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.
Legal limits on the age of puppies when sold. In most cases these laws stipulate that puppies should be over 8 weeks old when they go to their permanent homes. So what is the purpose of this legislation and why is 8 weeks so important.
