Heart disease

Extra pressure on joints can make moving painful.
Shortened lifespan
Studies show that overweight dogs live up to two years less than healthy-weight dogs.

If you notice any of these signs, don’t worries, with the right support, most dogs can return to a healthy weight and enjoy life to the fullest.
