Identifying the different signs of sickness in a pet such as dog can be a bit challenging, even for pet owners who are highly vigilant. Since as a dog, especially when he is sick would never be able to communicate verbally what hurts pet owners need to pay close attention to pinpoint the signs of sickness. The subtle changes in their appetite or behavior might be symptomatic of underlying health problems. While they may not be able to say when they are sick, their physical symptoms and behavior changes when they try to communicate.
Another challenging thing is determining the time when to go to the doctor. Some of the most common symptoms of an illness are diarrhea or vomiting. However, dogs may still vomit occasionally even without feeling ill. Drinking water too fast or eating quickly may cause them to vomit, though they may just feel better afterwards. So how could a vigilant pet owner determine when his dog actually needs some veterinary care? Bloody vomiting, profuse vomiting, lethargy or anorexia concurring with vomiting needs an immediate medical intervention. Diarrhea or vomiting for over 24 hours is one sign that the pet needs veterinary care. And having diarrhea or vomiting for an extended period might be a symptom of many things such as pancreatitis, ingestion of foreign material, infections, poisoning, and other serious causes that need an urgent veterinary care.
