Ethylene glycol – The deadly substance in antifreeze

Dogs 22 - Ethylene glycol

Antifreeze is very common in our homes during the winter months whether it is being used to prevent water from freezing inside our household pipes or to de-ice our cars in the morning. This substance is also present in most motor vehicle antifreezes and it is also found in some screen washers.

The problem with antifreeze is one of its components, a substance called ethylene glycol. This substance is extremely toxic for pets, particularly cats, and even if ingested in small amounts it can rapidly lead to kidney failure and death.

Antifreeze poisoning is one of the most common types of poisoning in small animals and statistics show that 90% of cats that swallow antifreeze will die.

Usually cats will come across antifreeze when it leaks from car engines into the ground. Cats that spend a significant amount of time outdoors will often hide under cars and sometimes they might even crawl into the car’s engine in search of warmth and shelter. A few drops of antifreeze will quickly form a small puddle which is usually the only liquid around that is not frozen. Cats, dogs and even wild animals might find it and drink it.

Symptoms of ethylene glycol poisoning can appear up to 12 hours after ingestion. Pets will often display difficulties walking, appearing wobbly, almost like if they were drunk and many will become more vocal. As time goes by the symptoms can evolve to depression, lethargy, increased thirst and urination, vomiting and seizures (fits). After 24 hours it is very likely for your pet to be suffering from acute renal failure and their chances for recovery are very poor.

If you recognise any of these symptoms or if you suspect your pet may have ingested antifreeze please do not hesitate and contact your vet immediately. Your pet’s chances of recovering depend on how soon he or she receives treatment!

We recommend all owners to be very careful when using and disposing of used antifreeze. Please make sure you always keep it away from your pets and immediately clean any spills that may happen by accident.

Equine grass sickness – A difficult and devastating disease

Equine-grass-sickness

Equine grass sickness, also known as equine dysautonomia, is a debilitating and often fatal disease that causes a marked reduction of the gastrointestinal motility due to damage to the autonomic nervous system.

This condition was first recognized in 1909 in Scotland and it is seen throughout northern Europe and also South America. Great Britain has the highest incidence of grass sickness in the world and it affects horses, ponies and donkeys.

Grass sickness can occur at any age and at any time of the year but it has a seasonal pattern, with most cases being seen during spring time.

The cause of this disease is unknown but apart from grazing, different risk factors such as certain types of wormers have been identified. However, not worming a horse can have very serious consequences as well, which means that owners should not decrease their use of wormers. Many potential causes have been examined over the years and the type of damage to the nervous system suggests that a toxic substance is likely to be involved.

Grass sickness occurs in three main forms: acute, subacute and chronic form. The clinical signs depend on the level of gastrointestinal dysfunction and severity of neuronal damage.

In acute grass sickness the symptoms appear suddenly and horses show severe colic, difficulty in swallowing, salivation, muscle tremors, droopy eyelids and sweating. Subacute cases show these same symptoms but they are less severe.

Both forms are fatal and affected horses are often put down once the diagnosis is made, in order to avoid unnecessary pain and suffering.

In the chronic form of grass sickness the symptoms develop more slowly. Horses lose weight and there are changes in their abdominal silhouette. In subacute and chronic cases their faeces may become dry, firm and present a black coat and mucus on them.

The prognosis of the chronic form is poor and approximately 45% of the horses will survive with treatment. Treatment is usually considered in mild chronic cases and if the horse is eating and not in too much in pain.

Since the cause of the disease is still unknown it is very difficult to take preventive measures. Stabling the animals during spring and early summer can reduce the likelihood of disease.

There is still a lot of research being done to find the cause of this condition, which would allow preventing it and treating it in a more effective way. The most recent theory being researched is the possible involvement of a soil-associated bacterium, Clostridium botulinum.

Pets and Ebola – What do we know so far?

Dogs 20 - Pets and Ebola What do we know so far
Ebola has been a recurrent topic on the news lately and recent events involving companion animals that were in close contact with Ebola patients have raised many questions among veterinary surgeons and pet owners.

The first person to contract Ebola outside Africa was a Spanish nursing assistant called Teresa Romero Ramos. Teresa became sick after she helped treat an Ebola-stricken Spanish missionary and health Spanish authorities decided to euthanize her dog as a precaution. Animal activists and the nurse’s husband went on a campaign to save the family dog, which was sadly unsuccessful. The decision of ending this dog’s life sparked international outrage and started a worldwide debate on whether pets are actually capable of spreading Ebola and how authorities should proceed with pets that may have been exposed to the virus.

According to the World Health Organization Ebola is a viral illness of which the initial symptoms include sudden a sore throat, fever, weakness and muscle pain. As the disease progresses patients may present vomiting, diarrhoea and sometimes both internal and external bleeding. The disease is spread through direct contact with infected blood, bodily fluids or organs of infected peopleor indirectly through contact with contaminated environments and objects. Humans can also be infected through handling or consuming infected animals, including chimpanzees, fruit bats, porcupines and forest antelope. Symptomatic individuals should avoid contact with people and animals.

According to the AVMA (American Veterinary Medical Foundation) and the Centers for Disease Control and Prevention there have been no reported cases of dogs or cats becoming sick with Ebola, even in Africa where the virus is present. A few studies have shown that dogs can contract asymptomatic Ebola, meaning they are infected but do not suffer any symptoms, as a result of eating infected animals. It is not yet known whether pets can spread the virus to humans or to other animals but there has not been a single case of Ebola being transmitted from a dog or a cat to a person.

In another recent Ebola case, a nurse called Nina Pham was also diagnosed with the deadly virus after treating an Ebola patient. Her dog Bentley was quarantined for 21 days, the maximum incubation period for Ebola in the human body, and after this period of time and several Ebola tests that came back negative the dog was released and reunited with its owner.

After working with vets, public health agencies and experts the AVMA has recently issued protocols that can be used by vets and other health officials to guide their decisions on the handling and care of pets that may have been exposed to Ebola.

Caring for an older dog

Dogs 18 - Caring for an older dog
As our beloved dogs get into their golden years, they go through several physical and behaviour changes.

Age alone does not define a dog as being old or geriatric as aging is a process influenced by genetics and lifestyle. A dog’s size has an enormous influence in its rate of ageing. In general, when considering small and medium size breeds, dogs are considered old (senior) between 11 and 12 years and are considered geriatric when they are more than 15 years old. Large and giant breeds are considered old by the age of 7 to 10 years and a giant breed dog would be considered geriatric at 11 to 12 years.

As dogs get older they will become less active, sleep more and interact less with their surrounding environment. As a result they often put on weight.Owners may also notice their pet shows some degree of sight and hearing loss.

Their appearance changes as well as their haircoat loses shine, their skin becomes less elastic and white hairs may start to appear.

These changes will occur gradually over time and owners should be suspicious if they notice significant changes over weeks to a few months, particularly if one area is affected significantly more than others. This could suggest that there is disease involved instead of the normal ageing process. Older dogs showing sudden weight loss, marked behavioural changes, increased water intake or reduction in activity should be seen by a vet as soon as possible.

Older dogs are more prone to disease such as arthritis, a chronic and painful condition that limits their movements; dental disease; renal problems and they often present a reduced cognitive function. Some dogs may present gradual weight loss due to poor digestion.

There is much owners can do to keep their senior dog comfortable, happy and healthy. Provide a soft, warm, comfortable bed and make sure food, water and resting spots are easily accessible. Raising food bowls off the ground will bring relief to dogs with stiff and aching joints as they won’t be forced to reach down to the floor when feeding.

Try to keep a daily routine for meals, walks and bedtimes. If possible, keep your dog’s bed, food and water bowls in the same place over time.

Grooming will be necessary to keep their hair coat in good condition and it is recommended to pay special attention to their nails. The nails of less active dogs can easily become too long, curl around and grow into their pads.

It is very important for owners to control their dog’s weight and have an adequate exercise plan. This will not only prevent stiffness and loss of muscle mass but it will also alleviate arthritis symptoms. Older dogs still need to exercise, they just need to do it on a slower pace, without pushing their limits. It is best if their walks are shorter and frequent (two to three times a day).

Keep an eye on any lumps or growths. These are typical of older dogs and although some may be nothing to worry about, unfortunately, others may be cancerous.

Senior dogs should go to the vet twice a year. Regular health checks are very important to pick up on any problems as early as possible and are also a great opportunity to get some good advice from your vet regarding your dog’s diet, exercise and general health.
