Ulcers themselves are not infectious, but they can be caused by infections. For example, peptic ulcers are often associated with the bacterium Helicobacter pylori, which can be transmitted through contaminated food or water. Additionally, some ulcers can result from the use of nonsteroidal anti-inflammatory drugs (NSAIDs) or excessive alcohol consumption, rather than an infectious agent. Therefore, while the underlying cause may be infectious, the ulcers themselves are not contagious.
there are many kinds of ulcers including peptic ulcers, mouth ulcers, Corneal ulcers and possibly more.
About 80% of all ulcers in the digestive tract are duodenal ulcers.

That depends on the type of ulcers -- gastric ulcers? sores or ulcers on the skin? Your Vet is your best bet for diagnosing the cause, and proper treatment, of the ulcers.
Gastric ulcers do not have a specific incubation period like infectious diseases, as they are not caused by a pathogen that requires a period of replication before symptoms appear. Instead, gastric ulcers develop due to a combination of factors, including excess stomach acid, the presence of Helicobacter pylori bacteria, long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), and lifestyle factors. Symptoms may develop gradually over time as the ulcer forms and worsens.
