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.
Give puppies safe chews made for puppies. Puppies even as young as 7 weeks old want to chew. Their puppy teeth begin to erupt at 3 weeks of age, and by 6 to 8 weeks, they have all their baby teeth. At 7 weeks old, puppies are still in the litter and learning to chew with their littermates.
