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.
In puppies less than 8 days of age, either local anesthetic or no anesthesia is used. If the puppy is over 8 days of age, many veterinarians delay the procedure until the pup is at least 8 weeks of age. At that time, general anesthesia is needed to induce unconsciousness, complete control of pain, and muscle relaxation.
