You may have read that it takes about two weeks for a dog to adjust to a new home, this may be true of a very well adjusted dog with no trauma or stress to cope with, it can take many weeks or months. This doesn't mean lots of work but patience and consistency are most important. Please do read the information given with the homing paperwork. The most important piece of advice is to have no expectations, think of the dog as if it were a puppy and anything it does know is a bonus. Please don't put the dog under pressure ie. having lots of visitors, taking for long walks etc. Give the dog plenty of time (at least 7 days) to adjust to its new home and family before introducing new people, things and places and then do so gradually.
