I gave my time and expertise to Street Hearts BG earlier this year and was simply amazed at the level of commitment and dedication Emma and Anthony have for a project they have essentially stumbled into. They began neutering street dogs with their own money in an attempt to reduce and control the terrible street dog situation in their local town and ended up caring for, rehoming, and rehabilitating more dogs than it is sensible to have at any one time. They are currently fundraising to give the dogs they have a chance at a good life - you can help by clicking on the picture below:
Changes to the 1991 Dangerous Dogs Act came into effect on 13th May 2014.
The National Animal Welfare Trust has distilled the important information here.
Your dog must be under control in public and on your own property. Dogs that display threatening behaviour (even in the home) could land you in trouble with the police. Fines and prison sentences are set to increase for some convictions and your dog no-longer has to bite to be deemed dangerous.
The NAWT has this advice sheet regarding the new legislation.
Threatening behaviour towards a stranger or visitor can be as simple as growling, barking or lunging. Make sure your dog is under control at the door.
Landela Dogs offers 'Ding Dong' training if your dog has trouble staying calm when visitors call.
