Updated May 09, 2016. Cecum cancer is a type of colon cancer, but the signs and symptoms of this disease are sometimes elusive. The cecum demarcates the beginning of your large intestine. This pouch-like section of intestine connects a portion of the small intestine, called the ileum, to the ascending colon.
Most good breeders don't let their puppies leave until around 8 weeks of age (and in toy breeds, 10 or 12 weeks), which means that your puppy may not have been leash trained prior to you picking him up. For large breeds, this may not be the case.
While you can start taking puppies 5 or 6 weeks of age outside to encourage elimination, true housebreaking should start around 7 or 8 weeks. This is the age at which puppies are able to start understanding routines and rules, so the learning process is easier for them to comprehend.
