In todayâs world, weaning is not done to aid the mother. Rather, it is done because puppies generally make their way to their new home at about seven weeks of age, and since their mother is not going with them, the pups need to have their gastrointestinal tracts accustomed to eating commercially prepared foods.
Causes of stomach ulcers. Stomach ulcers are usually caused by Helicobacter pylori (H. pylori) bacteria or non-steroidal anti-inflammatory drugs (NSAIDs). These can break down the stomach's defence against the acid it produces to digest food, allowing the stomach lining to become damaged and an ulcer to form.
Peptic inflammation is inflammation caused by stomach acid. Inflammation may be in the stomach; in the first part of the small intestine (the duodenum), as acid flows in with food; or in the lower gullet (oesophagus), if acid splashes up to cause 'reflux oesophagitis'. A peptic ulcer is an ulcer caused by stomach acid. An ulcer occurs where the lining of the gut is damaged and the underlying tissue is exposed. If you could see inside your gut, an ulcer looks like a small, red crater on the inside lining of the gut. A stomach ulcer is one type of peptic ulcer.
