I have seen a beautiful rescue dog on the RSPCA looking for a home. I think we're the perfect home for him but his name is the same as my 9yo DS. DH thinks this rules the dog out completely as it would be confusing. I think he's being ridiculous and DS is old enough to understand - we haven't asked his opinion yet as he'll be bouncing off the walls at the prospect as soon as we mention it and it's all very much prospective at the minute. DS doesn't have a nickname or anything we could shorten to and the dog is 3 years old so probably couldn't change his name!
YABU - you can't have a dog with the same name as your son
YANBU - your husband is being silly
