These are Lahore Bells with a big difference. Normal Lahore Bells are made for Falcons and Hawks so they can heard over long distance, and with Dogs it as the same except for one thing Dogs mooch about in undergrowth, and light weight bells when in an argument with undergrowth will lose, many times over the years we have tried to make the bells to be tougher but the sound was compromised, now we have made a bell that is stronger but still has the sound quality you expect. 

Please note: dogs can still lose these, that's the dog not the product
