Hundreds of ‘lockdown puppies’ are being resold or handed in to rescue centres – because short-sighted owners are struggling to cope only months after buying them.

Sellers have flooded pet websites with adverts for dogs aged between six and 12 months.

Many owners admit they either do not have the time or the money to look after them.

The price of puppies surged to more than £3,000 for some breeds last year as many people started working from home or were furloughed.

Dozens of adverts have now appeared on sites such as Pets4you and Preloved as owners hope to recoup their costs.
