Dog aggression issues are quite common in many dogs of terrier descent, especially those breed for combat with other dogs. Sounds normal in that respect. Removing her eye (for whatever medical reason it is needed) will not effect that in either direction
Yes heartworms can present in the eye. FYI
Severely infected dogs may show signs of heart failure, fatigue, coughing, rapid heart beat, enlarged liver, loss of appetite, fainting, or jaundice. Occasionally, heartworms may also be present in the eyes, abdominal cavity, and even the spinal cord.
I'm sorry you're having to go through this especially since the prevention of Heartworms is so simple.
However having an eye removed if it's necessary could present more problems if she is already DA (dog aggressive). It will not make her more DA but could cause problems where she is more jumpy and in turn more problems with the other dogs in the house. Some dogs who lose an eye can be startled by someone or another dog on the blind side and some dogs will take that fear and strike out. I am a dog trainer and behaviorist and have seen this many times. Now the dogs temperament issue was already there to begin with but the loss of an eye (loss of sight) could aid in the grumpiness of the dog.
Now if it was my dog, depending on the cost and outcome I might opt to have the eye removed. But your problem lies in the temperament of the dog which should have little to do with the surgery. So the bigger question is what problems with the other dogs is she having? Then we can help on some tips to make peace in the house surgery or no surgery.
