Fun Facts

  1. One of the most famous Prohibition aged Sealys was named Bootlegger.


Sealys are prone to allergies. Before adopting always request health screening from both parent pups. These pups are typically very healthy. Some issues you should be aware of include:

  • Retinal dysplasia: Both an inherited and a result of viral infections, retinal dysplasia is an abnormal growth of the retina in the eye.
  • Primary lens luxation: Here, the tiny fibers that hold the lens suspended in the eye begin to degrade. Eventually, the lens can fall out of place.
  • Deafness: Deafness can be hereditary or can happen through infection, trauma, or a degenerative cochlea.

While you always hope your pet will live a long and healthy life, it is always a good idea to invest in pet health insurance.

Keeping your dog’s mouth clean and problem free goes a long way to your pup’s overall health. Dental hygiene can be the cause or can be the byproduct of other serious health issues.

Visual inspections can be performed to keep track of the signs of potentially waning oral health. These signs can be anything from bad breath to abnormal chewing to loss of appetite.

Keeping ahead of these warning signs can pay dividends. A preventative approach can delay and stop many of the common dental problems from arising.

Oral health can be tackled in five basic steps:

  1. Brushing your dog’s teeth to prevent an undesirable buildup of plaque
  2. Feed your dog a diet where the high quality dog food has dental benefits
  3. Regularly give your dog dental toys and treats
  4. Use mouthwash, to help where brushing misses
  5. At the sign of any abnormalities, consult a vet. You can even do it virtually, from the convenience of your home.

Dogs are just like humans in that they can experience anxiety. The degree to which they are susceptible to anxiety and how they deal with anxiety is breed specific. Left unchecked, initial signs of anxiety could give way to an anxiety disorder. The symptoms of anxiety disorders can lead to a myriad of behavior issues.

Knowing the signs and symptoms will best equip you to keep ahead of it and to nip it in the bud at the earliest signs. There are options available to help with anxiety.

As with all pups, early socialization with humans and other pups is key. Early training is ideal for Sealys. Firm but fair and consistent training with lots of positive reinforcement is key. Sealys have been known to be food guarders. Possession aggression should never be allowed as it can go from simply growling to lunging and potentially more problematic quickly.

Proper training is essential to ensuring the safety of your dog and those around you.

Unless you’re living on a farm, or have the space, a yipping dog, or one that barks all day when you are gone could be an issue with the neighbors and/or landlord.

Barking is deep rooted in dogs and manifests itself in many ways and for a variety of reasons.

Just like any habit or instinct, there are effective ways you can train this issue away.
