If I were you, I'd stop reading the different ads for dogs. Your heart is too big and you and your husband can only handle so many dogs. People who continue to add to their family can sometimes end up hurting the very dogs they love. You have to try and keep your emotions out of this and decide if you realistically can handle four dogs, but remember, every time you add a dog, you'll be taking time from one you already have. God Bless you I think you're wonderful!
