Just over 8,000 stray dogs were picked up in Wales last year and across the UK, five dogs are abandoned every hour.
To help combat the problem, the charity is asking dog owners to get their pets micro-chipped.
From April 2016 across it will be a legal requirement across England, Scotland and Wales to micro chip pets.
Across the UK, Dogs Trust has taken 43,771 calls from people trying to give up their dogs in the last 12 months – that’s 120 calls a day.
