hi im new to posting so ill do my best.we have a beautiful 10 week old staffy pup and have had her for 2 weeks ,she is very happy,healthy and playful and loves the other dogs myproblem is she gets very scared when new people come to our home she puts her tail between her legs her ears are back and disapears she will come back when we call her but is very timid,am i expecting to much of her at this age,she is due to go to puppy preschool in 2weeks but im worried it might be to much for her or do i leave it a bit longer to socialize her,she came from a reputable breeder and brought up in a good enviroment,hopefully someone can help me as we do not want to make any mistakes.
