I don't have any tips, but you are obviously very loving and great dog owner. I am a cat person, but even they can be very frustrating, and kittens, forget about it! They drive you nuts (but it's worth it!). Just know this is temporary. I'm sure you'll figure it out. Take the good advice, and leave the other. 8 was harsh, but remember, it was said by someone who is a friend of a member, who doesn't know who you are, or what you went through with your other dog. Take it with a grain of salt. You know it isn't true, and so do most of us.
