The Latin abbreviations i.e. and e.g. are often confused. Used incorrectly, they achieve the exact opposite of the writer's intention, which is to appear learned by marshaling a Latin phrase for an English one not all that much bigger.
Most dogs are pregnant for between 58 days and 64 days. The due date varies slightly depending on the breed and size of dog as well as the size of the litter she is carrying, but vast majority of dogs will give birth on the 63rd day. If you know the date your female dog mated, you can count 63 days from that date
After your dog gives birth, she could have 8 to 12 puppies to nurse and occasionally more than 12! Since all these bodies need to grow, your girl will need special attention to her diet. Nutritional deficiencies in pregnant or nursing dogs are most likely during the first 4 weeks of nursing.
