When an adult moves from one house to another there is always an adjustment period. You will have to work with the new dog and train them.
I have a black and white female who is very sweet good with us and our daughter (our daughter is a well trained child of 5yrs) but due to two deaths in my family last fall followed by covid she has not been off my rural property. She is leash trained and goofy and loves attention. She is good with my daughter and likes to follow me around. She is hood off leash but does not know sit down or stay as these are three command we do not use in our household. She is about 25 pounds so on the smaller side. $2500
