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 ulcers can be caused by a number of factors. Stress increases the stomachâs output of acid, which can erode the stomachâs lining. Long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), a type of pain killer, can also increase acid production, and itâs well known that a diet of spicy and citric foods can result in ulcers. Some factors are outside of lifestyle changes, however. Many peptic ulcers are caused by a bacterial infection known as Helicobacter pylori.
