Size and Appearance of a 4 Month Old German Shepherd

Once a German Shepherd reaches four months of age, it can be one foot tall and will weigh about half of the total adult weight. Male German Shepherds will weigh between 35 and 40 pounds, while females will weigh between 31 and 35 pounds. Between months three and four of life, a German Shepherd will gain around 10 pounds of body weight, and this will cause a difference in the dog's size and appearance.

At this age, German Shepherds will be growing quickly, and you will be able to notice differences in the dog's size month-by-month. A four-month-old German Shepherd will no longer look like a puppy, and it will more closely resemble an adult by this age.

Once the dog reaches four months old, the coat will be different from that of a puppy, and the dog will shed much more. The coat will become thicker and glossier, and the exact texture might depend on what foods the dog is eating.

German Shepherds come in a variety of colors that include black, white, gray, black and tan, black and red, black and silver, and sable. The coloring of your dog will depend on the breeding and parents.

Additionally, the dog is teething at this age. The German Shepherd will be teething until about seven to eight months, and during this time, the milk teeth will be replaced with larger adult teeth.

German Shepherd puppies tend to have ears that lay flatter, while the adult's ears will be perky and stand straight up. At four months, the process of ear perking will begin, although the cartilage will not strengthen for another month or two. This means that the ears can perk up, then flatten, then perk up again until they become permanently lifted in adulthood.

The dog's ears can remain flat if they live somewhere with consistently loud sounds, as they will try to avoid damage to their hearing by listening to these noises. To allow the dog's ears to perk properly, it is important to keep your dog away from loud, abrupt noises that can negatively affect their hearing.

Activity and Behavior

Four month old German Shepherds are very active puppies that must be stimulated physically as well as mentally. Some great activities to do with a dog include playing outside, playing with toys, going on walks or jogs, dog sports, and attending obedience training.

A four-month German Shepherd will enjoy going on walks for about a mile at a time, and it is preferable to go on several shorter walks throughout the day rather than going on one very long walk.

About two hours of active playtime per day is important for your puppy. Playtime is when they are both physically and intellectually enriched, and it is vital for development going into adulthood. For the first four months of life, there are many new experiences and adventures that your dog will learn from, so it is important.

Sleeping Needs

Sleep is extremely important for a young German Shepherd, and if the dog is not getting enough sleep, it might start to misbehave. If you notice this, it is important to discuss working out a proper daily schedule with your veterinarian, as it will often be a fix that you can make yourself by changing your routine, walk schedule, eating times, or play times.

At the age of four months, a German Shepherd will sleep for around 18 hours a day. They need the energy to grow, which is why they sleep for most of the day, but in the hours when they are awake, German Shepherds tend to be very active.

Dogs that exercise a lot will also sleep more to recuperate the energy lost during the day. If there are many new things to explore, the dog will sleep for fewer hours during the day. Some four months later, German Shepherds will also take 15 to 20-minute naps during the day, and then they will wake up to play, eat, or use the bathroom.

Health and Care

Each time you take your dog to the vet, you should weigh and measure your German Shepherd to make sure that they are growing at the proper rate. If your dog is healthy, it should be growing quickly, and the veterinarian can confirm that everything looks good.

At the age of four months, you should get a third set of vaccines, including DHPP and rabies, to protect your dog against these diseases. This can be done through a veterinarian. Vaccines are important to complete on time to boost your dog's immune system and keep them as healthy and up-to-date as possible.

It is important to take your dog to the vet if you notice extreme changes in behavior, sleeping patterns, coughing or sneezing, runny noses or overly watery eyes, any form of weight loss, lack of appetite, heavy breathing, excessive urination, irritated gums, vomiting, or diarrhea. These can be signs that your dog is sick and needs medical care.

Bathing your German Shepherd too often can cause the natural oils that a dog needs to keep its skin protected to dry up, so it is important not to over-bathe your puppy. However, it is important to keep your dog's bed, bowls, and toys clean to avoid fleas or other insects that might negatively affect your pet.

As your four-month-old German Shepherd's coat is transitioning into an adult coat, it is important to brush the fur every day. This is to prevent excessive shedding, which can irritate your dog and create a mess inside the house. It is important to always be gentle with your dog and not brush him too roughly.

Feeding Your 4 Month Old German Shepherd

A German Shepherd is a big dog, and at the age of four months, it is still a puppy that is actively growing and will therefore require a large amount of food.

Four-month German Shepherds should be fed three times a day, and they should eat one to two cups of kibble at each feeding time. This kibble should be specifically meant for puppies of this age, as it will have the proper nutrients and ingredients for your puppy to grow into a healthy adult.

At the end of the fourth month, you can begin to feed your dog twice a day, but they should still be eating kibble meant for puppies until they reach six months of age and they are no longer growing as rapidly.

Treats are also a good addition to kibble, but you should not exceed three to five small treats per day. These treats should be exclusively for dogs, as feeding your German Shepherd adult food can cause many health issues.

It is important to monitor how much you are feeding your dog, as overeating can cause obesity and lead to severe health issues. Additionally, if you decide to use a raw diet rather than kibble, it is important to be mindful of the quality and nutrition of the food to keep your German Shepherd healthy and energized.

A four-month German Shepherd will be easy to train because the puppy's main goal will be to please their owner, and they are very intelligent and loyal dogs that will be eager to learn from their owner. One of the reasons why German Shepherds are such a popular breed is because of their trainability.

A German Shepherd's instinct is to protect, as the breed was originally bred to herd and protect sheep. This can lead to a puppy barking often as a means to protect its family, and this can be a misbehavior that the owner hopes to correct. Training can help reduce unnecessary barking in your German Shepherd puppy.

Another potential behavioral issue is using the bathroom inside the home, which is common at four months old. The owner must train their dog to go outside to use the bathroom, and patience is required for this process. The most efficient strategy for potty training is to be encouraging when the puppy correctly uses the bathroom outside and to avoid any anger when they have an accident, as this will only make training go slower.

German Shepherd puppies might also bite and nip people to try to get attention or play. It is important to avoid screaming when this happens and instead say “no” in a firm voice, which will communicate to the dog that they are misbehaving. They will understand that they should not repeat this behavior and will learn quickly.

While your German Shepherd is teething, it might bite furniture, which can cause damage. The best way to avoid this is to buy many chew toys to help your dog with the process of teething, as well as move any valuables out of the dog's reach. This behavior will reduce once the dog's adult teeth have all come in.

Socialization with people and other animals can help your German Shepherd behave better, and it is important to expose them to new situations to help them learn. They are very curious animals who will enjoy having new experiences and trying new things.

How Big is a 4 Month Old German Shepherd?

A German Shepherd is a medium to large-sized dog, and by the age of four months, the puppy will already be much larger than it was at birth. At four months, a male German Shepherd will have a shoulder height between 11 and 14 inches. A female German Shepherd will have a shoulder height between 10 and 12 inches.

How Much Should a 4 Month Old German Shepherd Weigh?

A male German Shepherd at four months old should weigh 35 to 40 pounds. A female should weigh 31 to 35 pounds. The dog should be rapidly growing, but it is important not to let them overeat because obesity can be a real health issue for your dog.

Measuring the weight of your dog regularly can help you keep track of its growth, and if there are any concerning patterns, you should discuss it with your veterinarian. At the age of four months, it is not unusual for your dog to grow up to two pounds in a single week, and it is a time of great change and growth.

How Much Should a 4-Month-Old German Shepherd Eat?

At the age of four months, your German Shepherd should eat three meals a day. These meals should consist of one to two cups of kibble. This means that the total amount of kibble eaten per day should be three to six.

You should base how much you feed your German Shepherd on their size, activity level, and how hungry they are. If you are unsure about how much to feed the puppy, you should consult your veterinarian for help.

Treats are also a good supplement to a German Shepherd's diet, but they should not exceed 10% of the total food you are feeding your dog each day. Treats can be used in moderation to train your young puppy and motivate them to partake in good behavior, or they can just be used as a snack throughout the day.
