My experience is mostly personal I grew up with dogs(small or big breeds). I also watched my neighbors or friends dogs mostly small I felt more comfortable with them and the people trusted me with their pets.I can enjoy large breeds also but I am more comfortable with medium and small breeds I know I can give them more of my attention, love and affection.Walking and socializing them in general is my way of keeping them entertained. I enjoy the company of the dogs and I would like for them and their owners to go back home with a awesome sensation of joy and relief both for the dog and the owner. I am willing to work with my availability for the happiness of the pup.
