How to measure your Bull Terrier?
1 Neck - Measure your Bull Terrier's neck on the middle using a tape. Pull the tape snug, but not tight.
2 Chest - Measure the chest right behind the front legs, on the broadest part of the chest.
3 Back length - Measure the length from the base of the neck where the collar sits, to the base of your Bull Terrier's tail.
