How to Identify a Seal Boston Terrier

Have you ever wanted to know if a seal Boston Terrier is real? The seal has become a catch-all word for Boston Terriers of all colors, perplexing some pet owners. The seal is a tricky color to identify for individuals unfamiliar with the Boston Terrier breed.

Those already familiar with them may also be confused. The color of the coat is neither red, brown, liver, nor chocolate. Even though it appears dark and almost devoid of color, it reveals its color when exposed to direct sunshine. 

When the light catches the coat in just the right way, red undertones peek through, giving it the appearance of a wet sea lion. So, the simplest way to tell if a Boston Terrier is a seal is to hold it up to the light and check the color.

Seal Boston Terriers Training Requirements

Since Seal Boston Terriers are intelligent puppies, you should start training them while they are still young. When training your Seal Boston Terrier, expose and introduce them to other pets and be consistent with your training schedule.

The first step in your seal Boston Terrier’s training is to housebreak (or house-train) them. It will build the groundwork for your dog’s good behavior for the rest of its life. There are five main areas in which to train your dog at home:

  • Potty training: Choosing a toileting area for your dog can help you create a routine. Furthermore, the schedule informs your Seal Boston Terrier that there are periods for everything, including eating, playing, walking, napping, and pooping. 
  • Crate training: It aids in toilet training, adapting your dog to traveling in a carrier, and serving as an open sanctuary where your dog can feel comfortable and retire. 
  • Leash training: Every dog should be able to walk on a leash at some point. It is critical to use a collar and leash appropriate for your seal Boston Terrier’s strength, size, and age, as this makes a significant impact.
  • Socialization: It entails exposing your seal Boston Terrier dog to new people, animals, and environments to train it to be comfortable around them. Throughout your terrier’s life, you should continue to expose it to new people and environments.
  • Basic commands: Your seal Boston Terrier must learn to obey and follow your commands. It would be best to start with the basics, such as sit down, stay, come, and leave it. Just start with one instruction at a time and work your way up.

Seal Boston Terriers Health Issues

Seal Boston Terriers can live up to 15 years if they are well cared for. However, like most other dogs in this breed, Seal Boston Terriers are susceptible to some health conditions that you should be aware of. Below are the most common ones:

Heart Disease

Heart disease is the primary cause of mortality in aged Boston Terriers. The weakening of a valve is the most common cause of heart disease in dogs. A heart valve gradually deforms to the point where it no longer closes tightly.

The heart is then strained as blood flows back around the valve. Heart valve disease (also known as mitral valve disease) causes a heart murmur in pets.

Seal Terriers may suffer from congenital heart problems. Unfortunately, this condition can take long before showing up. While most heart issues are genetic, some can be caused by overfeeding your dog. That’s one of many reasons why you should manage your puppy’s diet to control her weight. 


This is an eye condition that occurs when the eyelid of a Seal Terrier rolls inward. Other eye infections can be caused by ulcers on the cornea or dry eyes, which can be corrected by surgery or by visiting a vet for regular check-ups.

Hair loss

Premature baldness affects both male and female seal Boston Terriers. The hair eventually falls out and does not regrow. The loss of hair does not cause itching, though the skin can become dry at times. Typically, the neck, chest, belly, and insides of the legs are affected. 

Ensure you run tests to rule out any treatable conditions that cause hair loss, such as thyroid hormone deficiency. If your pet has genuine pattern baldness, your vet may be able to aid you with supplements or hormones, though there is no cure.

Hip Dysplasia

This occurs when the joint and ball socket of your Seal Terrier doesn’t fit properly into the hip socket. In turn, the two bones start rubbing against each other and eventually deform the hips. Check out these signs to know if a dog is suffering from this problem:

  • Your puppy is having difficulties climbing the stairs
  • Your puppy doesn’t want to run or jump
  • Your puppy is limping while walking

Spinal Deformities

Boston Terriers, especially seal Boston Terriers, are more prone than other dogs to be born with spine abnormalities (hemivertebrae), which can cause injury to the spinal cord, instability, and impairment.

Professionals recommend taking X-rays while your dog is young to be sure you catch any abnormalities early. Signs and symptoms may worsen with age, weight, and activity.

Suppose your Seal Boston Terrier develops signs of back difficulties later in life; your veterinarian will rule out other possibilities like a sprain or arthritis and may recommend medication, acupressure, or rehabilitation.

Where To Buy Seal Boston Terriers

If you want healthy Seal Terriers, avoid buying from pet brokers or puppy mills. Instead, select a reliable breeder such as the American Kennel Club. The club can give you health certificates to ensure you’re buying a healthy dog. The cost ranges from $600-$1,200.
