Recently bought lockdown dogs are becoming stressed as owners return to work.

More than 44% of dog insurance policies now include cover for “bad behaviour”.

That’s an increase of 13% on the previous year.

It’s estimated more than three million dogs – mainly puppies – were bought during the Covid-19 pandemic.

Most were taken in by young people to help cope with companionship and exercise routines.

Now lockdown restrictions have almost ended many of those dogs are being put up for adoption.

The Dogs Trust, a dog welfare charity, said a number of puppies were suffering from separation anxiety.

The signs include destructive behaviour, unwanted toileting, and howling and barking.

In some cases, anxious dogs may tremble, whine or pace around.

Some pets might need expensive professional.

Brian Brown, at insurer Defaqto, said:

“However, there is no excuse for not training and socialising a dog properly and insurers will not pay claims where this is the case.

“If your dog is showing signs of distress, seek advice straight away.

“Many insurers offer free vet helplines where you can get advice over the phone, even if you don’t have to make a claim.

“If you find you don’t have insurance cover, speak to the animal charities to get advice.”
