These treats are very smelly and my dog loves them, they are a real incentive for any dog, they are small and can be crushed to put on top of your dogs food.
These treats are really expensive, but a small pot lasts a long time. My greyhound loves them. He used to refuse to get into the car and I had to lift him in(a 31kg, 28" long lump) two limbs at a time. This is now a thing of the past - the promise of a single liver treat usually gets him bouncing in, even when we are going home. There are some other good treats, such as Harrington's training treats, but they do not have half the pulling power of the liver!
