Sniffing Out Trouble

Posted on by

Dogs evolved as dogs precisely because of their relationship with humans. Man made dog and dog helped man.

Although the “jobs” that dogs undertake have changed radically in recent years, man and dog are still as thick as thieves and greater understanding of the science behind the relationship has enabled us to communicate and fathom dogs in a way that was undreamed of.

Anecdotal accounts of dogs being able to detect malignant tumours in humans led to dogs being trained to detect all sorts of volatile compounds that cause illness in man.

Now a study is underway in which six dogs are being trained to see if they can detect the SARS-COV-2 virus that causes COVID 19. The charity Medical Detection Dogs are working in partnership with the London School of Hygiene and Tropical Medicine and Durham University, with the aim that dogs could help to provide a rapid, non-invasive diagnosis, perhaps as soon as in 6 weeks.

MDD has already trained dogs to detect various cancers, Parkinson’s disease, bacterial infections and malaria.  Dogs are also able to detect subtle changes in skin temperature, so could potentially indicate if someone has a fever.

Trained dogs could be deployed to identify incoming infected travellers or be deployed in other public spaces to help with tracking and tracing infection as the lockdown is eased.

Pariah!

Indian pariah dog It is understandable in the current situation that research is published quickly and, of necessity, before peer review. Creditably, it is also often made available via Creative Commons licensing.

One such paper has been picked up by various media today suggesting that feral dogs rather than pangolins could have been a vector for the SARS-COV-2 virus.

Approximately 80% of the world’s dogs are feral, living alongside but not formally with, humans with varying degrees of tolerance on the part of the latter. One such group of dogs is a landrace dog on the Indian sub-continent. Taking their name from the Pariah tribe of Madras, a derivation of the Anglo-Indian word pye or paë and the Hindi pāhī meaning ‘outsider’, the term has become synonymous with all outcasts particularly those who are ostracised. Just as the very word “dog” is used as an insult, so the poor pariahs.

Feral dogs can and do transmit zoonotic diseases, notably rabies, but academics have already poured scorn on the suggestion that they have been responsible for humans contracting COVID-19.

The consensus appears to be that conclusion have been drawn from weak and erroneous evidence based on the suggestion that feral dogs ate infected bats and were them presumably eaten by humans as it has already been proven that dogs do not become symptomatic even in the rare event that they have become infected and that they do to transmit the virus easily.

As Professor James Wood, Head of Department of Veterinary Medicine and researcher in infection dynamics and control of diseases at the University of Cambridge, said:

“I find it difficult to understand how the author has been able to conclude anything from this study, or to hypothesise much, let alone that the virus causing COVID19 may have evolved through dogs.  There is far too much inference and far too little direct data.  I do not see anything in this paper to support this supposition and am concerned that this paper has been published in this journal.  I do not believe that any dog owners should be concerned as a result of this work.”

10 Ways To Survive Lockdown

Posted on by

Lockdown This is a difficult and unprecedented time for everyone in the world. There are no blueprints, no historical precedents on this scale to help us. Whilst we struggle to come to terms with a global pandemic, it is impossible to explain to our dogs why their world has suddenly shrunk and changed beyond all recognition.

There are some things that we can do to help them adjust and to make our lives a little less stressful whilst abiding by government advice and obligations and remaining safe.

1 Stimulation is as important for dogs as exercise. Find novel ways to keep your dog’s mind occupied, especially if exercise is limited

2 Now is the time to start or improve training. 5-15 minutes per day of non-aversive, positive training will work wonders

3 Use a lead and a long line when your dog is in public. Even if your recall is brilliant, that doesn’t apply to other dogs and it is imperative that you do not get into a situation that would make it impossible to keep at least six feet away from other people

4 Maintain a routine. Predictability helps dogs to feel secure even if it is different to your normal routine

5 Keep toys limited to two different types and swap them over periodically so that your dog does not become bored

6 Make sure that your dog has a safe, quiet place and can choose to go there, especially if your house is fuller and noisier than normal

7 Limit and control access that children have to your dog so that extra time at home does not mean extra pressure and stress for your dog

8 Take extra care to keep your dog safe from household poisons, toxic garden plants and dangerous food

9 If you have new puppy, find inventive ways to continue socialisation: use sound tapes, wear a variety of different clothes, create lots of different surfaces to walk on etc

10 Keep it fun: keep it safe.

Worried about whether your dog or cat could catch COVID-19?

There have been reports in the press that two dogs and one cat have tested positive for COVID-19. Companion animals act as fomites – a surface on which COVID-19 can settle and be transferred via direct contact. Current advice is that following the correct hand washing technique should help to protect you and your animals from infection.

A new study published by the Chinese Academy of Agricultural Sciences has found that dogs, pigs, chickens and ducks transmit the virus poorly, but that ferrets and cats transmit it much more effectively. The cats in the study passed the virus to other cats in close proximity through aerosol transmission.

Ferret and cats owners in particular should therefore be very careful to limit close contact and observe the recommended hygiene procedures.
