Computer games could slow mental deterioration in dogs
Playing computer games might be the perfect 'brain training' for old dogs.

Researchers train elderly pets to play 'sudoku'

Computer games for dogs could help to slow down mental deterioration, a new study has found.

The research was led by cognitive biologists from Vetmeduni Vienna, who propose computer interaction as a practical alternative to physical training. In the study, elderly dogs responded positively to interactive touchscreen games, including 'dog suduko'.

Researchers say that simple, mental computer tasks, followed by a reward, could replace physically demanding training and still keep animals mentally fit. They now aim to take 'dog sudoku' out of the laboratory and into people’s living rooms.

“The positive feeling created by solving a mental challenge is comparable to the feeling that older people have when they learn something new, doing something they enjoy,” explains senior author Ludwig Huber. “Regular brain training shakes not only us but also dogs out of their apathy in old age, increasing motivation and engagement and thus maximising learning opportunities.”

Puppies are typically socialised and challenged using an array of training methods. But as dogs get older, we increasingly - and unconsciously - reduce the level of regular training and challenges.

First author Lisa Wallis said that by reducing the level of training, we actually restrict opportunities to create positive mental experiences for our dogs:

“As is the case with people, dopamine production in dogs also falls in old age, leading to memory decline and motivational drive. But this natural mental deterioration can be countered with the specific training of cognitive skills,” she said.

The training works by using computer-based brain-teasers. While it took some time preparing the dogs for the games, they soon turned into avid gamers once they got the hang of it.

“Touchscreen interaction is usually analysed in young dogs. But we could show that old dogs also respond positively to this cognitive training method,” says senior author Ludwig Huber. “Above all, the prospect of a reward is an important factor to motivate the animals to do something new or challenging.”

Greyhound Board announces change to vaccination guidance

News Story 1
 The Greyhound Board of Great Britain has published new vaccination guidance, with all greyhounds registered from 1 January, 2027 required to have the L4 leptospirosis vaccination, rather than L2.

The change comes in response to the reduced availability of the 'L2' Leptospirosis vaccine across the UK, and aims to support best biosecurity practice across the racing greyhound population.

GBGB veterinary director Simon Gower, said "While rare, Leptospirosis is a serious infectious disease that can affect both dogs and humans, so it is vital that we offer our greyhounds the broadest possible protection.

Free webinar explores congenital heart disease in dogs

A free webinar is to provide veterinary professionals, dog breeders and pet owners an new insights into congenital heart disease.

Chris Linney, a cardiology specialist and Veterinary Cardiovascular Society (VSC) member, will present the webinar from 7.00pm to 8.30pm on Wednesday, 12 November.

Dr Linney will explore the types, causes and clinical presentation of congenital heart conditions. This will include diagnostic approaches, treatment pathways and emerging research opportunities.

The session is the third to be organised by The Kennel Club, with the VCS, following an introductory webinar and a talk on acquired heart disease. Dr Linney's webinar consists of a one-hour presentation, followed by a 30-minute question and answer session.

Dr Linney said: "This webinar will be an opportunity to deepen understanding - not just of the diseases themselves, but of how breeders, vets and owners can work together to support affected dogs and improve outcomes for future generations."
