Hi! That is such a broad question, is there anything in particular you'd like to know?
If I could give you a single piece of advice from a personal stand point, it would be : be patient. Whether you're getting a puppy or an adult rescue, your dog will need training and time to settle in to their new home. They won't be the perfect pet right off the bat, and the bond may take time to develop. Just don't give up, hang in there! If you put in the time and effort, having a dog is one of the most rewarding experiences!
