A new form of pet medication used to treat dogs with depression, anxiety disorders and other psychological problems could be available in the UK later this year.
Prozac for pets could help to treat 80 per cent of the UK's eight million dogs, an expert has said.
Dr Claire Corridan collected research from over 1,300 dog owners, who observed their pet over a two-week period.
She found that the problems found were mainly due to owner spending too little time with their dogs.
"We all have busy lifestyles, so quite often cats and dogs are spending less time with their owners and less time being socialised," Dr Corridan said.
The new pet medication, which is made by Prozac developers Eli Lilly, is expected to be licensed later on this year.
One critic of the new drug, Beverly Cuddy, editor of Dogs Today, said that giving dogs medicine for their problems is not normal.
She said that many people want their pet to be perfect by this means normal doggy behaviour is not being tolerated. "There are lots of things you would prefer your dog not to do, but that is part of having a pet," she said.
