When Sue and Robin McGibbon took their beloved labrador Abby for her annual check-up last month, they thought the most they had to worry about was slightly increased creakiness in her joints. ‘She’d had problems with arthritis for some time, but it was growing worse and we didn’t want to see her in pain,’ says Sue. ‘Our vet had always tried to treat her with homeopathic remedies, but this time he gave her an anti-inflammatory drug.’ The family took Abby home, hoping life would become more comfortable for her. Instead, she suddenly became seriously ill.
