COULD YOUR POOCH BE A LIFESAVER? NEW RESEARCH PUTS DOG BLOOD DONORS IN THE SPOTLIGHT
Most of us know a blood donation can save a human life, but fewer people realise that dog blood donors play the very same role for our furry family members.
Now a new study from the United States could make every one of those precious donations go further.
Researchers at Washington State University's College of Veterinary Medicine have found a way to store a vital blood product for weeks rather than days, as reported this week.
Why Dog Blood Donors Matter
Just like people, dogs can suffer serious bleeding after accidents, during surgery or because of illnesses that affect how their blood clots.
In those moments, a transfusion can be the difference between a dog going home and a heartbreaking goodbye.
One of the most important products in these emergencies is platelets, the tiny cells that help blood form clots and stop bleeding.
The trouble is that platelets are usually stored at room temperature and only last a few days.
That makes them hard for vet hospitals to keep on hand when an emergency comes through the door.
The New Research
The study, published in the Journal of Veterinary Internal Medicine, looked at platelets that had been processed and kept in the fridge instead.
The team found canine platelets could be refrigerated and stored for up to three weeks while still working effectively.
The research involved 24 dogs treated at the university's veterinary teaching hospital.
In 70 per cent of cases, the cold-stored platelets improved bleeding or helped prevent bleeding complications.
No transfusion reactions were recorded, and it is described as the first clinical evidence that cold-stored platelets work in dogs.
Refrigerated platelets are also less prone to harmful bacterial growth, do not need constant agitation and are easier to ship.
Lead researcher Dr Jillian Haines, who runs the hospital's blood bank, said that when these products are needed, "it is the only option".
The team now plans to study the best doses and whether the platelets stay effective for even longer than three weeks.
The Australian Picture
Here at home, vet hospitals rely on generous owners whose dogs roll up their sleeves, so to speak.
Earlier this year, emergency vets in Melbourne warned that pet blood supplies were running low, as Better Homes and Gardens reported.
Dr Luke Johnston from Greencross Vet Hospital at the University of Melbourne said at the time that "a single donation can save a life".
Advances like longer storage could help make the most of every donation that kind-hearted dogs and their owners give.
Could Your Dog Become One Of Our Dog Blood Donors?
Eligibility rules vary between clinics, so it is always worth checking with your local emergency or referral hospital.
As an example, the University of Sydney's canine blood bank asks for dogs that are fit and healthy, aged one to eight, and weigh more than 20kg.
Donor dogs must be up to date with vaccinations and with heartworm, worm, flea and tick prevention.
They also need a good temperament, must never have travelled outside Australia, never been pregnant and never received a transfusion.
The process starts with a meet and greet, including screening blood tests and a temperament check.
On donation day, the collection itself takes around 10 to 15 minutes, and most dogs head home the same afternoon.
Eligible dogs can donate every three months.
Sydney's program even rewards its canine heroes with perks, including a $100 clinic credit, a vet check, lab tests and flea and tick prevention.
Owners also receive a message when their dog's donation has helped save another animal.
A Few Things To Keep In Mind
Vets generally consider donation very low risk for eligible dogs, though some may feel a little tired or have minor bruising afterwards.
If your dog is anxious at the vet, talk to the team first, as temperament is part of the screening.
If you are unsure, your regular vet is the best person to ask about whether your dog could help.
It is a lovely way for your best friend to give back, and another family may be very grateful you did.
