Vaccines given to dogs are making them ill, a pet charity claimed yesterday.
Profit-hungry drug companies and vets are ‘frightening’ dog owners into inoculating their pets more often than necessary, according to Canine Health Concern.
Some puppies have developed conditions including autism and epilepsy after a raft of injections, it warns.
Catherine O’Driscoll, from the charity, said: ‘We are not anti-vaccination. What we are saying is that currently our pets are receiving far too many.
Puppies are vaccinated against distemper, hepatitis, parvovirus, leptospirosis and parainfluenza up to three times by the age of four months.
They may also be immunised against coronavirus, rabies, Lyme disease and bordetella or kennel cough. Booster shots are given every year or every three or four years.
But some have suffered dramatic changes in behaviour or been diagnosed with cancer within months of the injections, Canine Health Concern says.
In a letter backed by 17 vets and other pet experts, the charity has called on the Veterinary Medicines Directorate, which monitors animal vaccines, to issue new advice on their use.
Mrs O’Driscoll, who believes cats and rabbits could also be at risk, added that a simple blood test would determine whether an animal needed a booster shot.
