What is ARG:
Disorder which requires medical treatment; In some cases, gastritis can be extremely severe and cause associated secondary health conditions; so it is imperative that any onset of gastritis be treated promptly

It is important to understand that gastritis can quickly turn into a life-threatening condition for dogs when left untreated

Most cases are mild and only require minimal antibiotic treatment, the threat of ulcers and stomach cancer is real; so dog owners need to be aware of the signs and symptoms of gastritis in dogs, which can include:

  1. Persistent vomiting with or without blood
  2. Excessive diarrhea which may be black
  3. Sudden weight loss
  4. Decreased appetite
  5. Weakness and fatigue

Treatment:
ARG treatments range from triple to quadruple therapy:

  1. Amoxi, metronidazole, carafate +/- bismuth
  2. Clarithromycin (if you can get it) and amoxi, carafate +/- bismuth
  3. Metronidazole, Tetracycline, Doxycycline, Tylosin, Azithromycin

These are all antibiotics with or without weak anti-inflammatory effects

These drugs may be used alone or in conjunction with other more potent anti-inflammatory drugs

These antibiotics may modulate or alter bacterial populations within the intestine and may allow a lower dose of the other anti-inflammatory medications to be used

They may be used alone in animals suspected to have bacterial overgrowth or so called antibiotic responsive gastroenterocolitis
