Firstly, our pets can't speak, they cannot tell us if they feel off color or unwell or have any other indicators of internal illness. We need to examine them every year as well as run some routine screening tests to detect underlying disease BEFORE it is clinically apparent. Secondly, pets will actively mask signs of illness until late in the course of disease. This stems from survival instincts in a pack or colony situation. Use the age chart below to find your pets age in "people" years and the screening testing recommended for each stage of his or her life. We believe the following tests give us the best chance of helping your pet's live longer, healthier lives. These are approximations and may vary by gender, species and breed.
