Puppies are typically vaccinated at eight and 10 weeks, kittens at nine and 12 weeks, with an initial course of two injections. Your young pet should then be given a booster 12 months after their first vaccination. Rabbits need regular vaccinations too.
How long a stress test lasts depends entirely on what type of stress test you are planning on having. The shortest of all the stress tests are the simple exercise treadmill test without imaging. This type of test is usually pretty quick. You'll only be on the treadmill for ~15 minutes.
This exam is also known by the names cardiac SPECT, myocardial perfusion SPECT, thallium stress test, nuclear stress test, treadmill test and stress perfusion test (vasodilator, pharmacologic). An MRI cardiac imaging study with stress is similar, requires the same preparation, and takes about four hours.
