Can any one tell me the pros & cons of jointly registering a dog please.  Many thanks.

Depends on what you mean -should be little or no problems if it is say husband and wife at the same address, but a lot more to think about if it is with the breeder of the dog or with a buyer of your puppy or with a friend of yours. If it is with somebody outside your immediate family, you need to put all conditions into writing -who pays for what, where will the dog live, are there any conditions re breeding etc etc. The short answer is -always simpler to be a single owner unless it is with your other half.

Thanks Goldmali. Single it is.
