Pedigree dogs may be more likely to need pet medication as they have a greater chance of suffering from hereditary health issues.
That is according to Helen Williams, head of Sainsbury's Pet Insurance, who was commenting on research by the supermarket that revealed the average pet insurance claim has risen by 34 per cent over the last 12 months, the Press Association reports.
Sainsbury's said that the average cost of bills sent to it for pedigree dogs cost £469.20, up from £416.35.
Ms Williams told the news provider: "Those with pedigree pets can often face even higher veterinary bills because these animals often suffer more from hereditary health problems."
Despite the rise in prices, the insurance provider also found that less than a third of owners take out pet insurance immediately after getting their animal. A tenth waited six months before getting insurance.
This follows recent research by the Co-operative Insurance, which found that owners spend £326 per year paying for medical treatment and taking time from work to care for a sick animal.
