Squishy faced dogs – Brachycephalic Airway Syndrome

We see a lot of dog breeds with squishy noses or short muzzles such as French Bulldogs, Pugs, Boston Terriers, Boxers and Bulldogs here in Richmond. These breeds of dogs often suffer from a condition called Brachycephalic Airway Syndrome.

What is Brachycephalic Airway Syndrome?

The word brachycephalic stems from the Greek roots brachy meaning ‘short’, and cephalic meaning ‘relating to the head’. Brachycephalic airway syndrome (BAS) is a set of abnormal physical and functional airway traits that affects short or snub-nosed breeds of dogs, causing a degree of obstruction to the breathing. Brachycephalic breeds of dog have been bred for a particular cosmetic appearance that can come with some compromises to the structure of their airways. Fortunately, most dogs do not suffer from all aspects of BAS, but you should be aware of which traits are possible in your pet.

Primary Conditions

There are several primary conformational traits present in brachycephalic pets that can impede airflow through the upper airways. These primary conditions include narrow nostrils, a long soft palate and a narrow windpipe. Although these traits are a common finding, they reduce normal airflow in the upper airways with serious consequences. With time, and without correction, these primary conditions may lead to secondary, irreversible disease, such as laryngeal collapse.

Stenotic Nares:

Stenotic nares are narrowed nostrils, which tend to collapse inwards during inhalation (breathing air inwards), resulting in difficulty breathing through the nose. This condition is found in 50 – 85% of dogs with BAS.

Elongated Soft Palate:

Because brachycephalic dogs have a relatively ‘squashed’ face, it can be difficult for all the soft tissues of the mouth and throat to fit in an anatomically acceptable way. As a result, the soft palate, which divides the back of the nose from the back of the mouth, can flap loosely in the throat creating snorting sounds. Excessive barking, exercise or panting may lead to inflammation and thickening of the soft palate that can irreversibly worsen over time. In humans the soft palate is the fleshy area at the back of the roof of the mouth. Approximately 90% of brachycephalic dogs will have an elongated soft palate.

Tracheal Stenosis, Hypoplastic Trachea:

The trachea is the ‘windpipe’, and can be very narrowed along certain sections, especially during inhalation. This is a congenital condition, with English Bulldogs more frequently affected. Brachycephalic breeds in general have a narrower trachea compared to other breeds.

Secondary Conditions

The secondary changes found in brachycephalic airway disease develop due to the resistance to airflow when the pet breathes inward. The pressure this places overtime leads to chronic problems. The larynx and supporting structures become weakened, and the below problems can occur:

  • Everted Laryngeal Saccules
  • Laryngeal Oedema
  • Collapsing Larynx
  • Collapsing Trachea

The above traits all contribute to upper respiratory obstructions in the brachycephalic dog, causing them to breathe and pant inefficiently. In dogs, panting is an important behaviour that helps cool the body. As they need to put in so much extra work to be able to get breathe, this can cause inflammation and swelling making it even harder to breathe. Sometimes leading to the emergency situation of respiratory distress and heat stroke – of which, brachycephalic-shaped dogs are at the highest risk.

How can we help dogs with Brachycephalic Airway Syndrome?

For all of our brachycephalic pets, we need to ensure that we are mindful about certain aspects of their lifestyle:

  • Minimise stress where possible.
  • Provide an environment that is of comfortable temperature, eg a cool environment in summer. Be extra careful during hot days so that your dog is not at risk of heat stroke. Provide plenty of water, good air flow in the room, shade, ice blocks, etc.
  • Allow for appropriate levels of exercise. That is, not too little to cause weight gain, yet not too much to cause excessive panting and excitement.
  • Ensure your pet is of ideal weight.
  • Be aware of the level of breathing noise that is ‘normal’ for your pet, and get in touch with your veterinarian if they worsen.

Brachycephalic Airway Surgeries

BAS is progressive if it is not prevented, corrected, or at least managed from an early age eg in puppies between 4 to 5 months of age. The two most common surgeries performed are rhinoplasty and palatoplasty.

Rhinoplasty – Nare Wedge Resection: 

This is a simple surgical procedure where the goal is to increase the diameter of the nostrils to address the stenotic nares and allow for better airflow to occur during breathing. A small triangular wedge shape is snipped away from the outside tissues of each nostril, and then small temporary stitches are placed to heal the wound. The cosmetic results are very good.

Palatoplasty – Soft Palate Resection:

This is another one best performed at a young age, which is when the soft palate tissues are hopefully minimally swollen and thickened, and other secondary airway changes have not established themselves too well. The excess length of soft palate is trimmed away during this surgery. Post-operatively, 85 – 90% of dogs exhibit improvement, although some may still have breathing noises or snore during naps.

What other problems can affect brachycephalic pets?

A large proportion of dogs with brachycephalic airway disease will also suffer gastrointestinal problems. The increased effort required to breathe in these patients leads to high negative pressure in the gastrointestinal tract as well as the airways. Brachycephalic pets are also prone to some congenital and developmental abnormalities that affect the oesophagus (food pipe), stomach and intestines. These conditions include:

  • Oesophageal deviation – Shifting of the foodpipe from its normal position in the chest
  • Hiatal hernia – The stomach slides forward into the chest with breathing
  • Pyloric Stenosis – Narrowing of the outflow track of the stomach

Patients with gastrointestinal involvement may show signs of:

  • Vomiting
  • Regurgitation of food
  • Difficulty swallowing or eating
  • Increased salivation/drooling

The gastrointestinal effects of brachycephalic disease may be managed with medical therapy, such as antacids and specialised diets. However often correcting the brachycephalic airway abnormalities can improve and even often resolve many of these gastrointestinal signs.

Further information

More specific management of BAS depends on the individual patient – their age, the severity, symptoms shown, duration, etc . The key to success is early intervention

Benefits of Pet Insurance

The story of “Twig” the wonder kid and how pet insurance meant she could get the best care and treatment!

IMG_5930
Twig was a six week old kitten when she was adopted by Dr Jo through a vet friend.

Dr Jo immediately feel in love with Twig (named after a David Bowie song line). Her front two legs were bowed, this is known as varus. Even though there was hope they would straighten as she grew, Twig had a consultation with Dr Guy Yates at CARE, an orthopedic specialist.

IMG_5525
By eight weeks of age when Twig was able to be insured with Petplan, her front legs had straightened out and the specialist surgeon was happy with her progress. The thought was to re-evaluate as she continued to grow with further x-rays or even a CT.

At the age of three months, the genetic wonder that is Twig developed yet another issue. She was seen to be lame on her left hind leg after a growth spurt so off again to Dr Guy she went for another assessment. More x-rays were taken and a diagnosis of a permanently luxated left patella (knee cap) was made. It was also discovered at that time that she also had a subluxated left hip and had mild hip dysplasia. A follow up CT was performed to assess all of her growth plates, but thankfully, these were all clear apart from her left hind leg.

Given the severity of her patella issue, it was decided that Twig would benefit from surgery sooner rather than later to try to ensure a functional knee for her as she continued to grow. So at the tender age of five months, she underwent specialist surgery with the wonderful Dr Guy.

The hardest part of the surgery was the minimum three weeks of confinement for Twig and being separated from her friend, eight month old Jellybean. A large cat enclosure was set up in the lounge room for Twig so that she could still be a part of the family but not be able to run free and compromise the surgery. Play dates were had with both Jelly and Dr Jo’s oldest (16y) feline fur kid Kutut so that Twig was never lonely.

After ten weeks, Twig had her post surgery check with Dr Guy and the great news is that she has healed beautifully! Even her left hip is improved since her knee is now functional and no more surgeries or anaethestics are needed. We wilkeep an eye on her hip over the coming months.

Twig is one very lucky kitty to have landed in Dr Jo’s cat heaven where her insurance has thankfully covered everything for her stifle and hip!

Surgery for intestinal blockage in cat

Odin Scheepers

Odin is a handsome Birman kitty who visited Swan Street Vet after he had been vomiting for a few days. On questioning the owners we found that Odin enjoys eating unusual objects like clothing, cushions and toys! Remember we are talking about a cat here, not a Labrador!

On physical examination he was found to have a very sore abdomen and his intestines were bunched together. Poor Odin had eaten something he shouldn’t have and this was causing a blockage in his intestines. This is known as a foreign body, causing a gastrointestinal obstruction.

Odin was placed on a drip and given pain relief before undergoing emergency surgery. It was found that he had eaten two lengths of wool, totaling one meter! Why? We suspect he wanted to knit himself a scarf.

During his surgery his whole abdomen was thoroughly examined. Both his stomach and intestines needed to be opened to remove the wool and allow his intestines to relax. Once the surgery was complete Odin’s recovery was continually monitored by the vets and nurses, ensuring he was comfortable. He recovered very well from his surgery and was able to go home the following day. He was a very lucky boy!

There are many different reasons why dogs and cats can vomit. A few causes include dietary intolerances, infections, parasites, foreign objects causing obstruction, as well as liver and kidney problems. In Odin’s case he was vomiting because he had eaten wool that was causing an obstruction in his intestines.

Other signs that could indicate a problem include, reduced appetite, weakness, diarrhoea, weight loss, or your pet generally not being themselves.

If you notice any of these signs please seek veterinarian attention immediately.

Odin is doing very well at home and has recovered completely!

It’s probably best not to let your cat play with wool or string after all!
