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.
Young puppies have short attention spans but you can expect them to begin to learn simple obedience commands such as âsit,â âdown,â and âstay,â as young as 7 to 8 weeks of age. Formal dog training has traditionally been delayed until 6 months of age. Actually, this juvenile stage is a very poor time to start.
