Begins to Mature

You’ll know your Bull Terrier reaches adulthood when it starts manifesting signs of maturity physically, sexually and mentally. In the next section, we will discuss the different aspects of maturity in a dog.

Physical Maturity

Physical maturity in dogs means they reach their full-size potential. A Bull Terrier physically matures between 20 to 24 months when it finally reaches its full height and weight. However, even though your Bull Terrier reaches its full size doesn’t mean it automatically stops its puppy-like behavior.

It’s just important to determine your Bull Terrier physically matures so you can give him appropriate dog food that meets its nutrient requirements.

Mental Maturity

The mental maturity of a Bull Terrier varies. On average, expect your Bull Terrier to mentally mature when it reaches one to four years old. Mental maturity brings a change in behavior such as halting its puppy-like behaviors.

A mentally matured dog is characterized by:

  • better at listening 
  • more obedient
  • doesn’t easily get distracted
  • calmer
  • more settled demeanor

When your Bull Terrier reaches its adult stage, it fully settles into its new role as an adult.

Sexual Maturity

A dog’s sexual maturity comes first before it reaches mental and physical maturity. Your Bull Terrier sexually matures as early as six months and as late as nine months. Expect your dog to exhibit behavioral changes due to changes in hormones.

Typically, a female dog goes into heat twice a year. Observable changes include swelling of the vulva and red vaginal discharge in a span of seven to 10 days. 

On the other hand, a sexually mature male Bull Terrier exhibits behavioral changes like marking its territory. You’d also notice him roaming around more often. At this stage, you need to decide whether to spay/neuter your dog or not.

It’s best to consult your vet for the right time of neutering or spaying to avoid any health problems caused by too early neutering or spaying such as orthopedic problems.

Less Destructive Behavior

According to Dr. Melissa Bain, a professor of clinical animal behavior from the UC Davis School of Veterinary Medicine says that the destructive behavior of puppies lessens as they mature.

It starts when they grow their puppy teeth changes to adult teeth. You’ll start observing that their destructive behavior, such as chewing, slowly ceases as early as five months.

Less Playful

Bull Terriers are remarkably energetic dogs especially when they’re still puppies. Although they are still full of energy and very playful, you’ll notice that the energy levels aren’t the same compared to when they’re still puppies. Instead, you’ll notice your dog becomes more interested in exploring his surroundings.

Responsive to Training

Adults are easier to train than puppies. Usually, puppies don’t really pay attention nor listen when you tell them to do something. Meanwhile, adult dogs aren’t easily distracted compared to puppies.

They tend to pay more attention and concentrate on their owner’s supervision and directives. This is contrary to the misconception that adult dogs are harder to train. 

Nonetheless, it’s recommended to train your dog at a young age because you can prevent him from acquiring bad behaviors. It’s easier to teach your dog to learn something than to teach him to unlearn something. However, it’s never too late to correct your dog’s behavior even when it’s already adult.
