Let's take a look at how you know if you have a sick dog and what defines dog symptoms. Symptoms for dogs are like signs. They are not canine diseases, they are hints to let us know that something is wrong with our dog.
Sick dog symptoms may be physical or they have be behavioral, for example a dog may be limping (physical) or our pet may be acting depressed and not wanting to run or play as usual (behavioral).
Paying attention to the normal behavior and activity of your dog will help you notice when something is just not right. For just about every canine health issue, the earlier you can catch it and allow veterinarian care the better the chances are for your dog to have a fast and successful recovery.
For this reason, it is best to not dismiss any small dog symptoms. This section of SmallBark is designed to help you know what could be the possible causes for whatever is ailing your dog. You will then either relax a bit understanding that it is not cause for alarm or you will be better informed when bringing your dog to the veterinarian.
In some cases, it is your dog's behavior which is the most telling sign. many sick dogs who are in pain will instinctively act aggressive; even those who are normally very affection and docile. They do so, because they feel vulnerable when sick. A dog may retreat to be alone and not want any one to touch them.

It is important to not just understand the symptoms, but for an animal specialist to locate and confirm diagnosis. Once a disease is diagnosed, proper treatment can be administered and this is what is most important.
Never ignore signs. Since your dog cannot speak to you, it will be your job to notice when something is wrong.
Since telling your dog's veterinarian what is wrong will greatly help him or her diagnose an illness faster, it is suggested to take notes. Jot down reminders to show to the vet, to let him or her know who often something happens, what your dog was doing at the time, if there were any secondary issues, etc.
Keeping regular vet checkup visits, feeding your dog high quality meals, providing a warm and comfortable living environment and puppy-proofing or dog-proofing your home can help you keep your dog healthy.
Remember, your dog cannot tell you what is wrong, you must take notice and then take action. We do hope that you find this symptom checker helpful and we wish the best to you and your best friend.
