Many questions which often come up regarding dog diseases or the dog's curious sexual behavior (what to do during the long mating period or when to inhibit him?), his many afflictions (why, all of a sudden, does he suffer diarrhea?), or what veterinarian to choose are all answered here as would be done by any veterinarian in his office. Therefore, you should have some practical ethology (the branch of zoology that studies the behavior of animals in their natural habitats) because being able to understand the animal in itself already helps avoid a lot of unnecessary suffering.Also, at times the question of whether you should treat an affliction at home or take him to a veterinarian. My answer is, if in doubt, take him to the pro. However, it is useful for anyone who has a dog to know what to do in critical situations, for example when he suddenly starts vomiting or shows signs of awkward behavior..
