You cannot know if a dog has brucelliosis without a blood test. It is a disease that affects reproduction, you would not "see" symptoms. You need a veterinary opthamologist to check for the first signs of PRA because there would only be minor changes to the retina at first and you would not notice any symptoms until the dog is older, that is true for other eye issues as well. It is also nice if you can get a cardiologist to listen to the heart as they are trained to hear slight murmurs, again heart problems may not be symptomatic until the dog is older. There are many progressive diseases in dogs that are not symptomatic but sometimes the indicators of a possible problem can be detected via screens and tests. |
