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.
These are based on the dogâs estimated size at maturity. Dogs under 60 pounds: Start running when the pup is 6 to 8 months old. Dogs between 60 and 100 pounds: Start when the pup is 8 to 12 months old. Dogs more than 100 pounds: Wait until the pup is 12 to 18 months old. This is just a rule of thumb from one veterinarian who runs with his dogs, but I like his advice.
