But before you rush out to buy a cute pup, take a look at these rescue animals who deserve forever homes with owners who will make them feel loved and secure.
Chesterfield RSPCA has several shih-tzus including four that were brought in with overgrown fur matted with months of grot and a cross breed who slept on a bed of straw in a shed with a leaky roof. If you want to adopt a dog, head over to www.chesterfieldrspca.org.uk to register your interest.
1. Bob
Bob is a 13-year-old cross breed male who is a gentle dog. He suffered much hardship in his earlier life - his home was in a shed where rain seeped through holes in the roof, he slept on a bed of straw and his bones must have ached with the biting cold.
