If you have adopted a puppy or adult dog that has been abused in the past, helping them adjust to a new home, and a better life can be difficult. Although it may not be apparent at first, over time, you will notice the signs and behavior that indicate that your pup or dog has been abused or mistreated by a past owner. In such a situation, you must understand the discomfort and fear that your puppy might be experiencing and patiently help them overcome their distress and get used to a new, loving home and family.
