To be honest I have always found the recommendation by some places that you not include the dog's name utterly ridiculous. :lol: Why not? Having had dozens of cavaliers through rescue, most of them strays with no known name, I have yet to meet a single one who wouldn't come when called just about anything in a cheerful voice (take your pick of endearing term or just use 'Fido' and try it yourself). Additionally most dogs will within just hours or a day, adopt a new 'name' (which to them is just a sound that means something interesting almost always happens!). Only my shyest dog, Jaspar, would avoid going to someone he didn't know at all and he wouldn't go regardless of whether his name was used or not.
I think a very personal tag increases the chances of getting your dog back as it looks like someone really cares about the dog -- better than just a phone number on a tag. Also keep in mind that in many states, counties or countries (as in Ireland) owners are *required* to have their name, address and phone number on the tag!
For my dogs I have their name then my full contact details on one side and then on the reverse, it says "I am neutered and microchipped. Reward if found". I want people to know that the dog cannot be used for breeding (probably the number one reason why dogs are stolen at least in Ireland and the UK!! And cavaliers are a top breed to steal in both countries!), that the dog is chipped and that could be picked up by a vet if they are trying to steal the dog to keep, and finally, that there is of course a reward if any of my dogs are found.
For Leo and Lucy I have a second tag -- Leo's notes that he has a serious illness and need daily medication; Lucy's that she is deaf and if found to please put her on a lead immediately and call me.
Anyone is rescue will tell you it is very easy to get just about any dog to come to you. And frankly I'd much rather have my address and number on a tag and let people know where to find me even if they plan to ask for a 'ransom' then to never see my dogs again because they are going to be sold to some puppy farmer somewhere...
