How to Take Care of a Month-Old Puppy

By Cate Rushton

Ideally, puppies remain close to their mothers during their first 2 months of life, but that’s not always possible. Luckily, pups abandoned or orphaned at 4 weeks can still grow into healthy, happy dogs with the supervision of a surrogate human. A puppy who has benefited from his mother's constant care and attention for a month is poised to thrive if you'll diligently assume his care.

Your Puppy’s Development

Take your puppy to a veterinarian as soon as possible so he can be weighed and evaluated. A healthy 1-month-old puppy should eliminate waste on his own and attempt to clean himself. He can lap water from a stable shallow dish and is about ready to begin the transition to solid food. By a month of age, pups have fully developed vision and are increasingly energetic and adventuresome. Your pup should be eager to explore his immediate surroundings and will walk, trot, roll around and play. He may be comfortable being alone for short periods of time while confined in the safety of his crate.

Your Puppy's Health

During his assessment with the veterinarian, your puppy may receive his first vaccination, but his immune system is still fragile. You'll need to carefully monitor his health; month-old puppies are in danger of quickly deteriorating if they become ill. Track his weight daily, especially during the weaning process, so you know he’s gaining. Seek immediate medical attention if he seems lethargic, stops eating, or experiences continual diarrhea or vomiting.

Your Puppy's Nutrition

Around four weeks, puppies develop tiny teeth and mother dogs begin weaning them. You'll begin a transition to solid food but provide supplemental bottle feedings. Use a puppy bottle and a milk replacement formula prepared with warm water. Your puppy's weight determines the amount he needs; follow label directions or check with your veterinarian. Bottle feed a month-old pup two to three times per day, and make sure he’s lying on his tummy to avoid choking.

Introduce solid food in a saucer during regular feeding time. Mix canned food with water or formula, or soak dry kibble until soft. Let your puppy lick the food off your finger to encourage him. At first, he may be more interested in playing with his food than eating it, so watch him to ensure he actually eats. Once he's getting adequate nutrition from solid food, you can reduce, then eliminate, bottle feeding.

Your Puppy’s Environment

Provide a month-old fostered puppy with a crate for sleeping and quiet time. Purchase a crate that will accommodate his adult size and modify it by placing rolled towels along the sides and in the end so that he has just enough room to stand up and turn around comfortably. Place the crate in an area of your home where he’ll be near the family, and include a soft blanket and a few toys for chewing. Keep your puppy in his crate at night and during the day when you’re unable to supervise him. Let the puppy join you in your room at night, in his crate.

Keep your puppy clean by wiping him down with a warm, damp washcloth or gently brushing him. You can begin introducing regular baths, provided that the room is warm and you dry him thoroughly afterward.

Your Puppy’s Socialization

By the fourth week, and for the next 10 or so, your puppy’s experiences with the outside world play a large role in his development. Puppies who don't live with their siblings and their mother until age 8 weeks can develop problem personalities. You'll counter this by spending lots of time playing with him, "his way" -- but you'll have to correct improper biting and mouthing, which are common among abandoned baby pets.

Since a month-old puppy has not had a full series of immunizations, keep him away from strange dogs. But introduce him to different environments to socialize him. Let him meet a variety of people, including children, so he associates humans with petting and play. He’s too little to walk on a leash, but you can take him for adventures in your arms and introduce to the sounds of cars, sirens, barking dogs and other loud noises.
