Adhesion of the dog Anus
An uncared-for, long-haired dog can not defecate even though he tries really hard. What's probably the problem is that his anus is stuck together (adhesion). The surrounding hairs are so tangled and intertwined with all the dried feces that it is impossible for the feces to come out. Cleaning the area is, mind my words, a very sickening procedure, yet it needs to be done.Dog Vomiting
Dogs vomit very easily. For that, occasional vomits shouldn't be a matter of alarm.
Sometimes, some apparently healthy and well-educated animals start dirtying the with their vomits. If you are convinced that your dog is not suffering from any sickness, has no fever, is seemingly appetent and in a good mood, you might want to consider neurosis.
