinarian may
prescribe an ophthalmic ointment that contains corticosteroids.
Blepharitis is difficult to cure. Some dogs require long-term treatment.
Dogs with chronic blepharitis should be checked for hypothyroidism. Any primary
cause will need to be treated.
Foreign Bodies in the Eyes
Foreign material such as grass seeds, dirt, and specks of vegetable matter
can adhere to the surface of the eye or become trapped behind the eyelids. Dogs
who ride in the open bed of a pickup truck and in the cars with their head out
the windows are at high risk for getting dirt and debris in the eyes. Thorns,
thistles, and splinters can also penetrate the cornea. This is most likely to
happen when a dog is running through dense brush and tall weeds.
Signs of a foreign body in the eye are tearing and watering, blinking,
squinting, and pawing. The third eyelid may protrude to
protect the painful eye.
You may be able to see dirt or plant material on the surface or behind the
upper and lower eyelids. If not, the foreign body may be caught behind the
third eyelid. In that case, the dog will need a topical eye anesthetic before
it can be removed.
Treatment: Flush the eye for 10 to 15 minutes using cool water, or
preferably a sterile saline eyewash or artificial tears. To flush the eye, soak
a wad of cotton in the solution and squeeze it into the eye repeatedly. If you
have a bottle of artificial tears on hand, you can flush the eye directly from
If the foreign body cannot be removed by irrigation, you may be able to
remove it by gently touching it with a wet cotton-tipped swab. The foreign body
may adhere to the cotton tip. Foreign bodies that penetrate the surface of the
eye must be removed by a veterinarian. Restrain the dog from pawing at the eye
while you drive to the veterinary hospital.
If the dog continues to squint or tear after the foreign body has been
removed, have him checked by your veterinarian to see if the cornea has been
