Birth – 2 Weeks

From birth until the age of two weeks, your Pitbull puppy is considered to be in the neonatal stage of life.

This is the period where they depend entirely on the mother for defecation, food, and warmth. Their bodies cannot generate heat, so the mother provides them with the warmth that they need.

During this stage, your puppy will be eating or sleeping most of the time. At the end of two weeks, their eyes begin to open and they should have doubled their birth weight.

3 Weeks – 12 Weeks

At three weeks old, your puppy’s ears open and they can now hear the sound in their environment. their milk teeth also begin to come out.

At this stage, your puppy will grow rapidly, both emotionally and physically and they will learn acceptable behavior from their mother and littermates.

You can start socializing your puppy but ensure that they are vaccinated.

At seven weeks, you can introduce solid foods to your puppy and they should be learning how to wag their tail, vocalize, and run. Your puppy is ready to move to their new home by the age of eight weeks.

4 Months – 9 Months

You will notice that your Pitbull’s soft coat is being replaced by a denser and harsher adult coat. They will start teething at this age, hence proper teething toys should be provided to ward them off furniture and shoes.

Socialization begins at home, therefore you should expose them to daily sounds and sights such as vacuum cleaners, hairdryers, other pets, and children.

You can take them to obedience classes so that they can receive professional training as they will start being stubborn and challenging you.

At this age, females may experience their first heat while males start to lift their leg to mark, which makes it the right time to sterilize them to avoid unwanted litter or aggressive behavior.

How Big Do Pitbulls Get?

There are a few ways that you can use to determine how big your Pitbull will get.

First, if you got your Pitbull from a breeder, ask them about the puppy’s estimated adult size. Based on the parent’s information and previous litters, your breeder should be able to give you an estimate of the adult size of your Pitbull.

If you can visit the breeder and look at your puppy’s parents, you will have a clear picture of what your Pitbull will look like when fully grown.

Secondly, you can check your puppy’s paws. If they appear to be oversized next to their body and legs, then they are still growing and filling out so that their body is proportional.

Checking the Pitbull size chart will also give you an idea of your puppy’s final weight as an adult.

If you cannot get the parents’ information because you adopted your Pitbull from a rescue center, then do a DNA test and use the results to estimate how big they will get.

An adult Pitbull stands at a height of between 17 and 21 inches with a weight of between 30 and 60 pounds.

Pitbull Genetics and Common Health Problems

Pitbull are susceptible to several health problems and the most common are;

Hip Dysplasi – is a condition that causes the dog to have difficulty moving freely and develop pain. Pitbull suffering from this condition have a shallow hip socket and an improper fit of the femur ball.

When the femur ball and the socket do not fit together the hip cartilage wears off causing pain. This condition leads to arthritis in older Pitbull.

A kneecap dislocation or luxating patella is a condition that causes the kneecap to slip off from the normal position. When this happens the dog’s knee cannot be able to extend properly and gets bent.

Sometimes the kneecap moves back to its position when the dog takes some steps but in serious cases, surgery is required to improve the life of the dog.

Degenerative myelopathy – Pitbull is commonly diagnosed with this condition. This health problem causes a progressive loss of the functions of the nerve because of an inherited mutation in the SOD1 gene.

This disease manifests in older Pitbull as loss of coordination and muscle atrophy and eventually prevents the dog from walking.

Congenital heart defects are heart disease and Pitbull is susceptible to it. It happens when there is too much pressure on the left ventricle and causes shortness of breath or chest pains due to the narrowing size.

Your vet can diagnose your Pitbull by listening to your pet’s heart.
