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.
The majority of peptic ulcers are caused by a bacterial infection of the stomach called Helicobacter pylori. This infection is often asymptomatic and can be acquired in childhood. The other cause of ulcers is the regular use of aspirin and anti â inflammatory medicines.irst off, let's not buy into the myth that ulcers are caused by a bacteria called H. pylori. Just not true. Ulcers are caused by the prior use of a medication that destroyed your mucosal lining, thus leaving your stomach tissue exposed to your own digestive acids, which then eat a hole right through the flesh.
