Naturally we probably did what we could to make her more at ease during her last days. The happy news is that you will be getting a full-size dog so you understand what to expect in that sense. Unskilled shelter staff might place a strong-willed, dog with an old couple or a busy couple with babies.
Many older dogs entering a new home won't behave well. That is due to the fact that the dogs are concerned and don't feel safe in the new home. Don't take this behaviour personally and try to not become indignant. From another standpoint, some owners make the opposite mistake and become too indulgent with these dogs. If you get a second hand dog, you have to find a middle ground. You are in control and you want to show it to your dog. Behaviour issues are minimised when your dog feels secure and has a leader ( you ) that he's assured can protect him. Here is a top page on large dog pet beds.
I recognise that not all shelter dogs will come with issues, but because plenty will, it's often best to start your relationship on the grounds that issues should be predicted and dealt with.
