Females weigh an average of 33-40 lbs and males are slightly larger (average 34-47 lbs). Coyotes can attain weights of 50-60 lbs. Because of their thick fur, weights of coyotes can easily be over-estimated. Due to their canid-like appearance, domestic dogs, red foxes, and gray foxes are often mistaken as coyotes.
A dull or burning pain in the stomach is the most common symptom of peptic ulcers (stomach ulcers). Causes include long-term use of NSAIDs, an infection with H.pylori, or both. Rarely, tumors cause peptic ulcers.
Another major cause of ulcers is the chronic use of anti-inflammatory medications, such as aspirin. Cigarette smoking is also an important cause of ulcer formation and ulcer treatment failure. The major symptom of an ulcer is a burning or gnawing feeling in the stomach area that lasts between 30 minutes and 3 hours.
