Bleeding From the Eyes and High Blood Pressure in an Older Dog

by A reader

Reader Question
My dog is a little over 10 years old, a multicolored Indian mixed breed. She is very moody and doesn't allow anybody to touch her. Our vet says she is very timid and gets stressed easily, so she attacks out of fear. She came to us at about 10 days old during a very hard time for our family, and she became the best friend of my children, who are now grown. Now we have six more pets, but she is the senior. For the last few months, I have noticed blood coming from her eyes now and then. It is not regular. Our vet thinks she has high blood pressure and prescribed a daily tablet. It has worked well, but my question is: will she be all right after a certain time, or should this medicine be continued without stopping? Her eyes became red again a few days after the medicine was stopped as prescribed, and as soon as it was restarted, they improved.


Answer from Our Team

High blood pressure can cause bleeding in the eyes, and if the bleeding stops with treatment, that strongly suggests blood pressure is the cause. In dogs, high blood pressure is usually caused by another condition, most often kidney disease, and also Cushing's disease, diabetes or thyroid problems. Treating it usually needs to be lifelong, unless the underlying cause can be cured.

Please ask your vet whether she should stay on the medicine long term, and about blood and urine tests to look for an underlying cause. Regular blood pressure checks help the vet set the right dose. Don't stop the medicine without your vet's advice, since high pressure can come back and damage the eyes, kidneys and brain.

For a fearful dog, ask about medicine to give before vet visits to reduce her stress, and about doing blood pressure checks when she is calm, since stress can make the readings higher.
