Coughing cats

At first Gus’s carer thought he had hair balls. So did the friends she asked. He gagged and convulsed and brought up froth. She gave him some laxative paste.

Everything in the litter tray seemed normal and for a while Gus seemed OK.

When she rushed off to work he was curled up on the lounge in the sun room as usual.

But the gagging started up again, especially at night. She noticed that he wasn’t eating all his dinner and sometimes he stopped in the middle of the gagging and breathed heavily.

One night he crept on to the end of the bed and wheezed and gasped for breath until she was sure he was choking to death.

Next morning she rushed him into us. We X-rayed his chest and found a very hazy lung and signs of chronic bronchitis.

We took samples from Gus’s lungs and found he had pneumonia. Gus had developed an airway and lung infection on top of the chronic bronchitis.

Cats get asthma and bronchitis, just like humans do. For some it is worse when there are lots of pollens blowing about, for others being cooped up inside with the stagnant air and dust mites in winter set the wheezing and coughing off.

His carer remembered that he had always had a bit of a wheeze, especially in spring and early summer. She hadn’t thought much of it.

It is very easy to confuse coughing with vomiting or regurgitation. Usually food or bile will come up at some stage with vomiting. Vomiting cats often lose their appetite or have diarrhoea as well. Coughing cats don’t go off their food unless they develop an infection as well.

Some asthmatic cats have life threatening breathing difficulties if they are not treated adequately. If you notice your cat coughing, gagging, breathing with difficulty, especially with the mouth open and the neck extended, contact your vet.

Gus is back to his irascible self after a long course of antibiotics. He’s getting used to a puffer and spacer, and quite likes all the attention we give him.

Heartworm

Heartworm live in the heart and major blood vessels of infected dogs.

How do dogs get heartworm?

Female heartworm produce millions of young, or microfilaria, which live in the bloodstream. Mosquitoes ingest microfilariae when they bite an infected dog.

The microfilariæ develop further in the mosquito. When the mosquito bites another dog it injects larval heartworm. These larvae migrate to the heart and adjacent vessels over a few months, and grow to adult heartworm.

Usually dogs do not show outward signs of infection for a few years.

How do heartworm affect dogs?

Adult worms:

Adult worms clog the heart and the major blood vessels leading from the heart. They stop the heart valves from closing and reduce blood supply to the rest of the body.

The most obvious signs are: a soft, dry, chronic cough, shortness of breath, loss of stamina, and weakness, especially after exercise. Heavily infected dogs may faint.

Sometimes we hear heart murmurs or abnormal lung sounds with a stethoscope. In advanced cases the abdomen and legs swell with fluid accumulation. Weight loss, poor condition, and anaemia develop with a chronic infection.

Severely infected dogs may die suddenly during exercise or excitement.

Microfilariæ (Young worms):

Microfilariæ circulate throughout the body but prefer small blood vessels. Because they are as wide as the vessels, they may block blood flow to vital organs such as the lungs, liver and kidney.

How do we prevent heartworm?

Annual injections of Proheart SR-12, or monthly tablets such as Heartgard or Proheart, or spot-ons such as Advocate or Revolution all kill larval heartworm before they reach the heart.

Before starting a preventative we run a blood test in the surgery to check for any existing infection.

If we detect an existing heartworm infection an effective treatment is available. Before admitting an infected dog for treatment we screen for damage to the liver, kidneys, heart and lungs to reduce the chance of complications.

Heart care for dogs

Dogs suffer from heart failure, just like humans. If dog owners recognise the warning signs of heart failure they can seek help earlier and enjoy a healthy, happy pet for longer.

Research shows that most dog owners are not aware of the risk of heart failure in older dogs, even though 1 in 10 dogs presented to vets suffer from heart disease.

Boehringer Ingelheim has launched a Heart Failure Awareness Program to raise owners’ awareness of the signs of heart disease in dogs. The company wants to reduce the numbers of dogs suffering unnecessarily from this life threatening condition.

The Heart Failure Awareness Program is aimed at dog owners because they are most likely to notice changes in their dog’s health and behaviour.

Early signs of heart failure, like loss of appetite, are subtle and often overlooked.

The common signs of congestive heart failure include:

  • Coughing, especially at night
  • Poor appetite
  • Reluctance to exercise and tiring quickly on walks
  • Laboured or fast breathing
  • Fainting – often associated with exercise
  • Weight loss
  • Enlarged abdomen
  • Weakness

If your dog is aged seven or more and showing one or more of the above signs visit a vet without delay.

Effective treatment of heart failure is available and when started early greatly improves affected dogs’ quality of life.

If owners recognise the signs of heart failure early and seek veterinary advice before the heart deteriorates markedly, treatment has the greatest benefit.

Research has shown effective treatment allows dogs with heart failure to enjoy many healthy, good quality years of life.

And that’s something all dog owners want.

Collapsing tracheas

Collapsing tracheas are common in small dogs like Chihuahuas, Pomeranians, Shih Tzus, Lhasa Apsos, Toy Poodles, and Yorkshire Terriers.

The trachea, also known as the windpipe, connects the throat to the lungs. The normal trachea is tubular and maintains its shape with a series of “C” shaped rings made of cartilage.

When a dog with a collapsing trachea breathes in, the cartilage rings flatten from top to the bottom. This makes it difficult for air to enter the lungs and causes a chronic, honking cough.

In affected dogs the cartilage rings lose their stiffness and cannot retain their circular shape.

Coughing is often worse in the daytime. The cough is exacerbated by excitement, drinking water, eating, or pressure on the trachea, particularly from a leash.

We suspect a collapsed trachea in a small dog with a persistent dry and/or honking cough. If light pressure over the trachea causes a cough we recommend a chest X ray to rule out other heart, lung and airway problems. These other conditions are common in small dogs and they often suffer from several of them at a time.

Endoscopy allows us to watch the inside of the trachea during inspiration and expiration for signs of collapse.

We treat a dog with collapsing trachea with drugs to open up and reduce inflammation of the airways.

Antibiotics control infections of collapsed airways, which are common.

Weight loss reduces pressure on the airways in obese dogs. A low fat diet and mild exercise helps them shed the extra kilos.

Avoid exacerbating the cough with excitement and vigorous exercise.

Because medical therapy only treats the cough and does not correct the problem, affected dogs will always have a bit of a cough. Our aim is to minimize the cough, and make them more comfortable and active.
