Then there are times when your dog may be seriously ill and need to see the vet right away. A sick dog will look thin, have low energy and have an odd coloring to him. There are some signs that you can look out for to answer this question.

The problem is that it can often be difficult to tell the difference. His gums may be white, blue or yellow. You might go back and forth between trying to decide whether he needs to go to the vet or not. One of the first things to look at is your dog's appearance. If he is seriously ill then waiting could cause him unnecessary pain and suffering, but if he is not seriously ill then the vet bill could be a needless expense. You can tell a lot just by looking over your dog's general appearance.

There are times when your dog may be feeling a little under the weather and a little TLC is all that is needed to get him through it. So, how can you tell if your dog needs to go the vet.

He will seem different than usually with far less energy and not have interest in things that usually.
