There's good news for fat dogs, as UK pet owners will now be able to get special medicine from vets to help their porky pooches lose weight.
Just like humans, being overweight can be unhealthy for animals and vets say fat dogs often have problems with their heart, lungs, liver and kidneys.
One in five dogs in the UK is thought to be overweight and this can cut up to two years off a dog's life.
Owners are being told to combine the new drug with more walks for their pet.
And they're being advised not to feed it too much either.
The aim of the drug, called Yarvitan, is to stop fat from food being absorbed by the dog's stomach and digestive system. It also helps to reduce its appetite so it eats less.
The medicine, which must be prescribed by vets, claims to help chunky canines lose up to 10% of their body weight over two months.
