For example, if you aren t sure if your dog s ear should be quite so red, check the other one. It could also have an infection, but usually the ears will look at least slightly different if there is a problem. If those ears have a lot of hair like Cockers or Poodles they have an increased chance of infection. If your pet is very sensitive about having the ears touched or tilts his head, there is a reason. The eyes should be clear with no discharge either.
Eyes can go from having a minor problem to a big problem in hours.
Rub and massage your dog all over, including running your hands down the legs. Again, in most dogs you have two front legs to compare, two sides and two back legs. Any unusual lumps or bumps may merit a closer examination. With a regular routine you will learn which small growths have been there and been checked out by your veterinarian and which are new or are growing rapidly. At this time you can also check your dog s weight.
