I sympathize with you, or your husband, firstly try to discuss the difficulty with your neighbours, if this is unsuccessful you can report the noise to the Environmental Health Officer at your LA, keep a diary first of the dates/times you are affected by this noise to show to the EHO, this action may not endear you to your neighbours.
If the animal, usually a dog, is left for extended periods on their own you can report this to the RSPCA under the Abandonment of animals act 1960, if the RSPCA believe it is justified they may prosecute.
